How can output buffering be used to control what is displayed when including PHP files?

Output buffering can be used to capture the output of included PHP files and manipulate it before displaying it. This can be useful for controlling the order in which content is displayed or applying additional processing to the output. By using functions like ob_start() to start output buffering and ob_get_clean() to retrieve the buffered output, you can modify the content before it is finally displayed. 

<?php
ob_start();
include 'file.php';
$content = ob_get_clean();

// Manipulate $content as needed before displaying it
echo $content;
?>
