Re: [PHP4BETA] Child function never get called

This is strange, the example i gave you actually echoes 2... But in the real program which is a bit more complex, it dont work, the child function dont get called. I saw some cvs info about iheritance with included files, all my classes are separate includes, could that have something to do with it? In that case, is it possible to get it? I would really need it :) Thanks, Johan Isacsson On Mon, 26 Jul 1999, Andi Gutmans wrote: > I'll take a look at it.
