In the provided PHP code, why is it important to include an exit statement after redirecting the user to a login form?

After redirecting the user to a login form, it is important to include an exit statement to prevent the rest of the code from executing. Without the exit statement, the code may continue to execute and potentially reveal sensitive information or allow unauthorized access to certain parts of the application. The exit statement ensures that the redirection is immediate and no further code is processed. 

<?php
session_start();

if(!isset($_SESSION['user'])) {
    header("Location: login.php");
    exit; // Add exit statement to prevent further code execution
}

// Rest of the code here
?>
