How does output buffering in PHP, such as ob_start and ob_end_flush, impact performance compared to concatenating strings for output?

Output buffering in PHP, like using ob_start and ob_end_flush, can impact performance compared to concatenating strings for output because it involves buffering the output before sending it to the browser. This can lead to increased memory usage and slower processing time, especially for large amounts of data. However, output buffering can be useful for managing output content, such as capturing and modifying it before sending it to the client. 

<?php
ob_start();

// Output buffering content
echo "Hello, ";
echo "World!";

ob_end_flush();
?>
