How can one troubleshoot the lack of PHP output or feedback in a web browser?

To troubleshoot the lack of PHP output or feedback in a web browser, you can check for syntax errors in your PHP code, ensure error reporting is enabled, and verify that the PHP file is being accessed correctly. Additionally, make sure that the PHP interpreter is installed and functioning properly on your server.

<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Your PHP code here

?>
