How to get latitude and longitude from google API?

1) Using Curl 

$address = urlencode('858 King Georges Road, South Hurstville, New South Wales, Australia');

 

 $details_url = "http://maps.googleapis.com/maps/api/geocode/json?address=" . $address . "&sensor=false";

   $ch = curl_init();

   curl_setopt($ch, CURLOPT_URL, $details_url);

   curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

   $geoloc = json_decode(curl_exec($ch), true);

    echo   $latitude              = $geoloc['results'][0]['geometry']['location']['lat'];

    echo  $longitude             = $geoloc['results'][0]['geometry']['location']['lng'];

2) Using file_get_contents

$address = urlencode('858 King Georges Road, South Hurstville, New South Wales, Australia');

$coordinates = json_decode($coordinates,true);

echo $latitude              = $coordinates['results'][0]['geometry']['location']['lat']; 

echo $longitude             = $coordinates['results'][0]['geometry']['location']['lng'];
