Get Geocodes Latitude and Longitude using PHP (via Google API)

The below function pulls the Geocode Location Latitude and Longitude values using PHP. It uses the Google API to pull those Geo co-ordinates.

 function getLatLogOfAddress($address='')
 {
  $address = urlencode($address);
  
  //here is the google api url
  $url = "http://maps.googleapis.com/maps/api/geocode/json?address=$address&sensor=false";
  
  //get the content from the api using file_get_contents
  $getmap = file_get_contents($url);
  
  //the result is in json format. To decode it use json_decode
  $googlemap = json_decode($getmap);

  $data = array();
  //get the latitute, longitude, address from google api's json result 
  $googlemap = isset($googlemap->results[0]) ? $googlemap->results[0] : '';
  $data['lat'] = isset($googlemap->geometry->location->lat) ? $googlemap->geometry->location->lat : '';
  $data['lng'] = isset($googlemap->geometry->location->lng) ? $googlemap->geometry->location->lng : ''; 
  $data['address'] = isset($googlemap->formatted_address) ? $googlemap->formatted_address : $address;
  
  return $data;
 }

// Call the function as below;
 $address = "Apollo Victoria Theatre, 17 Wilton Road, Westminster, London, SW1V 1LG, UK";
 $geocodes = $this->getLatLogOfAddress($address);
 print_r($geocodes);
 
// The Result would be...
 Array

     [lat] => 51.4957746
     [lng] => 51.4957746
