Recursive foreach: function array_size($a){ $size = 0; while(list($k, $v) = each($a)){ $size += is_array($v) ? array_size($v) : strlen($v); } return $size; } This could possibly be optimised even more by using references or something like that. eg foreach(array_keys($a) as $k){ size = is_array($a[$k]) =& array_size($a[$k]) : strlen($a[$k]) But I think that for the most part your time programming will be more important than the programs time running.
