note 98953 added to function.array-diff

A small improvement on "thefrox at gmail dot com" function This one preserves the key function multidimensional_array_diff($a1,$a2) { $r = array(); foreach ($a2 as $key => $second) { foreach ($a1 as $key => $first) { if (isset($a2[$key])) { foreach ($first as $first_key => $first_value) { foreach ($second as $second_value) { if ($first_value == $second_value) { $true = true; break; } } if (!isset($true)) { $r[$key][$first_key] = $first_value; } unset($true); } } else { $r[$key] = $first; } } } return $r; } ---- Server IP: 69.147.83.197 Probable Submitter: 188.220.43.134 ---- Manual Page -- http://www.php.net/manual/en/function.array-diff.php Edit -- https://master.php.net/note/edit/98953 Del: integrated -- https://master.php.net/note/delete/98953/integrated Del: useless -- https://master.php.net/note/delete/98953/useless Del: bad code -- https://master.php.net/note/delete/98953/bad+code Del: spam -- https://master.php.net/note/delete/98953/spam Del: non-english -- https://master.php.net/note/delete/98953/non-english Del: in docs -- https://master.php.net/note/delete/98953/in+docs Del: other reasons-- https://master.php.net/note/delete/98953 Reject -- https://master.php.net/note/reject/98953 Search -- https://master.php.net/manage/user-notes.php
