Note that | this changes the return value in an array where every | element is an array consisting of the matched string at | offset 0 and its string offset into subject at offset 1. | This flag is available since PHP 4.3.0 . So it can also return an Array. | preg_match() returns FALSE if an error occurred. And it can return FALSE. So the "int" of the return-value must be changed to "mixed" ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=28408&edit=1
