What are some best practices for handling errors related to headers already being sent in PHP scripts?

When headers are already sent in PHP scripts, it typically means that some content has already been output to the browser before headers are set. To solve this issue, make sure to set headers before any content is output, and avoid any whitespace or HTML tags before the opening `<?php` tag. 

&lt;?php
ob_start(); // Start output buffering

// Your PHP code here

ob_end_flush(); // Flush the output buffer
