How can output buffering be used to capture the output of a PHP file in a secure manner?

Output buffering can be used to capture the output of a PHP file in a secure manner by buffering the output before sending it to the browser. This can prevent sensitive information from being leaked or displayed prematurely. To implement this, you can use the ob_start() function to start output buffering at the beginning of the PHP file and then use ob_get_clean() to retrieve the buffered output at the end of the file. 

<?php
ob_start();

// Your PHP code here

$output = ob_get_clean();

// Do something secure with the captured output
