How can PHP developers ensure that their applications comply with the Same-Origin Policy to prevent security risks?

To ensure that PHP applications comply with the Same-Origin Policy and prevent security risks, developers can utilize Cross-Origin Resource Sharing (CORS) headers. By setting appropriate headers in PHP responses, developers can control which domains are allowed to access their resources, thereby enforcing the Same-Origin Policy and mitigating potential security vulnerabilities. 

<?php
header("Access-Control-Allow-Origin: https://www.example.com");
header("Access-Control-Allow-Methods: GET, POST, OPTIONS");
header("Access-Control-Allow-Headers: Content-Type");
