What are common methods for managing session cleanup in PHP applications to prevent database clutter?

Session cleanup in PHP applications can be managed by setting up a cron job or scheduled task to regularly clean up expired sessions from the database. This helps prevent database clutter and improves overall performance of the application. 

// Clean up expired sessions from the database
// This code can be run as a cron job or scheduled task

// Connect to the database
$pdo = new PDO('mysql:host=localhost;dbname=your_database', 'username', 'password');

// Delete sessions that have expired
$stmt = $pdo->prepare("DELETE FROM sessions WHERE expiry < :current_time");
$stmt->bindValue(':current_time', time(), PDO::PARAM_INT);
$stmt->execute();
