Are php files stored on a web server?
<p>I am trying to learn how to use php via ajax and interact with wamp and databases. I do not understand how this works &amp; it's slowing my progress significantly. </p>

<p>When I hear/read "upload php files to your server", what does that mean? I was under the impression that you included all files (php/js/html/etc) in the same folder locally when putting a website/app/etc online - am I mistaken? Are files stored on server and then initiated when called?</p>

<p>Where should php files (specifically scripts to pull and send information) be located? Not understanding this is bottle-necking my progress greatly, so thanks for the help.</p>
