How can output buffering be utilized in PHP to manage output effectively?

Output buffering in PHP can be utilized to manage output effectively by capturing the output generated by PHP scripts before sending it to the browser. This allows you to manipulate or modify the output before it is displayed, helping to organize and control the content that is ultimately sent to the user. 

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

// Your PHP code generating output here

$output = ob_get_clean(); // Get the buffered output and store it in a variable

// Manipulate or modify $output as needed

echo $output; // Send the modified output to the browser
?>
