How can PHP be used to access elements from different domains due to the Origin Policy restrictions?

Due to the Same Origin Policy restrictions, PHP cannot directly access elements from different domains in the client-side script. One way to work around this limitation is to use server-side PHP code to fetch the content from the external domain and then pass it back to the client-side script. This can be achieved by making a request to the external domain using PHP's cURL functions and returning the content to the client. 

<?php
$url = 'https://www.example.com/data.json';
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);

echo $response;
?>
