  • What function? What exactly are you doing? This is possible, but there may be a better way since JavaScript is client-side and PHP is server-side. – John Kugelman Oct 31 '09 at 06:09

You can't do that - javascript being a client side technology will execute after your PHP script has already finished so there's no way to do what you are looking to accomplish.

    technically you're not calling a javascript function from PHP, you're just using AJAX to get a PHP page - so it's going javascript -> PHP not PHP -> javascript – Marek Karbarz Oct 31 '09 at 07:14
