http://askubuntu.com – I'd like to use php includes to streamline the process of making a few web pages. The problem with that, however, is that I can't seem to test them locally. They work fine on the server, but my computer doesn't seem to understand them. I tried installing php and apache but it didn't seem to work. What do I need to do to set up a php testing server locally? (HowTos)
