In what ways can PHP developers prevent security vulnerabilities related to session management in their applications?

One way PHP developers can prevent security vulnerabilities related to session management is by using secure session handling techniques such as using HTTPS, setting secure flags for cookies, and implementing proper session validation and regeneration. 

// Start a secure session
session_set_cookie_params([
    'lifetime' => 0,
    'path' => '/',
    'domain' => 'example.com',
    'secure' => true,
    'httponly' => true,
    'samesite' => 'Strict'
]);
session_start();

// Validate session data
if (isset($_SESSION['user_id'])) {
    // User is authenticated
} else {
    // Redirect to login page
}
