How

To delete a cookie, call setcookie() with the cookie name and any value such as an empty string), and pass in an expires argument that is in the past.

Example

You should pass exactly the same path, domain, and other fields that you used when you first created the cookie to ensure that the correct cookie is deleted:

This example sets the fontSize cookie's expiry time to one hour in the past, which effectively deletes it from the browser.

Note

As with creating and updating cookies, deleting a cookie via setcookie() doesn ' t delete it from the $_COOKIE array while the script is running.

However, the next time the browser visits the page, it will no longer send the cookie to the server and the corresponding $_COOKIE array element will not be created.
