Help with localhost!!!

Okay I must be a complete idiot but I've created a website at school and now that school is ending i transfered it to my friends computer.

I set up all the things I had at school the PHP, Apache Server, and MySQL.

but when I go to the http://localhost site it goes somewhere completely different than my site how do i change the file that is opened by http://localhost

localhost refers to your own computer like 127.0.0.1
if you have set up the web server on your friends computer your going to need his ip address in order to connect to the server and view the pages

v_Ln

make sure all ur file are in the htdoc folder or document root (if u change it) in apache folder...
