How can the issue of headers already sent be resolved in the PHP code snippet related to WordPress themes?

The issue of "headers already sent" in PHP code related to WordPress themes can be resolved by ensuring that there is no whitespace or output before the `header()` function is called. This error occurs when PHP tries to send headers to the browser after output has already been sent. To fix this, make sure that there is no HTML, text, or whitespace before the `<?php` opening tag in your theme's functions.php file. 

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