How can one troubleshoot a white page error when attempting to run a PHP script for database backup?

The white page error when running a PHP script for database backup could be caused by a syntax error, a fatal error, or insufficient memory limit. To troubleshoot this issue, check the PHP error logs for any specific error messages, increase the memory limit in the PHP configuration file, and ensure that all necessary PHP extensions are enabled. 

<?php
// Increase memory limit
ini_set('memory_limit', '256M');

// Check for syntax errors
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Enable necessary PHP extensions
extension_loaded('mysqli') or die('MySQLi extension not loaded');

// Your database backup script here
// ...
?>
