How can the CORS header 'Access-Control-Allow-Origin' be added to resolve the issue?

The CORS header 'Access-Control-Allow-Origin' can be added to resolve the issue by setting it to the appropriate value in the server's response headers. This header specifies which origins are allowed to access the resources of the server, thereby preventing the CORS policy from blocking the request. 

<?php
header("Access-Control-Allow-Origin: *");
// Other headers that may be needed
// header("Access-Control-Allow-Methods: GET, POST, OPTIONS");
// header("Access-Control-Allow-Headers: Content-Type");
// Rest of your PHP code
?>
