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! :-) )
