How can PHP be used to redirect users to a separate window to display a video?

To redirect users to a separate window to display a video using PHP, you can use the header() function to send a Location header with the URL of the video file. This will prompt the browser to open a new window or tab and play the video.

<?php
$videoUrl = "https://www.example.com/video.mp4";
header("Location: $videoUrl");
exit;
?>
