$this_array_0 = &$array;
$last_key = $keys[$num_last];
for ($i = 0; $i < $num_last; $i++)
{
$this_key = $keys[$i];
$this_var_name = 'this_array_' . $i;
$next_var_name = 'this_array_' . ($i + 1);
if (!array_key_exists($this_key, $$this_var_name)) {
break;
}
$$next_var_name = &${$this_var_name}[$this_key];
}
unset(${$next_var_name}[$last_key]);
