Google Maps API - Retrieving city and state using PHP - php

Question

I'm currently using Google Maps API to get a longitude and latitude form the user's street, street number and zip code.
I would also like to grab their city and state from the Maps API results. The XML document formats it strangely though, and I'm not sure how I'm supposed to reference it (it's different from the way I'm grabbing the long and lat).
This is how I am loading the Maps API:
$map_address = str_replace($address."+".$zip);
$map_api_url = "https://maps.googleapis.com/maps/api/geocode/json?address=".$map_address."&key=myKey";
$resp_json = file_get_contents($map_api_url);
$resp = json_decode($resp_json, true);
I then get the Long and Lat:
$lati = $resp['results'][0]['geometry']['location']['lat'];
$longi = $resp['results'][0]['geometry']['location']['lng'];
But how do I grab the city and state?

Just answered my own question by running the code through a loop. Please let me know if you have a better way!
foreach($resp['results'][0]['address_components'] as $address_componenets) {
if($address_componenets["types"][0]=="country") {
$country = $address_componenets["long_name"];
}
if($address_componenets["types"][0]=="administrative_area_level_1") {
$state = $address_componenets["long_name"];
}
if($address_componenets["types"][0]=="locality") {
$city = $address_componenets["long_name"];
}
}
