[PHP] Quick question regarding debugging and PHP structure.
Short: Is it possible to see the PHP code that is going to be processed in whole? Long: I love to see things visually, and while programming i create all kinds of debugging variables i keep on the side for each page/request. I know this is possibly not possible since this has to be done from either the Zend Engine or PHP itself, but if i could see a complete output of all the code within my project that is used for a certain execution. Example: I call index.php?page=10 index.php includes functions.php and classes.php classes.php include page_classes.php if there is a $_GET[page] variable set and product_classes.php if there is a $_GET[product] variable set What i would like to see is the linear output of what code is included (so the data of functions.php, classes.php, then page_classes.php, and then index.php (not product_classes.php since its not included within this request) This is most likely possible with some PHP code but I'm thinking of trying to make sense of an old project i didn't create quickly and if this is possible it would help a lot. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] still can't get a login with session working ... is there another way to mask the url parameter?
1st. Replace your $sql query with this
$sql = sprintf(SELECT * FROM admin WHERE UserName = '%s' AND Password
= '%s', mysql_real_escape_string($UserName),
mysql_real_escape_string($Password));
$result = mysql_query($sql) or die(mysql_error());

I am sure about the presence of the white color in the background

a similarly simple test setting transparency on a new image created

And thanks for the reply also Ashley but as i said in my first post, i had tried $_SERVER with limited results If checking the output of phpinfo() doesn't help (and it looks like it won't), I'd suggest starting with REQUEST_URI, then, if you know where your webroot is, you should be able to calculate the path to the target directory (/var/www/example/../test/ in your original example) by gluing bits of path together. Hardly an ideal solution as it needs configuration, but it would work. I think this is really a mod_rewrite problem, as by the time PHP takes over you've lost the information you need. You may have better luck in a forum devoted to mod_rewrite, but I'm not optimistic that it has a what file would have handled this request if mod_rewrite hadn't run parameter. I think you're going to have to build your directory path from the information in the original request and some configuration glue.

Re: [PHP] Problem with script timing out in php 4.4.8
Could you try setting the max_execution_time with ini_set and
confirming the status of it with ini_get ?
- Waage
2008/6/4 Arno Kuhl [EMAIL PROTECTED]:
I recently picked up an issue when I upgraded my IDE, where the browser
window timed out while I was debugging the code. I checked with support and
was told the problem was with php 4.4.8 which they'd upgraded to, so to
confirm I installed 4.4.8 and ran a test - and it seems there is a problem
with 4.4.8.
The test was:
change max_execution_time from 30 to 600 in php.ini - phpinfo confirms
max_execution_time=600
?php
$t=70;
echo h2Test timeout - sleep for $t seconds/h2;
echo sleeping .date('h:i:s').br /;
sleep($t);
echo stop sleeping .date('h:i:s');
?
$t=59 works fine, but $t=70 times out.
(Windows 2000, Apache Release 10324100)
I ran the same test successfully with $t=500 seconds on a different machine
running php 4.3.4, everything else the same as the original test pc.
What bothers me a bit is 4.4.8 has been available since February and
checking the archives I see no-one else has reported this problem, which
seems highly unlikely, so I'm wondering if this is specific only to my
environment somehow. Has anyone else had problems with max_execution_time in
4.4.8?
Cheers

i have a registration page where a user enters their username and if this

after adopting the technique to avoid sql injection
if(get_magic_quotes_gpc())

else

$username = $_POST[username];

previously my select and insert query were
INSERT INTO individuals(username, email) values('$username', '$email')
Select username from individuals where username = '$username'
presently the insert query is
$insertquery = sprintf(INSERT INTO individuals (username, email) VALUES
('%s', '%s'),

This insert query is working however the select query is not doing its task

register with the same username again it does not alert that the username
exists.
the select query is
$selectqueryusername = sprintf(Select username from individuals where

should i change the syntax of the above select query or is there something

if i run this script using php -f test.php it works fine. However if i try
and run this on my loca apache server i get the following error:

As you can see from that error i am using windows and apache 2.2. My php
version is 5.25. I have Registered Stream Socket Transports tcp, udp, ssl,

I suspect that you are giving a very short timeout but then you are not
handling the timeout error properly.
Anyway, before reinventing the wheel, you may to try this HTTP client
class that supports many options including establishing SSL corrections
and setting and handling timeouts correctly.

Re: [PHP] client time zone?
To get the clients time offset you'll need to use javascript and date.getTimezoneOffset() But this idea has a problem. It is that you can never trust that the clients time is actually correct. You can get the closest to it by using the server time and offsetting that with the javascript offset value. But you'll never know if the client has the wrong timezone and you'll have to deal with timezones that don't have daylight savings like for instance Iceland :) - Ólafur Waage 2008/1/6, Per Jessen [EMAIL PROTECTED]: jekillen wrote: Hello; I am running a server that is using UTC and I want to be able to convert to clients local time in some display presentations.

Re: [PHP] image* Functions' Memory Usage
I recently made two commercial sites that used both GD and Imagick and i can share some wisdom i got from those projects. (both projects were card generators where users made their custom cards and but one had a fixed picture and users could add text and the other one allowed users to add their own picture with text) # Some functions of the GD library are VERY memory intensive. For example the image resizing. The resizing process is calling three functions to work and two of them are holding very large amounts of data within them. (the original image and the new image area you are going to put the resized image into, and then the 3rd functions resizes the image) # Basic GD library functions can be quite fast (and most if not all Imagick functions are fast if the image isn't too big) # Speed of both options are always affected by the size of the image being used. (Size in bytes, a 10x15 print quality card generated with a user selected image + text can take up to 30 seconds to generate) And yes thats an annoying generator to debug. # If you are going beyond simple things like adding text onto an image i recommend going with Imagick. # Imagick is a great system to use if you learn all the command lines and combinations, far superior to GD in many ways. # Complex Imagick functions (that works with all possible outcomes) can be VERY slow. # If you have the choice of running Imagick from the command line (installed onto the linux system) or running the Imagick PHPlib, go with the PHP library one (even though it looks like more overhead in code) since error reporting with the command line is close to none. # If you have the choice of the images being generated later (ie. by an admin of the system), go with that path always. (one of my systems does that and the other doesn't) and the problems with the end users on the image generating step are very hard to debug, since they usually describe the problems very badly. Hope this helps some. - Ólafur Waage [EMAIL PROTECTED] 2008/1/4, Casey [EMAIL PROTECTED]: Greetings, list.

Off the top of my head. This wouldn't allow for using the right angle

Re: [PHP] preg_match_all to match img tags
Guys i would like to thank you for the help.
Jan i used some of your code to help me get this. There was one issue
with yours, preg_match_all while in a foreach will only match the last
match and output that as the $m array.
Here is the code, i hope someone else can use it. Its a working code
in PHP4 and PHP5. I am currenly wrapping the imageManip(); around the
$_POST variable that is the blog post when im posting it to the SQL.
So the getimagesize(); only has to run once.
There is one bug, if the user resizes the image manually to something
less than 590, to say maybe 400, this program will still resize it to
590.
function imageProportions($image)
{
$imageLoad = @getimagesize($image);
// if the image is larger than 590 pixels, it will resize both
height and width
// if not it will do nothing to the variables.
if($imageLoad[0] 590)
{
$proportion = $imageLoad[0] / $imageLoad[1];
$imageLoad[0] = 590;
$imageLoad[1] = $imageLoad[0] / $proportion;
return array($imageLoad[0], ceil($imageLoad[1]));
}
else
{
return array($imageLoad[0], $imageLoad[1]);
}
}
function imageManip($data)
{
// match all image tags (thanks to Jan Reiter)
@preg_match_all(/\ *[img][^\]*[.]*\/i, $data, $matches);
if( is_array($matches[0]) )
{
// put all those image tags in one string, since preg match all
needs the data
// to be in a string format
foreach($matches[0] as $match)
{
$imageMatch .= $match;
}
// match all source links within the original preg match all output
@preg_match_all(/src=\(.+?)\/i, $imageMatch, $m);
// for each match that has the same key as the second match,
replace the entire
// tag with my img tag that includes width, height and border=0
foreach($matches[0] as $imageTagKey = $imageTag)
{
foreach($m[1] as $imageSrcKey = $imageSrc)
{
if($imageTagKey == $imageSrcKey)
{
$imageStats = imageProportions($imageSrc);
$data = str_replace($imageTag, img src=\.$imageSrc.\
width=\.$imageStats[0].\ height=\.$imageStats[1].\
border=\0\ /, $data);
}
}
}
}
return $data;
}
2007/8/10, Jan Reiter [EMAIL PROTECTED]:
Maybe this is what you are searching for:
$images = array();
$data = blah img src=img.png width=\400\ height='600' src=blah.png img
src=gg.tiff;
preg_match_all(/\ *[img][^\]*[.]*\/i, $data, $matches);
foreach($matches[0] as $match)
{
preg_match_all(/(src|height|width)*= *[\\']{0,1}([^\\'\ \]*)/i,
$match, $m);
$images[] = array_combine($m[1],$m[2]);
}
print_r($image);
It will produce:
Array
(
[0] = Array
(
[src] = img.png
[width] = 400
[height] = 600
)
[1] = Array
(
[src] = gg.tiff
)
)
I wrote it just as an example. So you may modify it for your needs!
Does anyone know if there is a way to put this into ONE regex??

How can i match an image tag correctly so it does not cause any issues

style
#your_content_div img { max-width: 500px !important; }

OK, so it won't work with IE6. Screw them.
But if the height is set in the img tag it'll keep that, so the image
could become distorted. So, you could also do something like:
#your_content_div img { visibility: none; }
Then run some Javascript routine onload to properly figure the
dimensions of each image. Adjust the width down to 500px, if necessary,
then the height by whatever percent difference between original width
over new width:
var new_height = (original_width / 500) * original_height;
Then, whether you change the dimensions of the image

properties, and if the width is more than 500, i shrink it down and
add width=X and height=Y properties to the image tag.
How can i match an image tag correctly so it does not cause any issues
with how the user adds the image.

Re: [PHP] MD5 bot Question
You were talking about an OCR reader for the arrows to see what letters it is pointing to. If the arrow would be at a random location in the actual image, the arrow being not an arrow but ie. a man pointing and the arm being flexible (so even if the man himself would move around randomly, the arm would always face the right direction for the image. I like the idea of a pointing arrow, it could be quick, pretty effective (not 100% since nothing is) and easy for the user to identify. If there was a miniature version of this available, i would use it on my site. Since i hate the text versions. - Olafur W 2007/4/10, tedd [EMAIL PROTECTED]: At 8:10 PM -0400 4/9/07, Robert Cummings wrote: On Mon, 2007-04-09 at 17:14 -0400, tedd wrote: At 4:39 PM -0400 4/9/07, Robert Cummings wrote: On Mon, 2007-04-09 at 22:27 +0200, Tijnema ! wrote: This is exactly what tedd did in his last arrow example.

You would still leave at least one pixel the same as it was before so your chicken ass would still be exposed, right? Or does your ripple/watermark application alter every pixel by changing its alpha channel or something? And if so, then why is it that you are required to change every pixel? I am sure that there are images that have at least one pixel in common, so I don't see the point you're trying to make -- please explain.

[PHP] Session Authentication
Lets say i have a login system. This system authenticates the user via mysql, when the user is authenticated, i set a session variable to let the system know the user is authenticated. ie. $_SESSION[authenticated] = true; Lets also say i know that's how the system works, that a session variable within my browser is set to true. Could i do this if i knew all this info and authenticate myself by setting the variable from the client side? If it is possible, what can i do to prevent this or increase security?

No. You're teminology indicates a major lack of understanding regarding how sessions work. Session variables are not within [your] browser. The only thing stored in the browser (usually as a cookie) is the session ID. The contents of the session are stored on the server. So, given that, the answer to your question is... not unless your code is exploitable to allow the user to arbitratily set session variables. -Stut
Re: [PHP] Session Authentication
Thanks for the replies guys, became a pretty big thread. The actual code is just a select statement from the user table using sprintf and mysql_real_escape_string for the username and password. I count how many row's the select statement returns, if its not zero then i authenticate by setting a session variable to true (the one in my 1st post) Thanks again. 2007/4/9, Martin Marques martin@bugs.unl.edu.ar: Stut escribió: As with most things these days it probably breaches the DMCA.

Hi everyone,
Is there any function that return the name of the variable??
i.e.
$foo='abc';
$bar=somefunc($foo); // $bar='foo' here
Thanks

Re: [PHP] causing HTTP error status

That's right. Apache's not going to take action based mod_perl and mod_python can both do this. As can CGIs. So I'll be really surprised if this isn't possible with PHP. It's strange because the docs say this can be done; I can't find an example that is purported to work outside of the docs though. Where do the docs say this? I can't find it in http://php.net/header. The url is: http://www.php.net/manual/en/function.header.php The relevant bit is where it says: There are two special-case header calls. The first is a header that starts with the string HTTP/ (case is not significant), which will be used to figure out the HTTP status code to send. For example, if you have configured Apache to use a PHP script to handle requests for missing files (using the ErrorDocument directive), you may want to make sure that your script generates the proper status code. ?php header(HTTP/1.0 404 Not Found); ? I gotta go with Nic on this... Either I'm being really obtuse, or it just plain don't work right. Consider this minimalist example: http://l-i-e.com/404/test.php http://l-i-e.com/404/index.htm The 404 header is being completely ignored, afaict I tried adding exit; right after the header, and my browser just goes way long time and then times out. I tried HTTP/1.1 and that made no difference. I'd suggest checking http://bugs.php.net and filing a bug report if it's not a known issue... Unless somebody can point out something wrong in our logic. I think this got cleared up. Setting the response code (to 404 or 500) is available so that when a PHP _is_ an error page it can set the code correctly; eg: apache config: Directory /someplace ErrorDocument 404 /somplace/error.php /Directory /someplace/error.php ?php header(HTTP/1.1 404 Not Found); echo htmlbodyh1Sorry, the page you wanted wasn't found./h1/body/html; ? But I'm still schocked that PHP can't cause the Apache error page to be served. It seems such a basic thing and all the other web environments I know (even apache + servlets) allow this. Ah well. Nic Wild Guess here but isnt it because apache defines within its config the error pages before it defines .php as a usable proccess? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

More time to go do what you like to do better. Direct memory access beats secondary helper memory every time. Autocomplete is an incentive to have a lazy mind.

Additionally, when you are typing out a flow of code, anything that interrupts that flow slows you down... ala autocomplete. --- Let's agree to disagree. When you have the experience, autocomplete does save you a lot of time. I realized I was working a lot faster with autocomplete on.

Re: [PHP] Sanity checker?
How would you define ie. a sane case or elseif statment without knowing more about the code, how it is executed or included files that effect the file. File that the checker possibly doesnt have access to. Björn Bartels wrote: Hi, there... agreeing with other posts, i'd say this could easily be done by quality management. don't know if there are any recommended international standards [ www.iso.org ] , but i think this would be a good start. worst case, you will have to define those rules all by yourself. as far as i know there are some university projects trying to build some piece of software to do that... bb Well, Since my original post failed to generate reasonable feedback, not even a successful kick at people's funny bone or a flame, let me restate my question with a story. Php reduces the barrier to web development quite a bit, such that less technical people can jump in really easily. In one side, this is great because it helps the adoption of the language, and more people get to create their dynamic websites. The flip to it is that many non-technical people write low quality php code, which in turn make their code vulnerable and not scalable. I envision a tool that would audit your php code, and tell you if your code is good or not, if it has scaling issues, etc, etc. Basically it tells if your php code is sane or not. I have a few ideas of how a sane php code should look like, but I certainly don't know everything. That's the reasons behind my earlier questions. Basically I am looking for things to check in codes that pose high running time risks. Or even simpler, I am looking for best practices, advices, guidelines that you would give to new php developers. So here are the questions again: Does anyone know of any tools to test the sanity of your php code? If you were to check the sanity of your code, what would you look for? Any pointers for other resources?

(But not in large numbers) http://www.camelotherald.com/xml/spells-si.xml It is a spell listing for an online mmorpg. It has a spell_list that captures all other tags and a spell_line for each spell line. Within each spell line is a spell which has the detailed info for each spell with in the spell_line I could parse this by echoing the fixed variables but due to its size and the changes done over time its just to much work. This is why i come to a stop. Ive read some guides and tried some example code that should help me through this. What i hoped to get is an example with the xml i provided so i could work with it to complete the project. The example could look something like this: Header with the selected spell_line name ie. Calefaction and below that the spell info in some dummy table format. Then the next spell_line which is Path of Earth then with the spell info in some dummy table setup. Thanks for reading and i hope someone can show me the light of a real xml parse. The comments on the Manual page [http://www.php.net/manual/en/ref.xml.php] contain an example class that parses an XML file into an associative array. I'm using something similar myself, as it seems to be a pretty straightforward way to get an easy-to-use structure in PHP 4 without dom_xml, which isn't always available. Mattias I have been trying as i said above with the php.net examples, the sitepoint examples (which have been great to give me some view of what i need and how it functions basicly) but with no luck. I can make it easy with fixed value but the dynamic part of it is still outside my reach for now.
