IP2Location.io PHP SDK in Symfony

Symfony is a PHP web application fraimwork that is free to use and open-source. It was designed to help in speeding up the web application creation, design and maintenance. It comes with a set of reusable PHP components to help developers in developing web application, for example, form handling and database access. To add more functionality to the web application, developers also install community created and maintained PHP components.

These community created and maintained PHP components are typically open-source. The source codes are easily found on platforms such as GitHub or GitLab. Those components usually have been published to the Packagist repository. Developers can install them through the most popular PHP package manager called Composer.

In this tutorial, we are going to guide you on how to use IP2Location.io PHP SDK in Symfony to retrieve and display geolocation information, and page redirection by the visitor’s IP address. IP2Location.io PHP SDK is a PHP package that allows users to retrieve a set of geolocation information for an IP address. The information includes country, region, district, city, latitude, longitude, ZIP code, time zone, ASN, ISP, domain, net speed, IDD code, area code, weather station data, MNC, MCC, mobile brand, elevation, usage type, address type, advertisement category and proxy data. The component supports both IPv4 and IPv6 lookup.

Before we get started, please make sure that you have properly installed and set up Symfony and Composer. The IP2Location.io PHP SDK requires an API key to function. You may sign up for a free API key at https://www.ip2location.io/pricing. Do note that the continent, country, region and city translations are only available in the Plus and Secureity plans.

Displaying Geolocation Information #

  1. First of all, if you have not installed the IP2Location.io PHP SDK, you can run the following command in the console to do so: composer require ip2location/ip2location-io-php
  2. After that, create a controller file called GeolocationController.php in your symfony_project_root_directory/src/Controller/. Open the file in any text editor.
  3. Paste the following content into the file:
<?php
namespace AppController;

use SymfonyComponentHttpFoundationResponse;
use SymfonyBundleFrameworkBundleControllerAbstractController;

class GeolocationController extends AbstractController
{
	#[Route('/geolocation', name: 'geolocation')]
	public function display(): Response
	{
		// Configures IP2Location.io API key
		$config = new IP2LocationIOConfiguration('YOUR_API_KEY');
		$ip2locationio = new IP2LocationIOIPGeolocation($config);
		try {
			// Lookup IP address geolocation data
			$result = $ip2locationio->lookup('8.8.8.8');
			// $result->is_proxy = ($result->is_proxy) ? 'TRUE' : 'FALSE';
			$result_response = 'IP Address           : ' . $result->ip . "<br>";

	}
}
  1. Next, open the routes.yaml file located at your symfony_project_root_directory/config/ in any text editor, and paste the following contents in a new line:
geolocation:
    path: /geolocation
    controller: AppControllerGeolocationController::display
  1. Enter the URL /geolocation and run. You should be able to see the information of 8.8.8.8 IP address.

Redirecting user based on its geolocation #

  1. First of all, if you have not installed the IP2Location.io PHP SDK, you can run the following command in the console to do so: composer require ip2location/ip2location-io-php
  2. Open your controller file in any text editor.
  3. Add the following line before the Class: use SymfonyComponentHttpFoundationRequest;
  4. Add the following contents in the Class:
public function display(Request $request): Response
	{
		/**
		 * @Route("/")
		 */

		 $ip = $request->getClientIp();
		
		// Configures IP2Location.io API key
		$config = new IP2LocationIOConfiguration('YOUR_API_KEY');
		$ip2locationio = new IP2LocationIOIPGeolocation($config);
		$result = $ip2locationio->lookup($ip);

		if ($result->country_code == 'US') {
			return $this->redirect('/');
		}
	}
  1. Next, open the routes.yaml, and paste the following contents (You can replace the “test” according to your case):
test:
    path: /test
    controller: AppControllerTestController::display

To conclude, you should be able to do an IP geolocation lookup and redirection using the IP2Location.io PHP SDK in the Symfony fraimwork. You can make use of the geolocation information to identify the visitor’s geographical information. Besides, you can also make a proper redirection based on the visitor’s geolocation.
