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

Hi! Today let’s see how to get addresses from latitude and longitude using PHP and Google Maps Geocoding API. The process of converting geometric coordinates such as latitude and longitude into addresses is called reverse geocoding. And the geocoding is just the opposite, converting an address into latitude and longitude which we have seen in our previous tutorial. Google Maps provides a separate Geocoding API for the purpose and let’s see how to use it with PHP.

To obtain physical addresses from the API, you have to send an HTTP request along with latitude and longitude values.

There are many code snippets available online or on many other blogs and websites, but everyone cannot optimize your blog or website, so you need some optimized code snippets. So now checkout out the code snippet for your blog and website that will give you all features for your desired code. Now grab the ready-to-use code and paste it where you want.

Features:

1. Light Weight.
2. Pure PHP Code.
3. Cross Browser.
4. No External Files.
5. Fully Customizable.

         "types" : [ "street_address" ]
      },
      
      ...
      ...
   ],
   "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 co-ordinates. You must pass longitude and latitude to the function which makes a http request to the api, receive json response, parse and return the formatted address.

<?php
function getAddressFromGoogle($latitude,$longitude) {
//Google Map API URL
$API_KEY = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"; // Google Map Free API Key
$url = "https://maps.google.com/maps/api/geocode/json?latlng=".$latitude.",".$longitude."&key=".$API_KEY."";
// 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 { 
$result = $returnBody->results[0]->formatted_address;
}
return $result;
}
?>

Usage:

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

<?php
// coordinates
$latitude = '40.6781784';
$longitude = '-73.9441579';
$result = getAddressFromGoogle($latitude, $longitude);
echo 'Address: ' . $result;
// produces output
// Address: 58 Brooklyn Ave, Brooklyn, NY 11216, USA
?>
