Are there any best practices or guidelines for setting and managing cookies in PHP to avoid issues like constant cookie creation in different browsers?

When setting cookies in PHP, it's important to specify the path and domain parameters to avoid creating multiple cookies in different browsers. By setting these parameters correctly, you can ensure that the cookie is valid for the entire domain and not just a specific page.

// Set cookie with path and domain parameters
setcookie("cookie_name", "cookie_value", time() + 3600, "/", "example.com");
