ID: 41107 Updated by: scottmac@php.net Reported By: brianm at dealnews dot com -Status: Open +Status: Bogus Bug Type: PCRE related Operating System: Mac and Linux PHP Version: 5.2.1 New Comment: Sorry, but your problem does not imply a bug in PHP itself. For a list of more appropriate places to ask for help using PHP, please visit http://www.php.net/support.php as this bug system is not the appropriate forum for asking support questions. Due to the volume of reports we can not explain in detail here why your report is not a bug. The support channels will be able to provide an explanation for you. Thank you for your interest in PHP. pcre.backtrack_limit was added in PHP 5.2.0 this corresponds to PCRE_EXTRA_MATCH_LIMIT or PCRE which limits the number of matches and by default its 10,000.

He tested up to over 400k of data with PCRE and had no problems. So, I am thinking this is a PHP issue. Basically, (.+?) will not match over 99,997 bytes. This worked in PHP 5.0 and all previous versions I have used. Reproduce code: --------------- <?php $string = "<tag>".str_repeat("x", 99997)."</tag>"; if(preg_match('/<tag>(.+?)<\/tag>/', $string, $match)){ echo "Match 99997!\n"; } $string = "<tag>".str_repeat("x", 99998)."</tag>"; if(preg_match('/<tag>(.+?)<\/tag>/', $string, $match)){ echo "Match 99998!\n"; } ?> Expected result: ---------------- Match 99997! Match 99998! Actual result: -------------- Match 99997! ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=41107&edit=1
