Actually I've been using the following function a lot too:
function _array_val($a, $k, $d = null) {
if (array_key_exists($k, $a))
return $a[$k];
if (func_num_args() == 3)
return $d;
throw new Exception("No such array key: $k");
}
--8<-- example --8<--
$val = _array_val($arr, 'key', false);
Of course it's a little slower but it makes for clean code.
