What potential issues can arise when attempting to delete a cookie in PHP, and how can they be resolved?

When attempting to delete a cookie in PHP, potential issues can arise if the cookie parameters do not match when setting and deleting the cookie. To resolve this, ensure that the cookie name, path, domain, and secure parameters are the same when deleting the cookie as when it was initially set. 

// Set the cookie
setcookie("example_cookie", "", time() - 3600, "/");

// Delete the cookie by setting an expired time in the past
