#19690 [Ver]: mb_split is broken

ID: 19690 Updated by: moriyoshi@php.net Reported By: jc@mega-bucks.co.jp Status: Verified Bug Type: mbstring related Operating System: Red Hat Linux 7.2 PHP Version: 4.2.3 New Comment: As of current implementation, mb_split() and mb_ereg() take the regex pattern as extended mode one, in which white spaces, carridge returns, and line feeds are ignored and any sequences beginning with "#" and delimitted by "\n" are treated as comments. So if you would like to use these characters in the pattern, you should escape them with a backslash '\'. IMO this implied behaviour is quite confusing, as we are more familiar with split() and preg_split().
