What are the potential pitfalls when using session variables in PHP scripts for sequential calls?

The potential pitfall when using session variables in PHP scripts for sequential calls is that the session data may not be properly initialized or updated between calls, leading to unexpected behavior or errors. To solve this issue, you can explicitly call session_start() at the beginning of each script to ensure that the session data is properly initialized and updated. 

<?php
// Start the session
session_start();

// Your PHP code here
?>
