How can the output buffering feature in PHP be utilized to capture and save echo outputs?

To capture and save echo outputs in PHP, you can utilize the output buffering feature. This feature allows you to store all the outputs that would normally be sent directly to the browser in a buffer instead. You can then retrieve and save this buffered content as needed. 

<?php
ob_start(); // Start output buffering

echo "This will be captured and saved.";

$output = ob_get_clean(); // Get the buffered content and save it to a variable

file_put_contents('output.txt', $output); // Save the captured output to a file

echo "Output saved to output.txt!";
?>
