Note Submitter: dj dot bettega at gmail dot com ---- 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; }
