Much appreciated, I'm running 5.2.5 locally, if I recall correctly so is my server and I want to make this backwards compatible atleast to an extent, so I think I'll go with call_user_func().

In this case though wouldn't I want call_user_method()? I remember glossing over that in one of my reference manuals, IIRC it said they acted the same... I'll give it a go here.
