How can PHP developers ensure secure session handling in their applications?

To ensure secure session handling in PHP applications, developers should use session_regenerate_id() to regenerate session IDs periodically, use HTTPS to encrypt data transmission, and store session data securely on the server side. 

// Start secure session
session_start();

// Regenerate session ID periodically
if (mt_rand(1, 100) == 1) {
    session_regenerate_id();
}

// Set session data
$_SESSION['user_id'] = 123;

// Use HTTPS to encrypt data transmission
if ($_SERVER['HTTPS'] !== 'on') {
    header('Location: https://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI']);
    exit();
}
