Access Values in a JSON Array PHP

Question

I am not having any success getting values out of a JSON array object. I am specifically trying to get to geometry->location->lat

Here is what I am doing:

    $url='http://maps.googleapis.com/maps/api/geocode/json?address='.$a.'&sensor=false';
    $result = file_get_contents($url);
    $jsonArr = json_decode($result,true);

    echo "Lat: ".$jsonArr['results']['geometry']['location']['lat'];

Here is a print_r() of the JSON returned by Google:

 {
       "results" : [
          {
             "address_components" : [
                {
                   "long_name" : "46814",
                   "short_name" : "46814",
                   "types" : [ "postal_code" ]
                },
                {
                   "long_name" : "Fort Wayne",
                   "short_name" : "Fort Wayne",
                   "types" : [ "locality", "political" ]
                },
                {
                   "long_name" : "Indiana",
                   "short_name" : "IN",
                   "types" : [ "administrative_area_level_1", "political" ]
                },
                {
                   "long_name" : "United States",
                   "short_name" : "US",
                   "types" : [ "country", "political" ]
                }
             ],
             "formatted_address" : "Fort Wayne, IN 46814, USA",
             "geometry" : {
                "bounds" : {
                   "northeast" : {
                      "lat" : 41.08472709999999,
                      "lng" : -85.26534090
                   },
                   "southwest" : {
                      "lat" : 41.00163510,
                      "lng" : -85.35540899999999
                   }
                },
                "location" : {
                   "lat" : 41.05472940,
                   "lng" : -85.30328109999999
                },
                "location_type" : "APPROXIMATE",
                "viewport" : {
                   "northeast" : {
                      "lat" : 41.08472709999999,
                      "lng" : -85.26534090
                   },
                   "southwest" : {
                      "lat" : 41.00163510,
                      "lng" : -85.35540899999999
                   }
                }
             },
             "types" : [ "postal_code" ]
          }
       ],
       "status" : "OK"
    }

As a note on the duplicate, you would have to drop the true parameter from the json_decode() — jprofitt

The results are returned in an array. Get the first element and you're done. However you should make sure that you actually have at least one element in the results array.

echo "Lat: " . $jsonArr['results'][0]['geometry']['location']['lat'];
