note 94560 added to function.array-diff

To reply to Anonymous' function: <?php function array_diff_ORG_NEW(&$org, &$new, $type='VALUES'){ switch($type){ case 'VALUES': $int = array_values(array_intersect($org, $new)); //C = A ^ B $org = array_values(array_diff($org, $int)); //A' = A - C $new= array_values(array_diff($new, $int)); //B' = B - C break; case 'KEYS': $int = array_values(array_intersect_key($org, $new)); //C = A ^ B $org = array_values(array_diff_key($org, $int)); //A' = A - C $new= array_values(array_diff_key($new, $int)); //B' = B - C break; } } ?> Why would the following not suffice? (for values) <?php $a = 1,2,3; $b = 2,3,4; //supposing this is the "new" array $a = array_diff($a,$b); $b = array_diff($b,$a); ?> ---- Server IP: 92.48.74.199 Probable Submitter: 82.20.26.189 ---- Manual Page -- http://www.php.net/manual/en/function.array-diff.php Edit -- https://master.php.net/note/edit/94560 Del: integrated -- https://master.php.net/note/delete/94560/integrated Del: useless -- https://master.php.net/note/delete/94560/useless Del: bad code -- https://master.php.net/note/delete/94560/bad+code Del: spam -- https://master.php.net/note/delete/94560/spam Del: non-english -- https://master.php.net/note/delete/94560/non-english Del: in docs -- https://master.php.net/note/delete/94560/in+docs Del: other reasons-- https://master.php.net/note/delete/94560 Reject -- https://master.php.net/note/reject/94560 Search -- https://master.php.net/manage/user-notes.php
