note 88281 added to function.array-key-exists

Here is a little function for case sensitivity to elaborate on what was said by MarkL from ##php (Freenode) and mmanning at mdanderson dot org from this page: // Case sensitive version of array_key_exists() using preg_match() function array_ikey_exists($key,$arr) { if(preg_match("/".$key."/i", join(",", array_keys($arr)))) return true; else return false; } Not that anyone else couldn't have written this, but a concept like this strengthens reusability. :) ---- Server IP: 209.41.74.194 Probable Submitter: 69.205.195.6 ---- Manual Page -- http://www.php.net/manual/en/function.array-key-exists.php Edit -- https://master.php.net/note/edit/88281 Del: integrated -- https://master.php.net/note/delete/88281/integrated Del: useless -- https://master.php.net/note/delete/88281/useless Del: bad code -- https://master.php.net/note/delete/88281/bad+code Del: spam -- https://master.php.net/note/delete/88281/spam Del: non-english -- https://master.php.net/note/delete/88281/non-english Del: in docs -- https://master.php.net/note/delete/88281/in+docs Del: other reasons-- https://master.php.net/note/delete/88281 Reject -- https://master.php.net/note/reject/88281 Search -- https://master.php.net/manage/user-notes.php
