note 64044 added to function.array-unique

i couldn't see an array function that removed unique values regardless of case so i wrote this crude one. it needs work to optimize it but it works. function array_unique_nocase($array) { foreach($array as $key => $val) { foreach($array as $key2 => $val2) { if($key != $key2 && strtoupper($val) == strtoupper($val2)) { unset($array[$key]); } } } return $array; } used successfully at http://www.iknow-devon.co.uk/all_devon/ on the left after "Accommodation in:" ---- Server IP: 85.116.0.130 Probable Submitter: 82.163.189.70 ---- X-Spam-Status: No, hits=3.1 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/function.array-unique.php Edit -- http://master.php.net/note/edit/64044 Del: integrated -- http://master.php.net/note/delete/64044/integrated Del: useless -- http://master.php.net/note/delete/64044/useless Del: bad code -- http://master.php.net/note/delete/64044/bad+code Del: spam -- http://master.php.net/note/delete/64044/spam Del: non-english -- http://master.php.net/note/delete/64044/non-english Del: in docs -- http://master.php.net/note/delete/64044/in+docs Del: other reasons-- http://master.php.net/note/delete/64044 Reject -- http://master.php.net/note/reject/64044 Search -- http://master.php.net/manage/user-notes.php
