How to Determine iframe by Regular Expression

Is it the following code that determines whether the url entered is Googlemap iframe?

preg_match("/<iframe src=\"https:\/\/www\.google\.com\/map(.*?)<\/iframe>/s", $map, $is_map);

  if(!isset($is_map[1])){
    echo"Map embedded code is incorrect.";
  } else {
    echo "This is the correct map.";
 }

I have created a system to enter url for the map, so I want to eliminate it when I enter code other than the map.
