[PHP] Re: Regex
If what you mean is a db table, then it would seem to me that you should
not be using a regex. PHP has rawurlencode() for this sort of thing.
But - you should learn regex ;-)
Try something like (untested and late at night)
function urlme($location)
{
$enc=rawurlencode($location);
$spc=htmlspecialchars($location);
return "$spc";
}

You don't know Regex. Well, that's simple then, TRY to learn it. Noone
will (or should) give you any answers if it's absolutely clear that
you're not putting any effort into trying to find one yourself. "I know
this should be done using Regex, but I don't know regex.", wouldn't you
think it'd be a good idea to look up a tutorial somewhere or try to find
out what this "regex" exactly is? Try to type regex in the php doc, see
the notes for the various functions?
really, a little more effort goes a long way.

Re: [PHP] Overriding core functions
It may be possible to override the core function - I don't actually
know. If you just define a new function with the same function it might
work OK.
The snag I see coming at you like a tonne of bricks is 'how do you call
the original function once you have overridden it.'. This like like
calling SUPER. in Java.

[PHP] Re: Why small > big?
M Sokolewice got it nearly correct. However, the situation is a little
more complex than he has discussed.
The % compression figure for jpeg is translated into the amount of
information stored in the reverse cosine matrix. The size of the
compressed file is not proportional to the % you set in the compressor.
Thus 100% actually means store all the information in the reverse
cosine matrix. This is like storing the image in a 24 bit png, but with
the compressor turned off. So at 100% jpeg is quite inefficient.
The other issue is the amount of high frequency information in your
images. If you have a 2000x2000 image with most of the image dynamics
at a 10 pixel frequency, and you reduce this to 200x200 then the JPEG
compression algorithm will 'see' approximately the same amount of
information in the image :-( The reality is not quite as simple as this
because of the way JPEG uses blocks etc, but it is an easy way of
thinking about it.
What all this means is that as you reduce the size of an image, if you
want it to retain some of the detail of the original but at a smaller
size, there will be a point at which 8 or 24 bit PNG will become a
better bet.

Re: [PHP] Re: Why small > big?
mention is probably the discrete cosine
transform (DCT) matrix where the x, y pixels of an image file have a z
component representing color. From that you can translate the data into
the frequency domain, which actually generates more data than the original.
However, the quality setting is where you make it back up in compression
ratio's by trimming off higher frequencies which don't add much to the
data. Unlike the FFT, the algorithm does not address phasing, which I
found interesting.
However, the answer to my question deals with the quality statement. In
the statement:
imagejpeg($image_p, null, 100);
I should have used something less than 100.
I've change the figure to 25 and don't see any noticeable difference in
quality of the thumbnail.
It seems to me there should be a table (or algorithm) somewhere that
would recommend what quality to use when reducing the size of an image
via this method. In this case, I reduced an image 62 percent (38% of the
original) with a quality setting of 25 and "see" no difference. I think
this (the quality factor) is programmable.
As for png images, I would probably agree (if I saw comparisons), but
not all browsers accept them. I belive that at least one IE has problems
with png's, right?

[PHP] Re: ssl.
It would appear that the root of the page has not gone back to http. Is
it possible that this is a one of those cases when two things get
changed at once by accident?
I would suggest downloading the IE developer's tool bar (or the firefox
equivalent) and then when you get to the page you think should be http,
but is sticking on https, view the DOM. By carefully going through the
DOM there is a good chance that you will find that, for example, the PHP
you have redirected to http is indeed running in a frame or some such.

Re: [PHP] ssl.
João,
Surely the issue is to find why it is not working now. Why it did work
in the past is only of interest if you want to stop the problem
re-occurring in the future. Thus, the correct approach is to find why
it is not working now, fix it and then see if you can work out what has
change between the past and now.
It is just possible that changing the key length has resulted in a
different connection encryption escalation process between the server
and the client. I am a little rusty on this :-( However, if that is
the case, I would suspect that what you are seeing is a bug that has
always been there but did not show up before. This might revolve around
which port is being used (as you can map both https and http to one port
if you use escalation - or at least I seem to remember that is possible
with TLS).
In summary, find out what is broken now and all will be clear. To find
out what is wrong now you should find out the exact structure of the
returned page.
Good luck

This shouldn't have anything to do with the certificate.
It most likely has to do with something being loaded on the exit page that
is not secure. For example, if there is a hard coded link to an image, or
an included javascript link to an outside source.
If anything on the page is not secure, then you will get that error.

Re: [PHP] ssl.
João,
Please try and find out why it is not working now. Once you have that
worked out, it will be much easier to find out what has changed.
There are a few subtle methods by which changing the key length might
interact with PHP. However, in general, PHP is not involved with the
encryption of the socket. It will be near impossible to guess what
might have gone wrong. It will be much easier to work it out once you
know the structure of the page that is causing the trouble.

this is also the part, that João get confused by ;)
He says that everythign works fine until he leaves the secure site.
Maybe the notice got shown before the change of the key to 256kb, and
get accepted to not show again in the future. Now after the change the
notice come again because it is a 256 key instead of 128kb. I don't know
if IE makes a difference in that

[PHP] Re: functions classes
Bigmark, I have been involved in the evolution of the development process and architecture called functional normalization. I do intend to post some detail on this at funkifunctions.blogspot.com very soon. Anyhow, using this method might help you some what. The trick being to look through your script and see if the same thing is being done in more than one place. For example, if you find a piece of code that converts a string into a URL and that piece of code is REPEATED through thes script, then place that code in a function and replace the instance of the code with function calls. Over a period of time you will see more and more of your code turn into functions. Once this process has started you will be able to predict to some extent what new pieces of code could be re-used in this way and hence write them as functions also. This approach has proved to be extremely successful in advancing the careers and coding practices of developers inside and contractors to the project network (www.project-network.com). If you would like, I am very happy to take a script from you and convert it over to functions. I will also let you know when more material on FN is posted to the blogsphere. As for classes. I would recommend avoiding thinking about these yet. Function level re-use is a better start discipline that class level re-use IMHO. I know this is an contentious issue. Having been an avid OO programmer for many years I have evolved away from this, other people have different views (yes really, I did a lot of OO work with Java/Weblogic/C++/iTCL etc etc etc - please don't flame - not interested!).

[PHP] Brain Death - [PHP] functions classes
I don't know what I was on when I wrote the previous post!
In php you cannot create static class variables in this way (doh) or at
least I never have managed. So when faced the this problem I replace
what in C++ would be a class variable with a class function
comme ca:
class MyClass
{
function MyVar($val = null)
{
static $datum;
if(is_null($val))
{
return $datum;
}
$dataum=$val;
}
}
I definitely need more coffee!

RE: [PHP] Brain Death - [PHP] functions classes
Rob,
I'd go along with the setting a var to null issue (in the cases I have worked
so far on, there has not been a need to set variables to null). However, what
is wrong with is_null()?
>From the php manual chm:
>>>>>
(PHP 4 >= 4.0.4, PHP 5)
is_null -- Finds whether a variable is NULL
Description
bool is_null ( mixed var )
Finds whether the given variable is NULL.
Parameters
var
The variable being evaluated.
Return Values
Returns TRUE if var is null, FALSE otherwise.
<<<<<
And to be very pedantic - as null does not have a type then actually 'x ===
null' should evaluate to absurdity, but PHP is more pragmatic than that ;-)

Talking about coffee... your above code could use some. Try this:
But also I'd recommend fixing the the problem whereby you
can't set $datum to the null value, otherwise you may run
into unexpected issues down the road.

RE: [PHP] Brain Death - [PHP] functions classes
Right or wrong - C does not actually have NULL :-) NULL in C is simply mapped to zero. It is useful in logic to sometimes use mapping of logical sentence letters to numbers and use mathematics to perform proof, but that is a special case. In languages like C, there is no special method of marking a variable as true NULL. Thus, the language has no way of processing three state logic. In SQL, there is a special flag to note that variables are truly null and so it can process three state logic. PHP is odd because it does have a special NULL state but it does not fully support three state logic. But hey - it is a web scripting language - it would be a shame if PHP got all theoretical on us! BTW: >Rome... Oh btw, PHP draws strongly from C, and in C NULL == NULL, and NULL == NULL === TRUE It is NULL === NULL == absurd. So - my approach: I may well use is_null() in low traffic areas on PHP, but then when in an inner loop etc, use === null and maybe comment what it means.

My reasoning is simple and I don't strongly agree, or disagree, with other methodologies. I write in several languages, such as php, js, mySQL, css, and others -- and each have their own constructs. As such, I try to use similar constructs where ever possible. My memory isn't what it used to be. Besides, what Alex Turner said about NULL is correct -- it's absurd to have NULL evaluate to anything. Just because one language allows absurdity doesn't mean you have to practice it. Your mileage may differ and that's Okay. :-) tedd -- --- http://sperling.com http://ancientstones.com http://earthstones.com -- No virus found in this incoming message. Checked by AVG Free Edition.

Hi,
This is really odd. I use this code to retrive value from a database table.
When the field is empty, it cracks the HTML code some how, the PHP script
seam to not break.
function getInfo() {
$html = "";
$html.=
"Name".$this->getName()."";
$html.=
"Description".$this->getDesc()."";
$html.=
"Priority".$this->getPriorityText()."";
$html.= "";
return $html;
}
The function getDesc is like this (I have made it overly complicated because
I am trying to fix the problem):
function getDesc() {
$Query = sprintf("SELECT todotext FROM teamtodo WHERE id=%d
LIMIT 1", $this->getID());
$Result = mysql_query($Query);
if(mysql_num_rows($Result)>0) {
if($Roww = mysql_fetch_array($Result)) {
if($Roww['todotext']!='') return
$Roww['todotext'];
else return '';
} else return '';
} else return '';
}
When the database field is not empty it works fine, but as soon as the field
todotext is empty the $html seam to break, but the value of $html until the
$this->getDesc() is still being returned by the function (can see half of
the table).
Is this a bug, or am I just stupid? If I just insert some blank spaces it
works, hrm.

Peter, When it arrives at the browser, via ajax, I am guessing that you then put it into the page view .innerHTML or some other method. I suspect your problem revolves around asking the browser to do stuff it should not really have to do. There are two issues I would like to highlight with the html. 1) You are mixing TH and TD on the same row. You should be using styles to set the different presentations of the elements. 2) You have placed a paragraph section between the table tag and the first tr tag. This is wrong. I suspect that the browser is managing to cope with this markup when presented as a static page but is unable to figure out how to update an existing page with it. If you fix the html to be standards compliant then the chances are all will be well.

But it would be much better to use the output buffer to append a chunk of characters to the whole page and then md5 that. This makes it much less likely that a snooper could bruit force attack the system. The next stage beyond that is just to AES encrypt the whole communication. As you have access to both ends, there is no requirement for asymmetric cryptography. Then simply put a known phrase as the start of the request then the other end checks for after decryption and if it is not there it rejects the message. Crank that up to 256Bit encryption and you have a commercial spec system :-) Cheers AJ PPS as MD5 is now part cracked, if you are truly paranoid, use SHA. -- www.deployview.com www.nerds-central.com www.project-network.com -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] Re: IE session problem on one server only
Larry Garfield wrote: Another issue. :-) I've another site I've built that uses PHP sessions for user authentication. When the user logs in with a user/pass, that is matched against a record in the database and, if found, that user object is stored in the session along with various other tracking data like the IP address, and the session key is stored in the user table. Then when viewing a page, the systems compares the session key against the user table and the IP address of the request against the saved IP address. If anything doesn't match up properly, the user is kicked out. OK, all fine and dandy. It works correctly in both IE and Firefox on our test server. On the live site, however, it works only in Firefox. In IE, it accepts the initial login and displays the first page, but then the next time the user clicks a link they are asked to login again, as if the session is not being sent or saved properly. Both servers are running Linux and PHP 4.3.x. We had issues before with the session not working correctly in IE, but I fixed those with info from the php.net manual user comments. I'm at a loss as to why it's only happening on the one server and not the other now. If it were the other way around I wouldn't care, but the live site shouldn't break. :-) Any idea what could be the problem? It sounds like the IE is putting different security/cookie settings for your local and remote site.

[PHP] Re: How would you do this ?
Jad madi wrote: I'm building an RSS aggregator so I'm trying to find out the best way to parse users account feeds equally so Lets say we have 20.000 user with average of 10 feeds in account so we have about 200.000 feed How would you schedule the parsing process to keep all accounts always updated without killing the server? NOTE: that some of the 200.000 feeds might be shared between more than one user Now, what I was thinking of is to split users into 1-) Idle users (check their account once a week, no traffic on their RSS feeds) 2-) Idle++ (check their account once a week, but got traffic on their RSS feeds) 2-) Active users (Check their accounts regularly and they got traffic on their RSS feeds) NOTE: The week is just an example but at the end it’s going to be dynamic ratio so with this classification I can split the parsing power and time to 1-) 10% idle users 2-) 20% idle++ users 3-) 70% active users. NOTE: There is another factors that should be included but I don’t want to get the idea messy now (CPU usage, Memory usage, connectivity issues (if feed site is down) in general the MAX execution time for the continues parsing loop shouldn’t be more than 30 minutes 60 minutes) Actually I’m thinking of writing a daemon to do it “just keep checking CPU/memory” and excute whenever a reasonable amount of resource available without killing the server. Please elaborate. I would suggest using a queue/pool system. Have one mechanism the loads request for update into a queue and anther that takes the requests out of the pool at the fixed rate (or several at once over different threads/processes). You then limit the rate the messages are consumed to the maximum you want the server to use up. You can then add update requests into the queue based on how often the user checks their feed. That way, the more often they check it, the more often it is updated. OK - this needs a bit of polishing, but I suspect it would do what you wanted. A database table would make a nice queue as you insert at the bottom and read/delete off the top and let the DB engine synchronize up the separate threads of action.

[PHP] COM Dlls not unbinding
Hi All,
I am doing a lot of PHP work with COM. The system uses php 4.3.3.3 and php is
being driven via FCGI from our own web server (TAG).
We create an instance of an in-process COM server using the following technique:
function GetFactory()
{
static $obj;
static $objSet = 0;
if($objSet==0)
{
$obj=new COM("TPN_Obj.JDCom_Factory");
$objSet=-1;
}
return $obj;
}
The returned COM object is then used as a factory to all our other COM objects.
The snag is that the binding to the COM dll is not being released at the end of
script execution. This is visible using ProcessExplorer from SysInternals.
If I call com_release the returned ref-count is zero. To ensure that php's
garbage collector was not the culprit, I tried repeatedly calling com_release
at the end of the script - no change.
The upshot of this issue is that each PHP process in the FCGI process pool
gradually gets bigger as more and more dlls are bound :-(
Any ideas are welcome; I have gone through the php source but cannot quite
figure the problem. Changing the C code is OK for our application.
Thanks!

Re: [PHP] Managing upload files in multiple servers(pawns)
Why not use php to copy the file over to the other box? You could do this either by ftp, nfs etc, or by making a the php script communicate with the upload script on the other box as though it was a client. Cheers AJ Srinadh Sannidhanam wrote: Thanks Duncan, thanks for the suggestions, I will try them and come back.. Please suggest me if you know any file synchronization tools over different servers other than rsync. I like if syncronization triggers immediately after uploading the file automatically rather than using cron. Thanks, S.Srinadh.

There is a page in the site through which user can upload images. When a user uploads an image, the request goes to only one of the two servers. So the image will be uploaded to only one server. Use a shared file system such as NFS for upload storage. Use some form of session management/balancing that ensures a client browser that upload ends up on the same server immediately afterwards, and use something like rsync to keep the image area in sync. Shared storage is probably the better bet - perhaps with clever code that tries a local disk first, then the shared storage if not found on local. If found shared and not local, pull to local. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
