What are common issues related to session cookies in PHP scripts?

Common issues related to session cookies in PHP scripts include not setting the session cookie parameters securely, such as not using the 'Secure' flag for HTTPS connections, not setting the 'HttpOnly' flag to prevent client-side scripts from accessing the cookie, and not setting the 'SameSite' attribute to prevent cross-site request forgery attacks. To solve these issues, you can set the session cookie parameters using the session_set_cookie_params function before starting the session in your PHP script.

// Set session cookie parameters securely
session_set_cookie_params([
    'lifetime' => 0,
    'path' => '/',
    'domain' => 'example.com',
    'secure' => true,  // Set to true for HTTPS connections
    'httponly' => true,  // Prevent client-side scripts from accessing the cookie
    'samesite' => 'Strict'  // Prevent cross-site request forgery attacks
]);

session_start();
