Is it recommended to use ob_start() and ob_flush() as a workaround for header errors in PHP?

When working with PHP, sometimes header errors can occur if output is sent before headers are set. One workaround for this issue is to use ob_start() and ob_flush() functions to buffer the output and prevent header errors. 

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

// Your PHP code here

ob_flush(); // Flush the output buffer
?>
