Note Submitter: Robbie M (rm at robbie mackay dot com) ---- Slightly improved version of array_diff_assoc_recursive() that handles array indexes which are set to NULL. The only change is to use array_key_exists instead of isset(). function array_diff_assoc_recursive($array1, $array2) { foreach ($array1 as $key => $value) { if (is_array($value)) { if (!array_key_exists($key, $array2)) { $difference[$key] = $value; } elseif (!is_array($array2[$key])) { $difference[$key] = $value; } else { $new_diff = array_diff_assoc_recursive($value, $array2[$key]); if ($new_diff != FALSE) { $difference[$key] = $new_diff; } } } elseif (!array_key_exists($key, $array2) || $array2[$key] != $value) { $difference[$key] = $value; } } return !isset($difference) ? FALSE : $difference; }
