You need to run a webserver and then request your resource from that using a network name (e.g. http://localhost/cart/welcome.php).

A URL to a local filepath would start with file: instead of http:, but most implementations of XMLHttpRequest would refuse to support it, and it wouldn't cause the PHP to be executed (since PHP, in this context, is a server side programming language).
