How can developers ensure that session data is properly destroyed after the time limit is reached in PHP?

Session data in PHP can be properly destroyed after the time limit is reached by setting the session expiration time using the `session.gc_maxlifetime` directive in the php.ini file. Additionally, developers can manually destroy the session data by calling `session_destroy()` function when the time limit is reached. 

// Set session expiration time
ini_set('session.gc_maxlifetime', 3600); // 1 hour

// Start the session
session_start();

// Check if session expiration time is reached
if (isset($_SESSION['LAST_ACTIVITY']) && (time() - $_SESSION['LAST_ACTIVITY'] > 3600)) {
    // Destroy session data
    session_unset();
    session_destroy();
}

// Update last activity time
$_SESSION['LAST_ACTIVITY'] = time();
