(http://bugs.php.net/bug.php?id=43788) I guess this was introduced with preg_last_error in PHP 5.2 and should be documented. I guess this applies to other preg_* functions as well. Reproduce code: --------------- Read the online documentation to preg_replace. Expected result: ---------------- Return Values preg_replace() returns an array if the subject parameter is an array, or a string otherwise. If matches are found, the new subject will be returned, otherwise subject will be returned unchanged. If an error occurs, null (or false ?) will be returned and the error will be available through preg_last_error(). Actual result: -------------- Return Values preg_replace() returns an array if the subject parameter is an array, or a string otherwise. If matches are found, the new subject will be returned, otherwise subject will be returned unchanged. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=43789&edit=1
