How To Get Latitude And Longitude From Address Using PHP And Google Maps API?

Hi! In this tutorial, let’s see how to get latitude and longitude from addresses using google maps geocoding API and PHP. Geocoding is the process of converting physical addresses into geographical coordinates such as latitude and longitude so you can use them to create markers on Google Maps. It is also better to provide latitude and longitude when using Google Map API so that you can point to an accurate position on the map. To obtain the geocode, we must send an HTTP request to the Google Map Geocoding API along with the formatted address.

To obtain physical Lat, Lng from the API, you have to send an HTTP request along with address values.

               "lat" : 40.677978,
               "lng" : -73.94438700000001

      },
      
      ...
      ...
   ],
   "status" : "OK"
}

The response sends a status flag which you can test to determine the success or failure of the conversion process.

PHP Function To Get Address From Latitude And Longitude:

Below is the PHP function to get the address details of the given geographic coordinates. You must pass longitude and latitude to the function which makes an HTTP request to the API, receive a JSON response, and parse and return the formatted address.

<?php
function getLatLngFromGoogle($address) {
//Google Map API URL
$API_KEY = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"; // Google Map Free API Key
$url = "http://maps.google.com/maps/api/geocode/json?address=".$address."&key=".$API_KEY."";
Brooklyn,+NY,+USA
// Send CURL Request
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_PROXYPORT, 3128);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
$response = curl_exec($ch);
curl_close($ch);
$returnBody = json_decode($response);
// Google MAP
$status = $returnBody->status;
if($status == "REQUEST_DENIED"){ 
$result = $returnBody->error_message;
} else { 
$data['lat'] = $returnBody->results[0]->geometry->location->lat;
$data['lng'] = $json->results[0]->geometry->location->lng;
} 
return $data; 
} 
?>

Usage:

You have to access the above getLatLngFromGoogle() function like this,

<?php
// coordinates
$address= 'Brooklyn, NY, USA'; 
$result = getAddressFromGoogle($address); 
echo 'Latitude: ' . $result['lat'] . ', Longitude: ' . $result['lng'];
// produces output
// Latitude: 40.6781784, Longitude: -73.9441579
?>
