[PHP] Re: Delete Temporary Internet Files
Hmm.. This shouldnt be a problem from what I know. Though it woldt be a perfect system, all you would need to do, is have a script that does : 1: Read the IE cache directory and puts all the entries into an array (all the files), 2: unlink all the files in the array. This would in my opinion work nice, except that alot of the files you cant delete at a given time, just try doing it manually. But itll clean the most. I wouldnt recommend this way of doing it, but it should work. As for other files on the windows system, just be sure that hey arnt write protected, as PHP cant unlink / delete them then.

By issuing this command into EXEC and pulling the output, and the IP is the name of the machine your locating, youll get what U want. nbtstat -a 1.2.3.4 This will tell you the share names of that computer, and you will be able to know the names of the shared drives to access. This would have to be done to all the IPs in order to gain access to all the shares. After this you have to parse each line from the output, and look for the <20> folders, which indicate an open share. Be aware that you should not open for this type of networking outbound to the internet, as hackers easilly can access your machines as well. I preferr installing 2 network cards in the machine, one for local network and 1 for internet, where the internet network card is blocked for NETBIOS over TCP/IP, and the local network connection is opened. If U only have 1 network card in each machine, I suggest U get a router with hardware firewall, where U insert the internet connection directly into the router, this will prevent NETBIOS over TCP/IP from the Internet.

Re: [PHP] Help with scripts to add records to a database
Important to mention, that the reason why the
$variable
probably doesnt work is that your service provider
has turned off the globals. In this case you would need,
as Zhuravlev mentions, use $_POST["variable"] to
insert the records. All in all, since the factory setting in
the new versions of PHP are Globals off, using POST
and GET is much better practise, so just start using it, :)
And ofcourse :
If U are using GET method in your form, then you use
the $_GET["variable"] instead.
You probably also know, that the way U are writing your
code isnt very handy in the long run, if you alter your
database you will need to recode all the pages that inserts
anything. You probably know the names of your table, so
I would recommend you do this instead :
Say the table is like this, and to quicken my typing I
assume globals is on, :)
id
first
last
phone
You would write :
insert into contacts values ('','$first','$last','$phpne');
You should write this :
insert into contacts (first,last,phone) VALUES ('$first','$last','$phone');
WHY?
If you alter your table, insert a new row or remove
one, your example will fail mySQL and result in an
error since the query doesnt match the table. In my
example it will have no difference, aslong as first,last
and phone are still in the table. The autoincrement
value will still be updated as intended, aslong as the
table is correctly formatted (and it is, since your first
example works).

Re: [PHP] Re: Delete Temporary Internet Files
The original question didnt consert the OS, or where the user was at. Concerning cleaning the IE directory I would assume that he's installed PHP and IIS / Apache on his local machine. Using a webpage online on the internet to fix your local machine doesnt sound logical to me, therefore I assume local innstallation on local machine. And when your on your local machine there are no problems accessing your files, even if they belong to the windows environment. Overwriting them can be problematic at times, since processed may use the file.

Re: [PHP] Re: Delete Temporary Internet Files
hehe, To me it I could say the same, why on earth would you want a script to alter the internet options when its up under Tools/Internet Options anyways? The sane sollution would be that some people have strange ideas, some people like to do things their own way. I myself often create PHP scripts that does alot of filework on my PC, since I know PHP and dont know Visual Basic. Therefore PHP is the "naturural" choice of programming language for me, and therefor probably for alot of other PHP people. The question regarding the Internet Options does boggle me aswell, :) I feel that me and U arguing about this is plain silly, until we get some more input from the OP comes with some more "feedback" on excactly what he wanted, :) On the other hand, if (And I think not), that the internet options (And I have to believe that we are talking Internet Explorer, based on the fact he earlier mentioned cache files, could be Opera however) are controlled from an .INI file, this also should be no problem on the windows machine.

Re: [PHP] Calling PHP functions from within javascript
"First thing is, it's possible" First of all PHP is server-side and has nothing to do with client side. If you have managed to do this, you must have some concepts screwed up! Lets not believe that PHP is client side all of a sudden! Sorry mac -> But you havnt done this in the past! a) On the other hand, there is a way you can do what U want -> thanks to the fact that Javascript is able to load a datafile. If this file is a PHP file that is processed serverside you will accomplish your goals. b) Latest addons from Microsoft into Internet explorer makes the loading of ekstra files through XML modules very flexible and easy. Ive done this myself and it works like a breeze. If you here load the XML data, instead the data is your DB data and use this in your JS as the XML parser has loaded it into variable... You have accomplished your goal. That was 2 sollutions you could use, were noone are any good really. Ive made some sites myself that are interactive in many ways earlier, and come to the conclusion that the pages just have to become bigger. An example, a webstore sollution I have developed has an interactive menu selector buildt in javascript, which stores all possible category combinations. To keep it short here -> This javascript after its buildt by my PHP is 120KB, and makes the HTML very large, it ends up in like 150 KB. Point is, if there were a sollution you are talking about -> I could have shrinked the 120KB kode down to 10KB instead, just pulling out the data from the DB that the customer aquired. Ive spent hours looking for this sollution, and above you got the ones Ive come about, where the XML is the one accually working. (Point out that the XML model doesnt handle ØÆÅÄÖ characters -> which resulted in me not using this. If it could handle this, XML would be my sollution!

Re: [PHP] $_POST bug?
My system (win2000 IIS) also handles 0, and webserver (redhat apache) also handles 0. Your system sounds faulty in some way, what browser are U using and what version of PHP. I know from earlier experience that some versions of Netscape behaves strange on the elements, meaning when posting / "getting" the data back to the server. I remember this as one of my "domain search" utilities always came "emtpy" in netscape, and not in Opera and Explorer. So it could be this, but if youre not on Netscape -> Its not this. :) Kim -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Calling PHP functions from within javascript
"scripting techniques and a hidden iframe" Ahh... Nice one! This accually didnt come to mind at all for me, probably because this sort of scripting soon gets very complicated given that such applications are supposed to work flawlessy for the end user. And to many loading windows (hidden frames), and scripts waiting for pages to load is - atleast in my experience - not the way of doing things, as there has to be alot of "what if the data doesnt arrive..." scenarios. But hey, the author didt accually say what he was supposed to use this for, so I should be thinking to much application here.. But nice, we now have 3 ways of "doing" this. 1. Javascript, and loading external files. Bad sollution. 2. XML, loading the data. My favourite as you nicely pass GET variables into the URL you get, 3. And last, Javascript and iFrame/frames based loading. Again, bad move in my opinion, as in the end there is alot op PHP work here - and alot of javascript work here, and you could just do all with a little PHP. developer.irt.org has some nice articles for those of you who are interested in dwelling down into the javascript file method : http://developer.irt.org/script/file.htm also an article (havnt read it) about Javascript and DB, through data binding : http://tech.irt.org/articles/js060/index.htm Okidoki.

Re: [PHP] can I license a php script?
Robert has some interesting thoughts aswell here. I just wanted to complement the stuff about securing your scripts. Zend has Zend Encoder, rather expensive - and with windows GUI. IonCube also has encoder, much more affordable, CommandLine. www.zend.com The first encodes and optimizes your code, and your server has 2 have the Zend Optimizer installed on its system for it to run. This has shown in history to be complicated on some ISP, who never gets their finger out and can install this. But usually, 4/5 it goes well. www.ioncube.com / www.ioncube.co.uk This one compiles and encrypts and optimizes (I think). It requires a module installed on the server, but -> It can also run on most modern apache systems where it installs on the fly (the decoder). Ive just purchased the licence for this product myself, and it looks really promising. Benchmarks on their page also shows that this software accually beats the Zend Encoder, and the price is far better to, :) If you are developing some sort of software, you should always protect it so that : 1) Your competitors / resellers doesnt fuck you over by "selling" without you knowing it, or "fix" your code to fit their needs without you getting credit /payd for it. 2) Your customers doesnt play "developers" and try jerking your scripts, which in the long run gives you alot of extra support time as the scripts go bugging out.

[PHP] Re: get some part of text
Well, still no problem.
If there are only one instance of the "job_resp errorCode" you
just alter the explode() abit.
Else, the clever part with array_push()
Let me do some online coding here, might contain some errors though, :)
$error = new array();
$yourstring = 'job_resp errorCode="4194337" description="Originator you"';
$temp = explode('errorCode="',$yourstring);
$count = count($temp);
if($temp>1){
for ($i = 0; $i < $count; $i++) { // Loop through the errors / exploded
ones step 1/2
$temp2=explode('"',$temp[$i]);
array_push($error,$temp2[0]);// Push all the errors variables into
an array step 2/2
}
for ($i = 0; $i < count($error); $i++) {// Print out all the errors
echo $error[0];
}
} else {
$temp2=explode('"',$temp[0]);
echo $temp2[0];
}
- - - -
The above example I use alot, I find pushing things into array beeing
a very handy way of doing things, as its very nice and handles n
occurencies.

[PHP] Re: Storing images
Well as far as I can see you have 2 options. a) Store them directly on disc b) Store them in a database (eg. mySQL) I would think that a) is the best way without doubt, since it doest use any extra processing power to serve the images to your visitors as its only the webserver doing the usuall stuff. The b) option has a better advantage regarding the backup function, as its easier backuping a database than backing up a directory with scripts anyway. (Unless you are thinking FTP, but right now im thinking automatied scripts) On the otehr hand I have succesfully installed ZIP ability with PHP, which makes backing up directories no problem. So all in all it depends on where you stand if you know what I mean. The database sollution puts extra demand on the database as it constantly has to query the database to get the images all the time. So if you are thinking about the health of your server, and how quick you want your site to accessible for your visitors I would stick to a) I dont think it good practise to store images into the database either. -- Kim Steinhaug --- There are 10 types of people when it comes to binary numbers: those who understand them, and those who don't. --- "Paul Marinas" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] > > Hi, i was wondering which is the best way to store images.

[PHP] Re: Alternet row colors
Well, first of all Ill just scrap you script since this one is so easy
its better to do it from scratch.
OK, somewhere in your script you have the code that accually
aoutputs the tables you are working with. Im refferring to lines
here, and Im meaning the bottom of this document which is
the scipt you posted, and I have numbered the lines.
Overview of your script.
Line 5 - we print out the table header
Line 11 - 23 is the loop which prints out all the lines, or rows.
Line 24 closes the table.
So what we have to do?
First we need to declare the values we want to use as backround
colours, lets use logical names :
(fig a)
$backcolor1="#fafafa";
$backcolor2="#c0c0c0";
$backcolor=$backcolor1;// we assign color 1
This code has to be written before the loop starts, so somewhere
before line 11.
In the loop (11-23) we need to switch between the colours where
we write the colour of the . So we write something like :
(fig b)
echo '';
// continue with the rest of here
// which is -> your code.
This will print out the first background color, nice. Now we need it
to switch color, so we need to add a little logic. This will be inserted
right before the loop ends (infact, you can put it where ever you like
aslong as its in the loop).
(fig c)
if($backcolor=backcolor1)
$backcolor=$backcolor2;
else
$backcolor=$backcolor1;
As you see above the logic is quite simple, if the color is 1 -> we set it
to 2,
else we set it to 1. If you think of it, if you process this logic over and
over again
you will infact get 1, 2, 1, 2, 1, 2, 1, 2 all the time, :) Nice!
There you have it, and I hope you got the hang of it.
To take your code and implement my colorswither all you need to do is,
1. On line 21 replace #00 width $backcolor
2. Insert the logic (figc), all lines, into line 19
3. Place fig a in line 4.

Re: [PHP] Re: Alternet row colors
Thanks for this tip, i used to use this when I programmed Perl.
But I didnt know it worked here aswell, hehe.
Absolutely true that this is much better code practise, and it
eases up the lines in the code.
Great tip!

It's so much easier to use the mod (%) operator:
using the mod operator, you can check if a variable is divisible by some
other number without leaving a remainder.
For this example, we want to change every other row, so we would compare
our $count against 2 to see if it leaves a remainder:
$bg = ($count%2==0) ? "#00" : "FF";
What this line does is FIRST, it checks to see if $count/2 leaves no
remainder. If this is true, it sets the $bg var to "#00"
If it is false, it sets $bg to "#FF"
It only requires the addition of one line of code, and to replace your row
background color with a php variable.
Also, you don't need to use printf(), since you aren't specifying any
formatting.
See code below:
code:---
$result = mysql_query("SELECT * FROM albums where id <15");
$Count = @mysql_num_rows($result);
echo "\n";
echo "IDARTISTTITLELABELPRICE\n";
for ($count = 0; $count < $Count; $count++) {
// Extract post details from database
$myrow = mysql_fetch_array($result);
$id = $myrow ['id'];
$artist = $myrow ['artist'];
$title = $myrow ['title'];
$label = $myrow ['label'];
$price = $myrow ['price'];
$bg = ($count%2==0) ? "#00" : "FF";
echo "$id$artist$title$label
£$price\n";
}
echo "\n";

[PHP] Re: Table statistics
Well, Im about to create some statistics systems myself and havnt really starter thinking of the "optimal" way of doing such calculations so this thread will be much interesting. I would suggest the following : As you have already pulled out all the data from that month, we need to prosess this. I would create a 2 dimensional array for every Screen_ Name, // Initiate array $count = array(); // Loop through your data and assign all the users like this $count[$Screen_ Name] = 0; This will give you an array of all the users, then you could loop through the data again and add 1 for each instance of the user to meassure the counts : $count[$Screen_ Name]++; Finally you sort the array and print out the first 5. (The 2 last steps should be put together since its no use going through the data twice) -- Kim Steinhaug --- There are 10 types of people when it comes to binary numbers: those who understand them, and those who don't. --- "Daniel Harik" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] > Hello, > > I have table with messages, and i have users table, the are linked via PK > UserID -> UserID, what i need is to select Messages for current month and > calculate top 5 posters list for current month. > > I have create following query but it's not complete: > > SELECT Handle, Screen_Name from MBoard where Message_Date>='2003-11-00' ORDER BY Handle; > > this gets me all messages posted this month ordered by userid > > > Thank You. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Hello! This one : http://www.phpclasses.org/browse.html/package/870.html I remember doing the "zip" research a while ago and tested several classes and methods, but this class was the one that worked flawlessly! Ive installed and used this class myself, and it works on both linux and windows. This can zip down a directory of 1GB of data (tested), and depack it to another directory (tested). You can also extract single files out of the directory.

Re: [PHP] Storing images for photo album?
Yes, What system are you using for generating the thumbs for your images? ImageMagick or GD? If you are able to choose you should by all means choose ImageMagick since its much more powerfull than GD. Ive been using both (meaning, I use GD as a second sollution where Image Magick isnt available, for extra compability) and never run into memory problems. Only thing to remember when batching many Hi-Res images that the default timeout is 30 seconds, but aslong as you are processing 1 image into several others this should never be a problem.

messed up (apparently), and removed the error_reporting.
Result gives this :

[PHP] Arrays and performance
Something Ive wondered about as I started working with XML. Importing huge XML files, and converting theese to arrays works indeed very well. But I am wondering if there are any limits to how many arrays the PHP can handle when performance is accounted for. Say I create an array from a XML with lots of childs, say we are talking of upto 10 childs, which would give 10 dimensional arrays. Say we then have 10.000 records, or even 100.000 records. Will this be a problem for PHP to handle, or should I break such a prosess into lesser workloads (meaning lesser depth in the array)? Anyone with some experience on this? -- Kim Steinhaug --- There are 10 types of people when it comes to binary numbers: those who understand them, and those who don't. --- -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Arrays and performance
Thanks for your reply! Im going to use this for a backup system for our webstore system, where some of our customers have *alot* of products. Given the structure of the database with categories and images 5000 unique products quickly gives 3x = 15000 arrays. But again, how often would the client need to revert the backup? Ive never needed to do it for now, but I still want to do this backup system in XML (Looks kinda up to date, :), and at the same time know that it will eventually work -> even for the customers that infact has alot of products in their system. The alternative, would be that customers with >x products would only have access to mySQL dump. Or to have a script that evaluates the XML file and prompts the user that this file is to large for automatic import / revert. a) >From what I understand of your answer you're telling me that PHP itself will not have any "problems" working with 1.000.000.000 arrays, aslong as there are enough ram and processing power available, and that the timeout is extended. Or would the PHP die a painfull death as soon as it gets "to much" data? Could we coclude the follwing, XMLfile > 200 MB = No PHP! b) I should do some benchmarking, to find the "magic" marker for how much XML data that is "affordable" to grab when done on a webserver with other clients to prevent angry customers or failures due to factory timeout setting to 30 secs. -- Kim Steinhaug --- There are 10 types of people when it comes to binary numbers: those who understand them, and those who don't. --- "Raditha Dissanayake" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] > Hi, > > I belive PHP should be able to handle it but it's a bad idea.

[PHP] Re: Max File Size exceeded
You are probably referring to >2mb filesize. The default setting in php.ini for uploads are 2 MB. As far as I know there isnt any good way of checking the filesize client-side. You could however use some sort of java-applet I would think for the upload system - this would be able to validate the filesize I guess. The other, and probably the only sollution, would be to modify php.ini on the server to handle larger files. If your on a server with other customers you will probably have a hard time getting your provider to do this as most people have no use for larger files.

Re: [PHP] Passing vars w/refresh w/register globals off?
Well first off all it is possible to post and get at the same time. Dont know why you want to, but its kinda easy really : Example : You can submit this form several ways, with ordinary submit button, or with javascrip submit. If you really want to keep serving variables that shouldnt be visble in the browser or in the html kode I guess the only way would be using cookies. But if the variables are defined by the users input / behavior there is surely the need of showing the variables one place or another. You mentioned that there were up to a 100 variables to be passed here. Was that pr user or in total? Sending like a 100 variables with GET would be a bad idea all together, since there are limits on how many caracters the URL can hold. Some years ago alot of browsers had a limit on 128 characters, this is imporved by the years but still the only way to feed long sets of data is through post. If all your variables can be stored on the server, assigning a unique ID to the session would make you able to store everything in the database as someone mentioned earlier. This wasy all you need is pass the ID within the browser. By checking the ID against the unique session on the server you will also eliminate tampering with the data. Webpages that has like a 100 hidden fields doesnt look very "professional", but hey - it works. The other thing is that forms can also talk with eachother nicely, what I mean is that you can share the informastion with the help of javascript. Storing all the information you need for later in a form somewhere in the html page, then when you build the refresh url you just pick out the data you want to use from the different form elements (document.form.variable.value).

[PHP] Re: Change Date
Is it me or are everyone responding how to give a the date in here? The timestamp is still time() and not date() isnt it? Timestamp works in seconds, so 1 hour is : 60 seconds * 60 minutes. $hour = 60*60; $day = 24*$hour; timestamp for 125 days into the future would then be, $futuretimestamp = time() + ($day*125); time() returns the current timestamp, this very second. All you do is calculate all the seconds there is in 125 days and add it up. If you want to go back to the future, you subtract it from time(). Then, when you want the date to be entered for the screen or somthing use the date() command. -- Kim Steinhaug --- There are 10 types of people when it comes to binary numbers: those who understand them, and those who don't. --- "Sadeq Naqashzade" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] > Hi, > How can I find time stamp for example 125 next days. or 03:30 hours next? > > Regards, > S.

Is there any way in Outlook Express I can remove theese posts, or do I have to see them topping the list every time I check the lists? Ive tried several ways now, but I cant seem to fix them. Any help would be appritiated? Maby I should change newsreader? -- Kim Steinhaug --- There are 10 types of people when it comes to binary numbers: those who understand them, and those who don't. --- -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Good Morning
I am working with PHP 4.0.6, and I do not obtain to send given of the page
for the printer. I use function " PRINTER_OPEN() ", I make the manual in
accordance with, exactly thus it gives an error to me of indefinite
function. What it can be?
Fatal error: Call you undefined function:printer_open()
$print = printer_open();
$print = printer_open("LPT1 ");
printer_write($print, " Test of printer ");
printer_write($print, " Test of printer ");
printer_write($print, " Test of printer ");
$print = printer_close();
e this error it even gives to me with function " PRINTER_WRITE() ", could
give tips of that he can be happening.
Yours truly.

[PHP] Upload issue - The 2MB barrier...
As the default setting for file upload is set to 2MB, we usually get a problem since we cant always access the php.ini on every server our scripts should be run from. After looking in the php.ini file on one of my webhosting partners I noticed an interesting (in my opinion) thing with the post settings which read : (And to make it clear, I could easilly change the php.ini file, but due to the other clients on this webserver I cant... Im not alone here ) post_max_size = 55M Since the other setting would easilly accept say 5 MB I wonder, would it be possible to upload an image "as a POST"? Or something like this? Maby this is a pointless idea to investigate further ? -- Kim Steinhaug --- There are 10 types of people when it comes to binary numbers: those who understand them, and those who don't. --- -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Upload issue - The 2MB barrier...
Hmm
1. We can rule out the ini_set()
2. We can now rule out the .htaccess
Tried the following :
.htaccess
php_value upload_max_filesize 5M
testfile.php
print 'upload_max_filesize = ' . ini_get('upload_max_filesize') .
"\n";
The testfile succesfully states the new value, but it doesnt work.
Obviously, the documentation on php.net already told me so, so the fact
that I really tested this is kinda stupid... hehe.
That leaves me with the httpd.conf settings which is supposed
to work, also according to the PHP documentation. Just need to
locate this file first...

Re: [PHP] Upload issue - The 2MB barrier...
I found the file, but since im on a Cpanel server I do have to do some checking with the admin so that I dont mess up for other users. I wouldnt want my experimenting resulting in an unstable server for other users, :) It looks like this is the only way to alter the settings.

[PHP] Re: Dealing with large classes over several files
umm... It all looks good except this one :
function foo::f ()
This is where you get the T_ error. Dont know what you are
trying to do here, but thats the error anyways, :)
Your first example is all correct,
// myclass.inc.php
class foo
{
// constructor and destructor
function f () {}
}
Dont know if it helps you though.

[PHP] Opening large file problem - fopen
Hello
Im having real problems working with large files in PHP. At
the moment Im trying to parse an error_log file, and it works
like a charm, except that the scipt stopps after parsing around
70.000 lines, or around 8MB of data. Im using this :
$file= "error_log"; // 280MB file
if($fp=fopen($file, "r+"))
{
while($line=trim(fgets($fp)))
{
// Do the business
}
}
Surely this is not the way to work with e.g. a 280MB file. I solved the
sollution by chopping the file into 7MB files, and adding a fileopen
loop around the script above which solves my problem. But ->
How do I parse the 280MB file all in 1 go?
I have plenty of timeout and plenty of RAM in the php.ini file, so the
problem isnt here.

[PHP] Re: Opening large file problem - fopen
I found out that what the script accually does is choke on "\n\n",
empty lines. I havnt found a way to solve this with the script,
What I do now is use TextPad and just replace all occurencies
of "\n\n" with "\n-\n" or something and it works all nice. But this
is a bad way of doing it, since the script still doesnt accually work...

Re: [PHP] Re: Opening large file problem - fopen
Hello,
Thanks for you reply. The first approach works, I succesfully
imported 1.903.541 entries into my mySQL database, phew!
Problem was that as mentioned I had to "massage" the data
beforehand, which with TextPad didnt take to much time but
again I love my scripts to be complete and be "standalone".
Back to the 2) option, I tried another approach, just to see
how far the script woul accually go. There are ~2,1 million lines
in the error_log so I would like to see a result for the $i in this
range. But this script also chokes.
$file= "error_log";
$handle = fopen ($file, "rb");
$contents = "";
do {
$data = fread($handle, 8192);
if (strlen($data) == 0) {
break;
}
$contents = $data;
$temp = explode("\n",$contents);
$i = $i + count($temp);
if($i%1000==0) // Spit out every 1000 lines count
echo $i . "";
} while(true);
fclose ($handle);
echo $count;
exit;
Do you have an example, or link to a site discussing the issue, of
buffering the data?

Re: [PHP] Re: Opening large file problem - fopen
Attached is a little textfile on 4 lines, it will choke afte 1 line
due to the "\n\n" problem.
I use this loop to parse it :
$file= "error_log.txt";
if($fp=fopen($file, "r+"))
{
while($line=trim(fgets($fp)))
{
echo $line . "";
}
}

[PHP] racing NO domain names problems! (For nordmenn!)
To solve this problem you need a norwegian keyboard so I
might aswell type the whole question in norwegian, sorry gyez!
---
Jeg har støtt på noen problemer når det gjelder å konvertere
domenenavn mot Norids egen ACE konverter. Jeg har prøvd
med både POST metoder og GET metoder men resultatet blir
uansett det samme.
Jeg sender en henvendelse til Norids side, og ønsker å parse
resultatet, problemet er bare at Norids side nekter å godta selve
bokstavene æøå av en eller annen grunn. En metode er eks.
http://www.norid.no/domenenavnbaser/ace/?action=Convert&name=blåbær.no';
$fd=fopen($page,"r");
while ($line=fgets($fd,1000)) {
echo $line; } fclose ($fd);
?>
Som du ser på det som kommer ut godtaes ikke ÆØÅ.
Jeg har prøvd å sende "blåbær" som "bl%E5b%E6r.no" men samme problem.
Jeg tenkte kanskje det er en begrensning med GET eller at de har lagt inn en
sperre på GET for å bare bruke POST, men den gang ei. POST med sockets
gir samme resultat, uanhengig om man benytter "å" eller "%E5".
Blir POST data kodet annerledes en GET data, altså "å"=>"%E5"?

Finally!
The answer was this :

[PHP] Re: sql query and some math
Your first query, could it be that you dont have any reference between the
two tables?
You should have a link between them, like
where t1.id=t2id
Or else you do not have any reasonable way of predicting the outcome of the
query. Atleast this is what I know from my own experience.
Especially if t2 has more entries for each entry in t1, your query will
result
in unpredictable manner.
Hope this helps.

Re: [PHP] How do I protect downloadable files?
I would go for the 3rd alternative. There are several ways to
"stream" the file with the use of headers.
This way you can validate the user securely with your logon system,
and you can place the files outside the viewable web content.
Typically oputside your www / public_html folder.
I use this myself in an application I use, streaming files at 50MB
does not use alot of resources at all, atleast not the way I use.
My use for the script is to serve high resolution images to several
customers, often TIF images up to 50MB and larger.
Heres the code I use :
$distribution= "filepathonserver";
if ($fd = fopen ($distribution, "r")){
$size=filesize($distribution);
$fname = basename ($distribution);
header("Pragma: ");
header("Cache-Control: ");
header("Content-type: application/octet-stream");
header("Content-Disposition: attachment; filename=\"".$fname."\"");
header("Content-length: $size");
while(!feof($fd)) {
$buffer = fread($fd, 2048);
print $buffer;
}
fclose ($fd);
exit;
}

Re: [PHP] How do I protect downloadable files?
However I forgot to mention, all theese header tricks are real swell
indeed, but you should get hold of a friend on a macintosh.
The method I use doesnt work on the macintosh, so for the mac
users we just serve the files "as is", meaning they accually dont get
protected...
The other methods aswell should be tested on macintosh systems
just to be sure.

[PHP] Re: JavaScript Enabled?
Indeed an old thread this one, but I still would like to know if someone have some input on some ways of solving this dilemma. Surely it is easy to detect javascript when its enabled, but what to do when it's not enabled is a much more interesting approach. I have several systems online which (maby from old habits) heavily depends on javascript functionality. Surely I could easily remove all javascript and do all processing and validation serverside, but in my honest opinion I see no practical reason to ignor javascript in any application. The benefits of using java is far greater than the problems. SOLLUTION 1 - DETECTING THE CLIENT I would think that if we set a meta refresh to the noscript.htm and an onload javascript to switch to script.htm we could from theese pages set some session variables if the user has script or not. However this redirecting of pages is kinda silly I think, and I would like to think that there are other ways of doing this? Let us not forget that search engines would just love this sollution on our frontpage... Surely we could add this code and refresh the same page with ?jave=false or ?java=true, but for some reason I dont like this sollution. Meta refresh is bad. ALTERNATIVE SOLLUTION - POSSIBLE? Hoping someone has already solved this Im throwing some thoughts here. Since I use the session variable on all my pages, I could also create a fake gif spacer from a php script (eg. spacer.gif.php, which eventually spits out the gif but lets me do some stuff meanwhile at first). This gif could be called from javascript document write. A 1x1 spacer, which if I call this gif would mean that javascript would work, and if this script is triggered I could update the session with eg. script=true; Which would make me know if the user has it enabled or not? Atleast this sounds logical in my head, aslong as I dont need to alert the user at once if hes got enabled java or not. This approach would mean that I can alert the user with whatever HTML code from PHP I would want after eg. 3 pageviews, since he would surely have the triggered the dopcument.write by then. (Ofcourse if he has deactivated images aswell we have problems but hey... ) Alot of nothing here really, but maby someone have some thoughts on the matter. -- Kim Steinhaug - There are 10 types of people when it comes to binary numbers: those who understand them, and those who don't. - www.steinhaug.com - www.easywebshop.no - www.easycms.no www.webkitpro.com - "Richard Davey" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] > Hi all, > > Can anyone suggest a suitable means for detecting if a client browser > has JavaScript enabled or not? > > I know this isn't exactly PHP related, but I need to make sure my PHP > script offers an alternative in a friendly way and not a JS error, but > I just wondered if there was a foolproof method of doing this? > > -- > Best regards, > Richard Davey > http://www.phpcommunity.org/wiki/296.html -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] PHP logic - Whats going on here?
Ive stumbled onto a rather strange problem, atleast I cant see why this
is happening. Im using phpMailer to send mails, and I have the following
straight forward code :
$mail = new phpmailer();
$mail->IsSendmail();
$mail->From = '[EMAIL PROTECTED]';
$mail->FromName = 'From Name';
$mail->AddAddress('[EMAIL PROTECTED]');
$mail->Subject = $header;
$mail->Body = $body;
Then to send the mail we use this :
if(!$mail->Send()) {
echo $lang_error['mailer_error'] . "\n";
}
As you see above, Ive dropped the "what if all goes well" loop, since I
believe that the $mail->Send() is initiaded in the first statement
For some reason the above results in a blank mail, no $body at all,
rest is fine. However, if I include a dummy for if all goes well :
if(!$mail->Send()) {
echo $lang_error['mailer_error'] . "\n";
} else {
// Why do I need this one???
}
What I dont understand is why do I need the last else statement? Isnt the
result of $mail->Send() completed if I only check for !$mail->Send()?
Maby it would be better to write like this :
if(!$mail->Send()) {
echo $lang_error['mailer_error'] . "\n";
} else if ($mail->Send()){
// Why do I need this one???
}
The above would in my belief send two mails, atleast my logic tells me that.
The strange part is that when looking at examples from
phpmailer.sourceforge.net
they use my initial loop aswell, not the "Why do I need this one???" part.
Im beginning to wonder if there are something mystical going on with either
my
code or our servers. ??
Hope someone understand what Im wondering about here, hehe.

Re: [PHP] PHP logic - Whats going on here?
Thanks for your reply, it all seems logical when you think of it, still I also think it sounds logical without the extra ELSE statement since the function has to executed for the first IF to do the comparison, meaning that the email should be sendt in the first place. (If it didnt how could it state FALSE or TRUE, unless PHP only simulates the function if it falls outside the initial IF statement) However, no reason to argue the obvious, :D On the other hand, this would also mean that the exmaples from phpmailers homepage are wrong : [ SNIP FROM http://phpmailer.sourceforge.net/extending.html ] $mail->Body= $body; $mail->AltBody = $text_body; $mail->AddAddress($row["email"], $row["full_name"]); $mail->AddStringAttachment($row["photo"], "YourPhoto.jpg"); if(!$mail->Send()) echo "There has been a mail error sending to " . $row["email"] . ""; [ /SNIP] This is probably why I in the first place removed the extra ELSE statement, since I didnt see any reason for it. But in future Ill always include it it seems, :D -- Kim Steinhaug - There are 10 types of people when it comes to binary numbers: those who understand them, and those who don't. - www.steinhaug.com - www.easywebshop.no - www.easycms.no www.webkitpro.com - -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Re: dropdown box displays empty rule
Well, seems you have some confusing logic here, since you
print out the option before you check if it should be checked.
To top it off, when its accually checked you write out an empty
value, which really doesnt make any sence at all.
A quick rewite would be :
while($rowu=mysql_fetch_object($result1)){
if ($selected==$rowu->naamreis)
echo "naamreis\">" . $rowu->naamreis .
"\n" ;
else
echo "naamreis\">" .
$rowu->naamreis . "\n" ;

Re: [PHP] Using Post like Get
Since you are on the same server, I hope you mean the same domain. If not the session variable wouldnt work very well. But if you infact are on the same domain, you should look into the session variable and store everything you need. From what I know there are now limits on how much you can store in a session, that said I wouldt pump several megabytes into it... Several good answers here, but it looks like most of us agree on the session. Cookies can ofcourse also be used, but this also means that you require all your clients to have them enabled. Anyways, even when using cookies I always use session as the main system - cookies only works as a "saved session" in my systems. (Meaning, instead of having to logg onto the system again, the username and passowrd are stored in a cookie, this way the user can choose the famous "remember me" setting many of us enjoy). -- Kim Steinhaug - There are 10 types of people when it comes to binary numbers: those who understand them, and those who don't. - www.steinhaug.com - www.easywebshop.no - www.easycms.no www.webkitpro.com - "Dennis Gearon" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] > What I'm trying to achieve is to have the same cookie IDENTIFY a user on > different (or same) applications (on the same server), but require them > to log in for each application, and get a different session..

[PHP] Re: Upload problems
Just a quick question, Did you alter the upload_max_filesize to 500MB and the post_max_size to say 510MB and you succesfully upload 500MB files from one machine to the server? I never testes with filesizes that large, but It would be nice to hear if it accually works without tweaking to much. I would also think that the general 30sec timout would need to be altered as moving a 500MB file from /var/ to the users homedirectory and then do some filechecking on it and such would easilly need some extra seconds. Not to think of the overhead if many people upload large files at a time. Ok, its a vague post this, just looking for some input here, :D Its like the needle and the haystack, dont know what im exatcly looking for here, but you never know.

[PHP] matching system - anyone seen any?
I wonder if anyone have come across a script/system that already has this feature, else I would need to do it all over again. The scenario is this : I want people to select the movies they have seen and rate them 1/10. Movies not available in the "polling" system they can add, and rate them. This way the database is constantly growing, and ratings are constantly added. You can rate as many films you want, or noen if you like. Then, after you have rated you can "match" your ratings to find other people that match your selections. More like matching a profile really. There would be some sort of system inside here which could build a form of profile based on your ratings, and then compare theese profiles. I havnt really started planning how this would work, or should work, but first mainly if anyone has seen such a system around.

Is there a tool out there who can compare two folders, and generate a report on what files are new, removed and updated?

But when projects have over 500 files, and you have 50 customers it would be nice to just upload the files which are updated. I have a feeling CVS would maby be the trick here, but im not sure.

[PHP] Re: PHP graphing tool?
You will find a couple on phpclasses.org, also a few on sourceforge.net Some googling and youll find a few more. Ive been down the same road, finally youll see that accually there are no free ones usable for your project (atleast I had a real hard time finding some). There are some really great flash graphs out there, and the last year the pricing has dropped to a reasonable one aswell so you might aswell look at the comercial sollutions out there, they have become real good.

[PHP] Re: Resequencing logic
Well, this is much the same as any CMS system where you are able to sort the contents by your own, in your case song titles. One way to solve this is by using form fields together with your listings so that you have some sort of link to the posts in your database. You also need a field in the database that keeps track of the sort. You also need abit of javascript. EG. ID, SONG TITLE, SORTER Lets have some data, 1, Limbo, 5 2, Bimbo, 6 3, Cimba, 1 This will be presented : Cimba (1) Limbo (5) Bimbo (6) When you print out the HTML I would include some hidden form fields for each item so that I know what to sort / move up / down. Eg. hidden name="data[item][$i]" value="ID"/ Cimba (hidden ID=3) hidden name="data[item][$i]" value="ID"/ Limbo (hidden ID=1) hidden name="data[item][$i]" value="ID"/ Bimbo (hidden ID=2) Each line would need some sort of javascript command, like javascript="moveup($i)" Assign this moveup() variable to anything, eg. hidden name=check value="**" so we can access it from PHP. Your javascript will then submit the form with ALL variables mentioned above. So do we now know? 1. We have a complete array of all the records from the HTML page in $_POST["data"]["item"] 2. We also know what database ID each item has with the twin array $_POST["data"]["id"] If we were to move something up, now we have a way of doing so, since : Say you entered moveup(2), which the javascript assigned the "2" to a variable "check" which we now know as $_POST["check"]. Moving 2 (Which is 3 since we start counting from 0) we know that 2 is supposed to switch places with 1, meaning the SORTER will be switched. so we know the following : $data = $_POST["item"]; $sourceID = $data["item"][$_POST["check"]]; $destinationID = $data["item"][$_POST["check"]-1]; The rest would be to do the SQL queries for the SORTER field, A=C, B=A, C=B meaning : tempA = select sorter from blabla wher id = source tempB = select sorter from blabla wher id = destination update blabla set sorter=destination where id = source update blabla set sorter=source where id = destination This was all abit quick'n'dirty as I call it, but I hope you got the general idea on how to do it. You need ofcourse alot more debugging and such for the final code (Like you cand moveUP the first row, since that would make the array go from 0 to -1 which doesnt make sence). -- -- Kim Steinhaug -- There are 10 types of people when it comes to binary numbers: those who understand them, and those who don't. -- www.steinhaug.com - www.easywebshop.no - www.webkitpro.com -- "Matt Grimm" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] > I apologize if this message is a repeat; I've had trouble posting with > Thunderbird. > > I'm interested in how you folks would approach the following issue: > > You have a list of data, in a user-defined sequence.

[PHP] Re: form submission logic
Well, I would include another hidden field and name it something like "ACTION". I would also include a checkbox on every item you want to do something with like this : Then use javascript on your actions to set the action to whatever mode you need, for example "delete". On the PHP side you get a very nice workflow now, as you will recieve an array on all the items which are selected and you can perform multiple tasks at once. Example, publish n articles in one go, or delete all at once. Remember to valiudate the $_POST["item"] as an array! Remember, all the values in this array will be the onces you should $_POST["action"].

[PHP] Re: PHP Website Architecture
Well if you really want to do it the perfect way, I would recommend using only one PHP file to generate the whole site. Or if you like, have one file with all the functions. You should also read into classess and create most of the functions as classess. To do the error handling there are many ways to go, but the best way would be to use output buffering. If an error occurs you can store the entire buffer if you like into a database and present an entire different page to the user informing that samoething went wrong. The old alternative is to present a "50/50" page with some error handling here and there. Its really all up to you, there isnt a perfect way in doing this. But my advice again, use classess (OOP) as its very reusable and look at output buffering for total control. -- -- Kim Steinhaug -- There are 10 types of people when it comes to binary numbers: those who understand them, and those who don't. -- www.steinhaug.com - www.easywebshop.no - www.webkitpro.com -- "Paul Higgins" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] > Hi all, > > I have a question regarding website design with PHP.

[PHP] Re: auto saving data in forms
Well shouldnt be a problem. Hook up an iframe on your page, use a javascript timer to send all data to the iframe every n seconds and submit the form inside the iframe. This will give the user a perfect workflow in the window he is working in, since the refreshing and such is done inside the iframe (which can be hidden), Sure you could use javaapplets and such, but there really shouldnt be any need for it. Surely such an autosave function shoudl use a temp database /table to store the data, just as word uses temp files for autosaves.

[PHP] Re: form submission logic
I dont agree however, if your creating a system which should be
user friendly I would absolutely demand from my users to have JS
enabled.
If they dont have JS enabled, then -> well, to bad for them...
We have created several web applications and have alot of
customers (B2B), and they have all JS enabled. The friendslyness
and functionality you can do with JS makes the total experience
far better than not using JS. And you alse can save alot of reloading
of the pages with confirmation dialogs and such.
Anyway, its all a matter of opinion.

[PHP] reversing an IF statement
Often I end up using a "dumb" IF statement which to me seems that
it could have been done some other way.
Example :
if(
($_GET["id"]==1) or
($_GET["mode"]=="home") or
((!isset($_GET["item"])) && ($_GET["mode"]=="news"))
) {
// Here we do nothing
} else {
// This is where we do it
}
If we translate the above to simpler reading we could say :
if(statement)
// skip
else
// Do the stuff
I'm ofcourse looking for this
if(!statement)
// Do the stuff
Problem is, when using more statements I never seem to find the
way of doing it without having an empty {} in it, dont know if you
see my problem here however, its the best I can exmplain.
For all I know it has to be like this.

[PHP] Re: sessions pls help
Well,
What you need to do is start all pages with the session_start(); variable,
like this :
This would make you ready for handling logins and such further down the
page.
What you also need to do is two things,
1. Create a login which registers a new session.
2. Create a validation function which validates the logged user on each
page.
Example, login page :
username=$_GET["username"];
$u->password=$_GET["password"];
session_register(u);
}
?>
The above code would mean that
a)
You enable the session for the page.
b)
If the username and passord is valid, you se the sessionobject, in the
example "u"
to the username and passord.
Further you need the page to validate if you have a valid login, a simple
way would be
to just validate if the u object is something at all, since if you havnt
logged in there isnt
any value here.
Example :
// check if user logged in
if(!$u->username){
// Not logged in, lets throw a header or something to send the user to
login page
}
The best should be to look up the username from $u->username against your
database
to be sure that the username infact is valid.
Final script page would be :
username=$_GET["username"];
$u->password=$_GET["password"];
session_register(u);
}
// check if user logged in
if(!$u->username){
// Not logged in, lets throw a header or something to send the user to
login page
header("location: login.php");
exit;
}
// The rest of page comes here
?>
This is a brief explernation which should give you what you need to get
going on
your session handling. You also might want to add more variables into the
prosess, like IP, browseragent and such to prevent session hijacking from
proxy
servers, just to be on the secure side.

[PHP] Re: export from mysql to csv file
You are also probably using PHPMyAdmin, if not you should be using this.
Exporting to CVS is fairly simple, and if your used to quering the databsae
you should be able to do this very easilly yourself if your looking for a
sollution you can do from scripts.
Basically what you do is simply do a "select * from table", which will give
you
every coloumn of the database, Thereafter loop through the entire dataset
and use the mysql_fetch_array function, then use this :
foreach ($temp AS $key=>$value){
// $key = coloumn name
// $temp[$key] = coloumn value
if(!is_numeric($key))
echo $key . " : " . $temp[$key] . "";
}
Where $temp is the $temp = mysql_fetch_array($dataset_from_query);
If your into >100.000 entries in the database you will need to do some
smart quering, or alter the php.ini to handle more than the standard 30
sec timout. Basically you could also go in "rounds" of limit 0,5
thereafter
limit 50000,5 but that wasnt your question.

[PHP] Re: array_rand() not random
Hmm... Ive been having same problems with mysql and picking random numbers, I ended up having to program a rather more sofisticated system to eliminate the stats you were referring to. You could, not that it will be any better, try another approach : Something like : $count = count($your_data_array); $random = rand(0, $count); echo $your_data_array[$random]; PHP is maby using the same random function for both the array_rand and rand for all I know but its worth a go. The harder way would be to include an internal counter for your elements you want to be randomized, so that when an item is selected you count it. Then the next time you calculate the random element you take the accual hits into meassure. There are like a 1000 ways to do this so use your imagination. One way could be to use some sessions, and when a user hits the page you precalculate the random sort for all your elements, and store that in the session. Then for each and every visit form that visitor you just go along with the pre-randomed data. This way your user will get a truly randomized experienced, and youll be showing off all the elements even if the random function in itself is abit "non-random". Im sure there also exists a mathematical approach calculating a sort of the elements based on the earlier views (meaning that we count each view). -- -- Kim Steinhaug -- There are 10 types of people when it comes to binary numbers: those who understand them, and those who don't. -- www.steinhaug.com - www.easywebshop.no - www.webkitpro.com -- "Nori Heikkinen" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Re: Best Lossless Hi-Res Photo Storage with PHP
well, there are formats that have impressed me. The Mpg-4 format which requires plugins all over the place is really amazing, from e-vue. They also provide a plugin atleast for IE to browse the images. I dont know if you can compress images outside the windows platform however. If your looking for supreme quality however, you would need to stay away from the lossy formats and probably go for TIFF which is a great format and is also supported by any major software. PNG however is abit "strange", woudnt sendt PNG images to a publisher... You could ZIP the TIF images on the HD to same space, you often get good results on this. This would also make the downloads better for the user, and since all the browsing online would use thumbnails you dont need to waste CPU do depack the images, since you all users can depack a ZIP file (thats the least you would expect from a user that purchase a High resolution image). Ive created such systems myself, and my sollution was another : Plug in a new harddrive. We save the images as jpg, tif, eps, ai or whatever the original image was created as, and create thumbnails at various resolutions in high compressed jpg for fast browsing. Often I tend to ZIP the lossless images aswell, but then again I dont need to since HD isnt a problem atleast in my case.

Re: [PHP] Re: Best Lossless Hi-Res Photo Storage with PHP
Hei, Regarding the jpg compression, we did some testing along with our customers press buereu's (I think thats the name, the ones that do all the prints and designs the logoes and such). Here we did som testing on the images and the quality. What we experienced was that if we converted the images to JPG with a quality of 10 it was good enough for most people. I however still use 11 just to be safe. (We are ofcourse talking about >300DPI images) So there you have it, quality 10 is still good enough quality for print. However - be aware of another stupid fact - people expecting high resolution downloads wont download a 4-5mb jpg image, since it cant (?) be good enough quality... They are simply expecting a 50MB tif image since this is what they are working with normally. This is infact a huge problem! So much depending on you customers, but saving as a jpg should be just fine. -- -- Kim Steinhaug -- There are 10 types of people when it comes to binary numbers: those who understand them, and those who don't. -- www.steinhaug.com - www.easywebshop.no - www.webkitpro.com -- "Galen" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] > On Jun 12, 2004, at 4:36 PM, Kim Steinhaug wrote: > > > well, there are formats that have impressed me.

Re: [PHP] Re: array_rand() not random
Well,
I must admit Im gotten abit to familiar with the use of MySQL lately,
though it might be abit overkill - but what the heck. The database is
there to be used and we shouldnt worry to much. For those really
worrying there are several file based "sql" alternatives out there.
Ok, I would use and update statement against the SQL database,
soething like :
update my_stats_table set counter=counter+1 where id=1
All you need is to fire this query on every page, well, you might have
different counters for different pages I just used the ID=1 as an
example, it might aswell be "page='frontpage'"
If you need a more dynamic sollution, meaning you have contents that
you want logged that change from time to time - and you do not
want to prepare the database all the time you could do it like this,
remember
I use a DB extraction layer function named query, so whenever I write
query I really mean mysql_query... Assuming your counting banners
query("update my_stats_table set counter=counter+1 where id=" .
md5($bannername));
if(!mysql_affected_rows)
query("inserted my_stats_table (id, counter) VALUES ('" .
md5($bannername) . "',1)");
You see the logic with the mysql_affected_rows. Now your still stuck with
doing
some nifty stats generating from the data you have in your table - but now
you have
numbers in the database and you have several options.
One that suddenly comes to mind, is always showing the one with the smallest
impressions.
$result = query("select * from my_stats_table where order by counter limit
1");
You would here need to add more information, probably might aswell include
the entire
banner in the database.
Well, BTW, hope this helps you.

that would be cool. but how do you maintain the value of a counter
from reload to reload? would i have to open an external file, read
its variable, increment it, write to it, and close it every time? or
is there a way to do that in the code of a single php page?

Well, there is really a short answer for this one. NO! I guess you want to inform the user that a 30MB file is to much to handle for the default 2MB barrier of PHP. Uploading the 30MB file to inform the user that 2MB is what we can handle is kinda to late.. Ive been looking several times for systems that can tell me the filesize before I upload the files / images. Javascript doesnt have the rights, maby some javaapplet where the user accepts the applet could do it.

Do you really need to use stripslashes when retrieving the data?
Wouldnt stripslashes only affect magic quotes or already added slashes,
I mean when you addslashes to the SQL the slashes are indeed removed

Man - did their staff get a lot of support from people who didnt manage to logg into the system...

I know for a fact one large provider here in Norway who has this problem on one of their servers due to a heavy site which from time to time sucks up resources resulting in the /tmp folder getting messed up.
