"results" : [
{
"address_components" : [
{
"long_name" : "Los Angeles",
"short_name" : "Los Angeles",
"types" : [ "locality", "political" ]
},
{
"long_name" : "Los Angeles County",
"short_name" : "Los Angeles County",
"types" : [ "administrative_area_level_2", "political" ]
},
{
"long_name" : "California",
"short_name" : "CA",
"types" : [ "administrative_area_level_1", "political" ]
},
{
"long_name" : "United States",
"short_name" : "US",

],
"formatted_address" : "Los Angeles, CA, USA",
"geometry" : {
"bounds" : {
"northeast" : {
"lat" : 34.3373061,
"lng" : -118.1552891
},
"southwest" : {
"lat" : 33.7036519,
"lng" : -118.6681759
}
},
"location" : {
"lat" : 34.0522342,

"location_type" : "APPROXIMATE",
"viewport" : {

"lng" : -118.1552891
},
"southwest" : {

}
],
"status" : "OK"
}
I want to get location ==> lat = 34.0522342 and location ==> lng = -118.2436849 from json format.
Then i use this code.
<?php
$url = 'https://maps.googleapis.com/maps/api/geocode/json?address=usa,califonia,Los%20Angeles&key={API-KEY}&language=EN';
$json = file_get_contents($url);
$json_data = json_decode($json, true);
$location_lat = $json_data['results']['location']['lat'];
$location_lng = $json_data['results']['location']['lng'];
echo $location_lat;
echo $location_lng;
?>
But i not get any data ? How can i do ?

Answer 1

If you get the layers of data correct, then you should use...
$location_lat = $json_data['results'][0]['geometry']['location']['lat'];
$location_lng = $json_data['results'][0]['geometry']['location']['lng'];
echo $location_lat.PHP_EOL;
echo $location_lng;
Which outputs...
34.0522342
-118.2436849

Answer 2

you can edit to
$location_lat = $json_data['results'][0]['geometry']['location']['lat'];
$location_lng = $json_data['results'][0]['geometry']['location']['lng'];
