From: virteman at hotmail dot com Operating system: windows and linux PHP version: 5.2.2 PHP Bug Type: *Regular Expressions Bug description: preg_match_all cannot matches long string Description: ------------ This code read a file(bcgm.txt) and use regex to process the content,then write a new file(yes.txt)! I try it on PHP5.1.6,the result is just fine,but If I run it on PHP2.X the result file is bad and just a NULL in the file. And Then ,I try other method ,Let the content short ,it's also OK,but let the content keep very long,the problem is still. preg_match_all() cannot matches very long string.
