What is the role of an Umleitungsdatei in PHP redirection and how is it implemented?

An Umleitungsdatei in PHP redirection is a file that helps redirect users to a different URL or page. It is commonly used when a website needs to redirect users from one page to another, such as during maintenance or when a page has moved. To implement an Umleitungsdatei in PHP redirection, you can create a PHP file with header() function to send a Location header with the new URL.

<?php
// Umleitungsdatei.php

// Redirect to a new page
header("Location: https://www.newpage.com");
exit;
?>
