Hello Jochem,

sorry, I didn't tested the code at all, because my code is more complex.
I just tried to show the problem.
class ClassA {
public static function getClassName() {
return get_class($this); // [1]
// or [2] return get_class(self);
// or [3] return __CLASS__;
}
}
class ClassB extends ClassA { }
echo ClassB::getClassName();
I am searching for a function to use in line [1] so that the script's
output is "ClassB".

my fault, again, sorry. I jumbled the different outputs. I understood
that this behaviour is coherent.

that's true. I don't want to use this. I just checked it.

is better. but it seems that even debug_backtrace() is not what i'm
looking for...

no, no generic code. ;)
