Hi I found a function declaration in an open source project (in php5) and I could not find documantation for this. The function declaration is: public function registerComp(IComp $comp) Is it a kind of typecast?

no its a type declaration (is that the correct term). it states that $comp must be an object of class IComp (or a subclass of it). if $comp is not anj IComp object you get a fatal error. this only works for classes. and it does not work in conjunction with optional params e.g: public function registerComp(IComp $comp = null) { /*....*/ } (which IMHO sucks but hey c'est la vie! :-) )
