You can not call a PHP (server-side language) function when clicking on a link. From your question, I suspect you want to provide a link for users to logout, below is how you should go about.

Your link should be like:

<a href="logout.php">Click here to log out</a>

And in logout.php you should put php code for logging the user out.

Code inside logout.php might look like this:

<?php
  session_start();
  unset($_SESSION['user']); // remove individual session var
  session_destroy();
  header('location: login.php'); // redirct to certain page now
?>
