What are best practices for troubleshooting PHP session issues?

When troubleshooting PHP session issues, it's important to check if session_start() is called before any output is sent to the browser. Additionally, ensure that session.save_path is correctly configured in php.ini and that cookies are enabled in the browser. 

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

// Check if session variables are set
if (!isset($_SESSION['user_id'])) {
    $_SESSION['user_id'] = 1;
}

// Use session variables in your code
$user_id = $_SESSION['user_id'];

// Destroy the session
session_destroy();
?>
