How can PHP be configured to run a program in the background to prevent the website from waiting for the program's output?

To run a program in the background in PHP, you can use the `exec` function along with appending `&` at the end of the command to run it asynchronously. This will prevent the website from waiting for the program's output and allow the website to continue functioning without delay. 

<?php
$command = 'your_program_command_here &';
exec($command);
?>
