What are some best practices for managing and storing cookies in PHP to avoid conflicts or issues like cookie overwriting?

When managing and storing cookies in PHP, it is essential to avoid conflicts or issues like cookie overwriting by ensuring unique cookie names and properly setting the cookie parameters. One common approach is to prefix the cookie names with a unique identifier or namespace to prevent conflicts with other cookies. Additionally, setting the cookie's path and domain correctly can help isolate cookies to specific parts of the website and prevent overwriting.

// Set a unique prefix for the cookie name
$cookieName = 'my_unique_cookie_name';

// Set the cookie with unique name and proper parameters
setcookie($cookieName, $cookieValue, time() + 3600, '/', 'example.com', false, true);
