javascript is client-side. php is server-side. The php code runs once, when the page is loaded.

To trigger server-side code to happen when you click, that click must trigger a page to load. (or a form to be posted, etc.)

You can use the javascript to make a hidden form post, or cause a page retrieval to silently happen via an xmlhttprequest object, etc, etc.

Make it a link to the same page, so that people can click it. No javascript need be involved at all. Of course, on click, the page will be reloaded.
