What are common pitfalls to avoid when working with sessions in PHP, such as creating and managing session variables for different user actions?

One common pitfall when working with sessions in PHP is not properly initializing the session at the beginning of each script that needs to access session variables. To avoid this issue, always start the session at the beginning of your PHP scripts using session_start(). Additionally, make sure to properly set, get, and unset session variables as needed to manage user actions. 

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

// Set a session variable
$_SESSION['user_id'] = 123;

// Get a session variable
$user_id = $_SESSION['user_id'];

// Unset a session variable
unset($_SESSION['user_id']);
?>
