[php] How to use PHP with Visual Studio

Maybe we should help you with a big misunderstanding on your side first: PHP is (like ASP.NET or whatever you used to far) a server side language while javascript is client side.

This means that PHP will run on your webserver and create a HTML page dynamically which is then sent to the browser. Javascript in turn is embedded (either directly or as a referenced file) into this HTML page and runs in the browser.

Maybe you can now understand why your approach so far could never work out.
