Google Map API – Geo Location using Address in PHP

In this post, we will discuss Google Map API – Geo Location using Address in PHP. In the given code snippet, we are creating a simple PHP function which receiving only one parameter. And this parameter contains the complete address, that address geolocation generated via the Google Map API.

function getGeoLocation($addr)
{
    $cleanAddress = str_replace (" ", "+", $addr);
    $details_url = "http://maps.googleapis.com/maps/api/geocode/json?address=".$cleanAddress."&sensor=false";
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $details_url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_PROXYPORT, 3128);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
    $geoloc = json_decode(curl_exec($ch), true);
  switch ($geoloc['status']) {
    case 'ZERO_RESULTS':
      return 0;
      break;
    case 'OK':
      return $geoloc['results'][0]['geometry']['location'];
      break;
  }
}

First, we format the address as required by the Google API. Then use the PHP curl function to send a request to the Google API. That function returns an array if location available.

$location = getGeoLocation('7283 N. Lafayette Rd. Dorchester Center, MA 02124');
echo '<pre>';
print_r($location);
echo '</pre>';

// Result
Array
(
    [lat] => 42.8659306
    [lng] => -70.8723014
)
