How can a PHP developer ensure that a link redirects to the correct page, such as YouTube, on a website?

To ensure that a link redirects to the correct page, such as YouTube, on a website, a PHP developer can use the header() function to send a raw HTTP header to the browser. By setting the "Location" header to the desired URL, the browser will automatically redirect to the specified page. 

<?php
$youtube_url = "https://www.youtube.com";
header("Location: $youtube_url");
exit;
?>
