Definiately go with an Apache/PHP3(4)/MySQL combo. If you go to opensource.org, you can download a binary distribution of Apache which is SSL-capable and installs PHP4 for you at the same time. All you have to do is enter you host name and email address when the setup proceedure prompts you, and you should be up and running. If you've neer used MySQL before, try grabbing this once the Apache, PHP, and MySQL are all nicely settled in their new homes on your machine:

It's a web-based MySQL administration program that allows you to run everything you can from the command prompt. Hope this help!
