How does output buffering affect the session_start() function in PHP?

When output buffering is enabled in PHP, it can cause issues with the session_start() function because headers must be sent before any output is generated. To solve this issue, you can use ob_start() to start output buffering before calling session_start(). 

<?php
ob_start();
session_start();

// Your PHP code here
?>
