What are some potential pitfalls when using session variables for debugging purposes in PHP?

One potential pitfall when using session variables for debugging purposes in PHP is that they can persist between different requests, leading to outdated or incorrect data being displayed. To solve this issue, make sure to unset or clear the session variables once they have been used for debugging. 

// Clear session variables after debugging
session_start();

// Debugging code here

// Clear session variables
$_SESSION = array();
session_destroy();
