How can PHP header functions be used to redirect users to specific pages within a website?

To redirect users to specific pages within a website using PHP header functions, you can use the header() function with the Location parameter set to the URL of the page you want to redirect to. This will send a raw HTTP header to the browser, instructing it to redirect to the specified page.

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