Parse JSON array

Question

I am using the google geocode api and it creates an array that I am not sure how to use. I need to pull specific elements from this array. Particularly the last latitude and longitude that is in the array.

{
    "results": [
        {
            "address_components": [
                {
                    "long_name": "1600",
                    "short_name": "1600",
                    "types": [
                        "street_number"
                    ]
                },
                {
                    "long_name": "President's Park",
                    "short_name": "President's Park",
                    "types": [
                        "establishment"
                    ]
                },
                {
                    "long_name": "Pennsylvania Avenue Northwest",
                    "short_name": "Pennsylvania Ave NW",
                    "types": [

                },
                {

Array
(
    [latitude] => -77.0365123
    [longitude] => 38.8978378
    [location_type] => ROOFTOP

Edit

Since you have results in JSON and the structure is clear now with more formatting, here is how you can get to lat or lng value in that result

$object=json_decode($json);
$lat=$object->results[0]->geometry->location->lat; // same style for lng
echo $lat;
