What are the best practices for handling output buffering in PHP?

When working with output buffering in PHP, it is important to properly manage and handle the buffer to avoid unexpected behavior or errors. Best practices include starting output buffering at the beginning of the script, flushing the buffer when needed to send the content to the browser, and clearing the buffer at the end of the script to release memory. Additionally, using ob_start() and ob_end_flush() functions can help control the output buffering process effectively. 

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

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

// Flush the buffer to send content to the browser
ob_end_flush();

// Clear the buffer
ob_clean();
?>
