I am developing a system to get values from gGoogle Api Elevation with PHP. I have it working and when I get the value it returns as String in this format:
{ "results" : [ { "elevation" : 914.033935546875, "location" : { "lat" : -25.4499861, "lng" : -49.2339611 }, "resolution" : 152.7032318115234 } ], "status" : "OK" }
I want to get the value of the elevation in this result, can you help me to do this? thanks you.
The string is in JSON format.
You can use json_decode to convert it to a PHP array.
$json_string = <<<JSON
{
"results": [
{
"elevation": 914.033935546875,
"location": {
"lat": -25.4499861,
"lng": -49.2339611
},
"resolution": 152.7032318115234
}
],
"status": "OK"
}
JSON;
$array = json_decode($json_string, TRUE);
echo $array['results'][0]['elevation'];
Output:
914.03393554688
