How can PHP developers troubleshoot server errors like "405 Method Not Allowed" when loading content dynamically with jQuery?

To troubleshoot a "405 Method Not Allowed" error when loading content dynamically with jQuery, PHP developers can check the server configuration to ensure that the HTTP method being used (e.g., POST, GET) is allowed for the requested URL. Additionally, they can review the PHP code handling the AJAX request to ensure it is correctly sending the appropriate method type.

<?php
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    // Handle POST request
} elseif ($_SERVER['REQUEST_METHOD'] === 'GET') {
    // Handle GET request
} else {
    http_response_code(405);
    echo 'Method Not Allowed';
}
?>
