Local only Apache intall?

[goldenGoddess?]

My friend wants me to install apache on her machine with php so she can start learning how to write php. The problem is that she uses an wireless connection from her landlord's house and we can't access the router. Is it possible to install apache but keep it local? Its only for testing and practice so she doesn't need much, just access from her local network (she has 2 windows and a mac machine running off her wireless connection that she would like to test) Any help would be excellent. She wants to install it on xp

Ok Ok, nevermind, I was being lazy, I found on Apache's website:
Select only for the Current User, on Port 8080, when started Manually if you'd like to install Apache for your personal experimenting or if you already have another WWW server running on port 80.
Sorry for my inaptitude ;)

Also, in the httpd.conf file, get rid of all "Listen" lines and add just one like so:

Listen 192.168.0.100:80

Replacing '192.168.0.100' with your friend's internal IP. This would only allow users inside the network to access it. If the router isn't forwarding port 80 to her computer, however, it's probably not necessary.
