What is the common issue related to session_start in PHP scripts?

The common issue related to session_start in PHP scripts is that it must be called before any output is sent to the browser. This means that there should be no whitespace or HTML tags before the session_start() function is called. To solve this issue, make sure that session_start() is the first thing in your PHP script, before any other code or output. 

<?php
// Ensure session_start is called before any output
session_start();

// Rest of your PHP code goes here
?>
