Are there best practices for using output buffering in PHP to capture and manipulate HTML content effectively?

When using output buffering in PHP to capture and manipulate HTML content effectively, it is important to follow best practices to ensure proper handling of the output. One common approach is to use ob_start() to start output buffering, ob_get_clean() to capture the buffered output into a variable, and then manipulate the content as needed before displaying it. 

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

// Your HTML content goes here
echo "<h1>Hello, World!</h1>";

// Capture the buffered output into a variable
$html_content = ob_get_clean();

// Manipulate the HTML content as needed
$html_content = str_replace("World", "PHP", $html_content);

// Display the modified HTML content
echo $html_content;
?>
