#48330 [Opn->Bgs]: preg_replace() Pattern Modifiers 'e' Bug

ID: 48330 Updated by: jani@php.net Reported By: seateng at sohu dot com -Status: Open +Status: Bogus Bug Type: PCRE related Operating System: Redhat AS5 PHP Version: 5.2.9 New Comment: RTFM: When using the e modifier, this function escapes some characters (namely ', ", \ and NULL) in the strings that replace the backreferences. This is done to ensure that no syntax errors arise from backreference usage with either single or double quotes (e.g. 'strlen(\'$1\')+strlen("$2")'). Make sure you are aware of PHP's string syntax to know exactly how the interpreted string will look like.
