How to upload a webpage to a local network(connected using WiFi or ehernet cable) so that users connected to that network can access it?

I have created a login page(html form page) that asks for username and password and then sends it to ABC.php and if correct, it redirects them to another site.I have installed xampp server for it. But now I want that this feature should extend to my friends connected to my pc by some WiFi or Ethernet cable i.e. they should able to access login page...enter there creditials and access the other site..
