Are there any PHP libraries or frameworks that can simplify the process of implementing a backlink verification system in a web application?

Implementing a backlink verification system in a web application involves checking if external websites are linking back to your site. This can be a time-consuming process, but using PHP libraries or frameworks like Guzzle or Symfony can simplify the task by providing tools for making HTTP requests and parsing HTML content.

<?php
require 'vendor/autoload.php';

use GuzzleHttp\Client;

$client = new Client();
$response = $client->request('GET', 'https://example.com');
$body = $response->getBody();

// Parse HTML content to check for backlinks
// Implement your backlink verification logic here

echo $body;
?>
