Re: Class Properties in Interfaces?

So you are saying that

       $o_Foo->bar = array(42);

is ok when the class "expects" a string but

       unset($o_Foo->bar);

or (as as slight variation)

       $o->Foo->bar = null;

is not?

I Do not get the connection here? And since when can we 'expect' a string only for a property?

You stated that allowing unset() is a bug. I replied that unset() is not different from setting the value to array(42) or null and should be allowed. Apropos 'expect': A programmer of a class can have some expectations of what is stored in attributes, PHP does not enforce these expectations (hence I put expect in quotes). And just to make it clear: I want to keep it that way, I do not want PHP to become more strict than it is. So I completely agree with Stas here. - Chris
