What are common syntax errors that beginners may encounter when trying to combine login scripts with sessions in PHP?

One common syntax error that beginners may encounter when combining login scripts with sessions in PHP is forgetting to start the session before setting or accessing session variables. To solve this issue, make sure to call session_start() at the beginning of your script to initialize the session before using any session-related functions. 

<?php
session_start();

// Check if the user is logged in and set session variables
if($loggedIn) {
    $_SESSION['user_id'] = $user_id;
    $_SESSION['username'] = $username;
}
?>
