note 81484 added to function.array-flip

True, array_unique does preserve keys, but if you are incrementing in a loop, then it will stop once the key values break numerical order. If you don't care about preserving keys, a life-saver (originally a headache) for me was... <?php $new_array = array_keys(array_flip($old_array)); ?> i used this little snip-it after results from preg_match_all() as a way to remove duplicates from an array and then re-organize the numerical keys ;) *Only works on arrays with numerical keys. ---- Server IP: 209.41.74.194 Probable Submitter: 192.251.134.5 ---- Manual Page -- http://www.php.net/manual/en/function.array-flip.php Edit -- https://master.php.net/note/edit/81484 Del: integrated -- https://master.php.net/note/delete/81484/integrated Del: useless -- https://master.php.net/note/delete/81484/useless Del: bad code -- https://master.php.net/note/delete/81484/bad+code Del: spam -- https://master.php.net/note/delete/81484/spam Del: non-english -- https://master.php.net/note/delete/81484/non-english Del: in docs -- https://master.php.net/note/delete/81484/in+docs Del: other reasons-- https://master.php.net/note/delete/81484 Reject -- https://master.php.net/note/reject/81484 Search -- https://master.php.net/manage/user-notes.php
