note 94492 added to function.array-diff

to Anonymous post, posted on 15-Oct-2009 06:55: quote: "So, as an example: A = 1,2,3 B = 2,3,4 should NOT be: C = 1,4 but: A = 1 B = 4" I think you're wrong. This function "Returns an array containing all the entries from array1 that are not present in any of the other arrays." So you would get C = 1, and NOT C = 1,4. So you could just do it like that: <?php $original = array(1,2,3); $new = array(2,3,4); $delete = array_diff($original, $new); // array(1) $insert = array_diff($new, $original); // array(4) ?> ---- Server IP: 69.147.83.197 Probable Submitter: 78.60.212.119 ---- Manual Page -- http://www.php.net/manual/en/function.array-diff.php Edit -- https://master.php.net/note/edit/94492 Del: integrated -- https://master.php.net/note/delete/94492/integrated Del: useless -- https://master.php.net/note/delete/94492/useless Del: bad code -- https://master.php.net/note/delete/94492/bad+code Del: spam -- https://master.php.net/note/delete/94492/spam Del: non-english -- https://master.php.net/note/delete/94492/non-english Del: in docs -- https://master.php.net/note/delete/94492/in+docs Del: other reasons-- https://master.php.net/note/delete/94492 Reject -- https://master.php.net/note/reject/94492 Search -- https://master.php.net/manage/user-notes.php
