note 77372 added to function.array-key-exists

hey - I thought this function maybe useful to someone somewhere.. It works on an array of the keys you want to check exist. you could pass in the names of form fields and the POST array - suppose it could be useful in aiding form validation. function array_keys_exist(array $keys, array $toCheck, $whichKey = false) { foreach ($keys as $array_key) { if (! array_key_exists($array_key, $toCheck)) { // return first key thats not found. if ($whichKey) { return $array_key; } else { return false; } } } // all keys exist return true; } hope someone finds it useful :) ---- Server IP: 203.220.0.234 Probable Submitter: 123.100.64.24 ---- Manual Page -- http://www.php.net/manual/en/function.array-key-exists.php Edit -- https://master.php.net/note/edit/77372 Del: integrated -- https://master.php.net/note/delete/77372/integrated Del: useless -- https://master.php.net/note/delete/77372/useless Del: bad code -- https://master.php.net/note/delete/77372/bad+code Del: spam -- https://master.php.net/note/delete/77372/spam Del: non-english -- https://master.php.net/note/delete/77372/non-english Del: in docs -- https://master.php.net/note/delete/77372/in+docs Del: other reasons-- https://master.php.net/note/delete/77372 Reject -- https://master.php.net/note/reject/77372 Search -- https://master.php.net/manage/user-notes.php
