I just did a fresh install of Redhat Enterprise V4 along with Apache 2 and mySQL that came with the install. I purposely did not install any PHP as the version that comes with the package (It's version 4; I need to install version 5).

My overall intent is to put a LAMP server together. Can anyone point me to website or provide instructions on how to get PHP 5 on my box? Or do I need to reinstall ALL/SOME the components individually to do this? Most of the sites I'm finding indicate that I need to install Apache along with PHP.

OR if you know of a simple "step by step" method of install for building a LAMP server, that would also be great! I am very new to the Linux world; may of the instructions Ive found on the Internet are either convoluted, are imcomplete, or cover old versions of PHP.

Any help is very much appreciated!

Take a look here. Its not current but it should be alright for the latest amp versions.
