RE: hao2lian There are a lot of alternative - and unfortunately buggy - implementations of strrpos() (or last_index_of as it was called) on this page. This one is a slight modifiaction of the one below, but it should world like a *real* strrpos(), because it returns false if there is no needle in the haystack. <?php function my_strrpos($haystack, $needle) { $index = strpos(strrev($haystack), strrev($needle)); if($index === false) { return false; } $index = strlen($haystack) - strlen($needle) - $index; return $index; } ?> ---- Manual Page -- http://www.php.net/manual/en/function.strrpos.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+55670 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+55670&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+55670&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+55670&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+55670&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+55670&report=yes&reason=non-english Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+55670&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+55670&report=yes Search -- http://master.php.net/manage/user-notes.php
