note 58560 added to function.in-array

hope this function may be useful to you, it checks an array recursively (if an array has sub-array-levels) and also the keys, if wanted: <?php function rec_in_array($needle, $haystack, $alsokeys=false) { if(!is_array($haystack)) return false; if(in_array($needle, $haystack) || ($alsokeys && in_array($needle, array_keys($haystack)) )) return true; else { foreach($haystack AS $element) { $ret = rec_in_array($needle, $element, $alsokeys); } } return $ret; } ?> ---- Manual Page -- http://www.php.net/manual/en/function.in-array.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+58560 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+58560&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+58560&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+58560&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+58560&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+58560&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+58560&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+58560&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+58560&report=yes Search -- http://master.php.net/manage/user-notes.php
