I am sorry, but I don't write or attach script, beacose this code from forum phpBB (file includes/bbcode.php). This forum has very much lines of code ;) I am only change property \w on \pL\Sm in 6 functions in this file and apache server memory leak. If I change properties back on \w and restart apache - all work fine. I'm talk with phpBB-developers and they says what this bug in php and recommended usage function mb_eregi_replace() instead of preg_replace() ps: sorry for my bad english :( Previous Comments: ------------------------------------------------------------------------ [2006-09-06 08:38:30] [EMAIL PROTECTED] Thank you for this bug report.
