How can the use of ob_start() help resolve PHP session-related issues?

When dealing with PHP session-related issues such as headers already sent errors, using ob_start() can help by buffering the output before sending it to the browser. This allows you to set session variables or headers without encountering errors due to premature output. 

<?php
ob_start();
session_start();

// Your PHP code here

ob_end_flush();
?>
