This tutorial will not explain how
to install PHP, MySQL, or Apache Server.
If your server supports PHP - you
don't need to do anything! You do not need to compile anything or install any
extra tools - just create some .php files in your web directory - and the
server will parse them for you. Most web hosts offer PHP support.
However, if your server does not
support PHP, you must install PHP. Below is a link to a good tutorial from
PHP.net on how to install PHP5:
