In what ways can PHP be integrated with Facebook's API to track likes and shares for verification purposes?

To track likes and shares for verification purposes using Facebook's API, you can integrate PHP with the Graph API provided by Facebook. This allows you to make requests to Facebook's API to retrieve data on likes and shares for specific posts or pages. By using PHP to send requests to the Graph API and parse the JSON response, you can track and verify the engagement metrics of your content on Facebook.

<?php

$access_token = 'YOUR_FACEBOOK_ACCESS_TOKEN';
$post_id = 'POST_ID_TO_TRACK';

$url = 'https://graph.facebook.com/v11.0/' . $post_id . '?fields=engagement&access_token=' . $access_token;

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$response = curl_exec($ch);

curl_close($ch);

$data = json_decode($response, true);

$likes = $data['engagement']['reaction_count'];
$shares = $data['engagement']['share_count'];

echo 'Likes: ' . $likes . '<br>';
echo 'Shares: ' . $shares;

?>
