#41588 [Opn]: preg_match offset is in bytes even in unicode mode

ID: 41588 Updated by: tony2001@php.net Reported By: spam02 at pornel dot net Status: Open Bug Type: Documentation problem Operating System: * PHP Version: 6.0.0-dev (20070509) New Comment: >preg_match() with 'u' modifier is supposed to use UTF-8, but this >switch doesn't affect offset parameter, which is always in bytes. Right, PHP is not supposed to parse the regexp to detect which modifiers were used. The byte/codepoint behaviour changes only in Unicode mode.

This gotcha at least deserves to be documented, although consistent unicode support would be even better. Reproduce code: --------------- <?php preg_match('/./u',urldecode('%C2%AE').'NY',$m,NULL,2); echo $m[0]; Expected result: ---------------- Y Actual result: -------------- N ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=41588&edit=1
