syntax, 3 or 4?

Hello, Can anyone clarify if this code below is indeed PHP v4 or 3? It will save significant rigmarole. Where can I find online documentation for v3? I have this 'PHP 4 Bible' by IDG Books, but it's for the version the name suggests. Many thanks Paul. > What version of PHP do you have?
