I maintain a mixture of Linux, FreeBSD and Win2k servers. I know a lot about the
Unix platform, it's structure and it's pros and cons. However, once again you
have made several claims about how it is 'better' than Win2k but without
evidence to back them up.
Why is Unix more flexible? I can't think of anything I can do on Unix but not
on Win2k. Why is it more secure? I have been running several Win2k servers for
nearly 2 years and am yet to have a major security problem (I am certain that
the reputation IIS has gained in relation to security is due to incompetent
admins, not the product - a side effect of making it relatively easy to
configure). Why is it more stable? Since Win2k was released I have managed
uptimes comparable to the Unix-based machines I maintain.

How many BSODs have I seen on any Windows box? Loads. How many have I seen on
the Win2k servers I maintain? None!

'It has a real file system'. Meaning? I assume you mean ext2 which is a
non-journaling and therefore highly fragile file system. Compare this to NTFS
which is a journaling file system. The performance loss by adding the
journaling is minor but has major benefits.
Hmmm, the GUI. You mean the one that shows the login screen? That tiny stub
that takes up virtually no resources while it is waiting for a user to log in?
What you have said is like saying "don't install KDE on your server, it will
take up valuable resources whether you use it or not".

I am a successful sysadmin (at least my customers think so) and I do provide
the best 'possible service / speed and uptime' on both Unix and Win2k
platforms. Suffice to say that you are yet to convince me.

What gave you the impression that I need help? I butcher and build machines
every day, but even if I did need help, I would be reluctant to accept it from
someone who can't spell Perl and doesn't even understand the purpose of /tmp on
the Unix platform.
> Nuff said.
Not quite. I would just like to say that I don't preach that either platform is
'better'. It all depends on the job in hand and I will choose a platform based
on my requirements. I would certainly not base my decision on the
foundation-less spoutings of someone on a mailing list (that includes me,
although I am trying to walk the neutral path). My only hope is that people
will stop dismissing one of the options because of a bad reputation that was
created many moons ago and will therefore take a while to counter.

I am planning to change how my site stores logins to using sessions.
Are there any reasons not to do this? Reasons against it I should
know? Thanks for your input.
--- End Message ---

How is it currently storing it?
Sessions are fine, depending on how the code is written, and the obviouse
downside to COOKIE based sessions is that they will break on non-cookie
browsers, so a smarter move is to use URL based sessions.
A more focused question will of course result in a more focused answer :)

I'm currently storing the username and password directly in cookies (the
password isn't even md5()'d). I'm just wondering if there's security
risks/whatever in sessions. I've seen that most sites seem to store the
login data directly in the cookie (with the password md5()'d). Is that
because there's something wrong with sessions, or did they just not use
them for no reason? Thanks.

As a general rule it is always good to store data that is secure in a encrypted
format. My website for example uses a mysql database and I store the encrypted mysql
password in the cookie so I get somethign like 435gcg34tsskhj57 to equal 123. It's
far more secure because cookies are on the user's computer and anything there is not
secure, regardless of who the owner is.

Well, all passwords on my sites are stored md5'd, so i'm comparing an md5()
of the password they have supplied with the one stored in the DB, so I don't
need to know what the original password was -- only if the two encrypted
passwords match.
Since md5() is one-way encryption, it makes sense to store the password in a
cookie this way as well, so that people digging around can't possibly figure
it out.
I guess leaving the password in plain text in the cookie opens a small
security hole which is unneccassary, as long as you're storing an encrypted
password in the database.

I know it has nothing to do with filesize because I am the server and I set the
configuration. But lemme show you some code, maybe that'll help. Here we go:

All that is included within a main program and when you send data out from this it
gets looped back into itself with the global statements, that's the idea anyway.
However, $File_name always turns up null, (as well as the other operators) which makes
uploading not possible.

-Lakario,
Please have a look on
http://www.php.net/manual/en/features.file-upload.php for more information
on fileuploads in php.Also check with the size of the files you have
transferred.When file size is large, then your files won't get uploaded.This
is due to the low execution time,If you don't mind please send your programs
to dig more.

Subject: [PHP] Confusion with the $_name $_type $_size Variable Extensions
I am having a lot of trouble with the $_name, $_size, and $_type
variable extensions. I have a basic file upload system however it is
within a function. Sometimes when I declare the aforementioned
variables in a global statement such as global $file_name I can get a
value for _name, other times, I get nothing. Can someone clarify
this because I was unable to find anything in the manual?

Hmm, I haven't heard of such a thing. That's kinda weird though because just yesterday
I modified my timeout settings for my script that parses logfiles that are several
thousand lines long, and it worked. Did you perhaps forget to reboot the server? If
you have my suggestion is perhaps taking a look at FoxServ, it is a very good server
that auto configures itself on your machine with apache and the whole lot.

I think you'll find that's the IIS CGI timeout, not PHPs. You can find that
setting in the site properties, Home Directory tab, click on the Configuration
button, then go to the Process Options tab. At the bottom of that tab you
should have a CGI script timeout value. Try increasing that.

Hi,
indeed, it is a IIS CGI timeout. However, when I take a look at the tab you
gave me, I can only seem to find the tabs called "App Mappings", "App
Options" and "App Debugging". Is this the right place and is the tab just
missing or is there a problem on my behalf?

not there then I suggest you search the MS site for help.

hi, thanks for the code. i tried. it only worked if the string is simply
the one i wanna convert. but that particular string is in the middle of
a long text, and there are multiple occurance, it won't.
however, i did manage to come up with this code that worked. but i
believe it can be improved on. it will identify all occurance of the
specified pattern and do the necessary replacement throughout the whole
string.
preg_match_all("|\[::(.*)::\]|U", $longTxt, $matchedResult);
for ($idx = 0; $idx < count($matchedResult[1]); $idx++) {
$extract = stripslashes($matchedResult[1][$idx]);
$longTxt = str_replace("[::{$matchedResult[1][$idx]}::]",
"\".$extract.\"", $longTxt);
}

Strange. It should work regardless of length.
Couple things. Could you please provide an example of the text you're
trying to convert and explain why you have this weird format and why
you need the other unusual format. We may be able to come up with
something far more straight forward.

hi,
i was developing an application that will read in the content of a html
file. and within this html file contains php variables which will be
replaced using the eval() function with its required value. and within
this html, i want to be able to run php functions. however, due to the
fact that characters need to be escaped so that eval() can process it, i
have to make use of addslashes() to escape all " that are embedded in
the html file.
with the " escaped, eval() will be able to work and evaluate the php
variable and instead of:
eval("\$rs = \"<span class="normal">$phpVar</span>\";"); (won't work)
it will now be:
eval("\$rs = \"<span class=\"normal\">$phpVar</span>\";"); (work)
and to call a date() function on the above text, this format will work:
eval("\$rs = \"<span class=\"normal\">".date("m d y")."$phpVar</span>\";");
since the text that is passed into eval() came from a html/php/inc
(whatever you name it) file, there is no way you will know that a
particular text is in fact a php function.
so i thought of prefixing and suffixing php function with [::date("m d
y")::] and it will be helpful in the sense that the application will
know that oh, this is a php function, i need to ". ." it so that eval
will not throw me an error.
with that, now the html file's content will be something like:
<span class="normal">[::date("m d y",$phpVar)::]</span>
after using addslashes(), it will be:
<span class=\"normal\">[::date(\"m d y\",$phpVar)::]</span>
for the above text, in order for eval() to parse correctly, it has to be
in this format:
eval("\$rs = \"<span class=\"normal\">".date("m d y",$phpVar)."</span>\";")
and there is always a chance that the html text could contain more than
1 block of [:: phpfunction ::]
thats why i came up with that piece of code to convert the text to a
string that eval will be able to understand. and at the end of it, i
will be echoing $rs to display the final result.
you probably will wonder why dont i use include() and require()? that
way, php will be handling all the above without requiring additional
work. however, due to the way the result has to be handled, i couldn't
use include nor require.

Prachait,
If I recall correctly, PHP 4.x doesn't work with Apache 2... Actually, no
Apache 1.x modules do, because of the new apxs architechture. Apache 2
support is planned for the 4.3 release (someone correct me if I'm wrong).
On UNIX, I compiled with a -apxs2=[path] option to the configure script, but
I'm not sure on Windows...

There is a module specifically for Apache 2 in PHP 4.2.0 onwards. I'm not sure
what error using the module for Apache 1.3.x would produce. This could be the
problem. The Apache 2 module is still experimental and should not be used in a
production environment.

Hello,
I've inherited a MySQL db (4MB on disk) that's riddled with
inconsistent storage of character entities from being pasted from
Word. At very least I hope to convert all quotes "‘" - "”"
to HTML's """ and "'".
I imagine I'll run a big query, save the id's needing edit in a file
than have a script hit all those, pulling text/varchar fields, using
strtr() to make changes and updating. I suppose I could have the
script just do the 1st 10 in the file, remove those from the file,
then I'd recall the script. I imagine this might take 10/20 minutes.
Am I missing some internal MySQL feature that would do this? Hmm,
what about running strtr() on a mysqldump-ed file? Any advice/links
appreciated. Please CC me.
Thanks a lot!
Steve

For each entity you wanted to replace, you could:
update tablename set fieldwithcrap = replace(fieldwithcrap,
'oldstring', 'newstring');
Keep an eye on all your escaping and what not. And do a dump before
you do all your replacing, just in case something goes awry.
If that doesn't work well, then I'd probably dump the data, run it
through a string replacing script, and load it all back in. That
wouldn't take too long either.

Yeah, do it all with regular queries. You shouldn't have to do any
replacing in PHP. You can even use the MySQL regular expressions in your
query for some more complex matching and replacing...
It's all in the manual...

What is the best way using only PHP to grab a image file off a website a
d save it locally? I know I can use wget and this would be a piece of
cake, but in this case I don't want to rely on external programs.
I'm trying to read it with fsockopen and writing it with fopen to the
file but the file is no good when it's saved, I saw that it saved the
http headers in there so I cut those out but still, the image wan't
viewable.
I was using fsockopen instead of file because I want to use the timeout
feature of fsockopen.
any help is appriciated.

Are you using the binary safe fread/fwrite()? Didn't forget to fclose()
the output file?
This works for me:
<?php
if($fi=fsockopen("host",80))
{
fputs($fi,"GET /image.gif HTTP/1.0\r\n\r\n");
while(!preg_match("/^\r?\n$/",fgets($fi,1024))); //skip headers
while(!feof($fi))
{
if($fo=fopen("/tmp/tmp.gif","w"))
{
while(!feof($fi))
{
fwrite($fo,fread($fi,65535));
}
fclose($fo);
}
}
fclose($fi);
}
?>

Hi Everyone,
Any idea why I'm getting this error?
Warning: setcookie() expects parameter 3 to be long, string given in *my
script* on line 2
Here's the entire script generating the error:
<?php
setcookie("mytest", 1, "", "/");
?>
The script doesn't work on a new hosting service I subscribed to, but it
works on two other servers - 1 linux and 1 windows, both with Apache 1.3.24.
I'm looking for what version the hosting service is using... their support
page says "PHP4 with Zend Optimizer". The other two servers are using PHP
4.1.1.
Any ideas of what's going on?

It needs the time to be something not null. If you mean to set 0, use
"0" instead of "". Or, time()+somenum (not in quotes).

Hey all,
I am in the middle of writing a script to allow users to search through
news archives on my website. Anyhow I am just wondering which logic you
believe best suits a search.
i.e. say a user types in 'games AND playstation' then only results
containing both those words will be returned
by the same token they could type in 'games OR playstation' then results
containing either word will be returned
However if a user does not explicity join there search critiera
i.e. 'games playstation' what should I assume?
What would you expect? Google for example wacks an 'AND' inbetween which
is wise considering they are searching billions of pages however my site
obviously will only be searching a few hundred so maybe I should assume
an 'OR'?
So basically I just am curious to know what you would expect when
entering multiple critera.
Regards,
Scott

Funny. I asked a very similar question the other day. Jason Morehouse was
nice enough to offer this advice:
If you use fulltext search (assuming you are using MySQL), it deals with
stop
words on its own as well as some additional search logic.

Thanks for your help Everyone =)
I needed the 3rd parameter set in order to specify the fourth "/", because
the cookie is being set by a script located in a sub-directory. One of the
old documents I read said "" would work as the third parameter - and it did
on my old servers. Setting the third parameter to 0 worked on all servers.

I am trying to input data from a text file into a MySQL database and would
like to be able to input the data using a single script. What's the easiest
way to parse a line, such as below, and turn it into variables to be placed
in the database. While I can simply place the data in by importing from a
file, it's not quite so easy. I only need to place some of the data in,
plus I would like to split one of the fields. Below is an example of a line
from the file, and then the variables that I need to enter.
Here is an example of a line from the file:
Number,City,State,Country,Provider,Isdn,56K,CreateDate,Active,Timezone,ModDa
te,ModNote
403 -770 -4904 ,CALGARY,AB,CAN,T2,Y,Y,Apr 29 2002
12:00:00:000AM,I,GMT-0700,,
As for variables, I need the following:
Split Number into $AreaCode & $Number > 403 & 770-4904
$City
$State
$Country
Thanks for any help.

Hi All, Hope you are all well.
I am coding a website for a client and they involve a series of files:
logobanner.php
navbar.php
leftmenu.php
main.php
rightmenu.php
copyright.php
These are all just simple HTML files which are placed in a Global dir apart
from main.php which is in the same dir as the index.php file. Is there a way
where I can have one index.php file which calls all the Global files and
only the relevant main.php file? Kind of like a simple template system?
For example at the moment I have this for my dir pattern:
/global/
-logobanner.php
-navbar.php
-leftmenu.php
-rightmenu.php
-copyright.php
/home/
-index.php
-main.php
/news/
-index.php
-main.php
When /news/index.php is called, all the global files are called along with
the main.php that is in the News dir, the same for all the others in their
respective dirs.
Am I overlooking an important function or script that can do this without
being too complicated?
Please let me know, Ian.
