Question

In case somebody knows, how can I make a hyperlink in PHP…

<?php
  echo( '<a href="index.php">Log-out</a>' );
?> 

that would not only to navigate to the first page, but also remove cookies?

Thanks!

Answer 1

Submit a parameter in your link like index.php?logout=true, check for that parameter in your index.php and if set, delete cookies:

http://php.net/manual/de/function.setcookie.php

If you set the “lifetime” (expire) of a cookie to something in the past (or leave it out completely), it will be removed on the next pageload (do a Google search for “php delete cookie” to find help). Force a page reload, if needed.

You may also want to destroy the user’s session.
