What are the advantages and disadvantages of using output buffering in PHP to display forum content within a CMS, particularly in terms of editability and link redirection?

When displaying forum content within a CMS using PHP, output buffering can be advantageous as it allows for easier manipulation and customization of the displayed content. However, it may also introduce complexities in terms of editability and link redirection, as the buffered content may need to be modified before being displayed.

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

// Display forum content here

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

// Manipulate and customize the content as needed
// For example, you can use regular expressions to modify links or add custom styles

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