Default PHP & Apache problem

Hello Mac Users,

I am very new user of mac system (about 3 weeks) and happy to use it so far.
I am a web developer and I found that Mac OS X has Apache/PHP built-in.
So I enabled and start working on local computer.
However, when I try to use a sample code from a web site,

http://www.skypaint.com/gavin/code/

(download and running in local computer)

it does not showing any output.
I tested on the Windows machine w/IIS5, but it's working as intended.
Anyone have idea how to fix this? either need to upgrade Apache or PHP?
Please help.

thanks.

I would download and use MAMP, I never got the included Apache/PHP working properly. MAMP is just a single application that starts Apache, PHP and MySQL in one go.

I'd say the problem is the version. You probably need to upgrade.
But I agree MAMP is the best option.
