note 88290 added to function.array-key-exists

I've been running into issues with escaping for Regex, so I decided to give something like this a shot: <?php function array_ikey_exists($key,$arr) { $e = 0; //$key = addslashes($key); if(is_array($arr) && $arr !==array()) { foreach($arr as $k => $v) { if(strtolower($k) == strtolower($key)) $e++; } if($e>0) return true; else return false; } else return false; } ?> You could addslashes() to escape; it's just another approach. Comments & improvements are welcome. ---- Server IP: 208.69.120.35 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/88290 Del: integrated -- https://master.php.net/note/delete/88290/integrated Del: useless -- https://master.php.net/note/delete/88290/useless Del: bad code -- https://master.php.net/note/delete/88290/bad+code Del: spam -- https://master.php.net/note/delete/88290/spam Del: non-english -- https://master.php.net/note/delete/88290/non-english Del: in docs -- https://master.php.net/note/delete/88290/in+docs Del: other reasons-- https://master.php.net/note/delete/88290 Reject -- https://master.php.net/note/reject/88290 Search -- https://master.php.net/manage/user-notes.php
