#39005 [Opn->Fbk]: mb_ereg_replace

ID: 39005 Updated by: tony2001@php.net Reported By: php at edwardk dot info -Status: Open +Status: Feedback Bug Type: mbstring related Operating System: Windows 2003 PHP Version: 5.2.1 New Comment: Please try using this CVS snapshot: http://snaps.php.net/php5.2-latest.tar.gz For Windows: http://snaps.php.net/win32/php5.2-win32-latest.zip Cannot reproduce, your code works just fine on Linux both in prefork and threaded mode. Previous Comments: ------------------------------------------------------------------------ [2007-02-21 12:30:53] php at edwardk dot info Further testing shows that ereg_replace throws an error on the particular regex while mb_ereg_replace does not. ------------------------------------------------------------------------ [2007-02-21 12:16:56] php at edwardk dot info I have since upgraded to PHP 5.2.1. I've isolated this bug to a specific function, an example script is shown here: <?php $test = 'afds #blah@irc.freenode.net sfda'; echo $test.'<br>'; $test = mb_ereg_replace('\#([^,]+?)\@(irc(\.[\w\-]+)+)','<a class="irc" href="irc://\2/\1">#\1@\2</a>', $test); echo $test; ?> the intended use for this code segment is to replace irc links in text with clickable ones, eg, "#blah@irc.freenode.net" becomes "<a href="irc://irc.freenode.net/blah">#blah@irc.freenode.net</a> Crashes can be reproduced with ab (ApacheBench) with the following command line: ab -n 1000 -c 50 http://url/ Crashes occur faster when concurrency is higher, at -c 2 or so crashes don't happen. Workaround: Replacing mb_ereg_replace with ereg_replace stops the crashing from occuring, but with loss of multibyte support. ------------------------------------------------------------------------ [2006-10-12 01:00:00] php-bugs at lists dot php dot net No feedback was provided for this bug for over a week, so it is being suspended automatically.

You would have to come up with reproducing script the old fashioned, trial and error way :) ------------------------------------------------------------------------ [2006-10-04 06:52:38] php at edwardk dot info Can a PHP 4.4.4 Win32 debug pack be created? I'm having a very difficult time isolating the script for this problem. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
