Apache is pretty easy to install, you can download it in a MSI package. Your subject was PHP server, so I'm assuming that you also want to install and configure PHP for your server as well...
Apache and PHP are a great combination, although if you're going to do this then download Apache version 1.3.26, because the newer version is somewhat more difficult to install PHP with.
KF Web Server is a free HTTP Server that can host an unlimited number of web sites.
Its small size, low system requirements and easy administration make it the perfect choice for both professional and amateur web developers alike.
Implements the latest HTTP standard, 1.1 to provide request pipelining, range downloads and browser cache support for enhanced performance.
Works great with PHP, PERL, Python and other scripting languages.
Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
