Which version to test?

[ipscone]

I am on a system that has PHP 4.

I want to test the Lite version to make sure I can get it installed on my system.

There are two versions.

One with "PHP" extensions and
One with "PHP 3" extensions.

Which should I test to make sure it will install correctly with my system that has PHP 4?

Thanks
