Status: Bogus
Type: Bug
Package: Class/Object related
Operating System: linux
PHP Version: 5.3.3

New Comment:
Close it if you wish, but I do honestly believe this is a major bug...
This means that you cannot trust that $this is an instance of the class
it's
used in. So does that mean that we must add:
($this instanceof self) or throw new Exception('called from another
class');
to all of our methods?
Remember, any sufficiently advanced bug is indistinguishable from a
feature (no
matter if it is documented or not). But don't be afraid to call it what
it
really is... Just because it's documented, doesn't mean it isn't a
bug...
Again, IMHO...

Closing as bogus. As you have pointed out, this is documented.

It has been pointed out to me that this is actually documented:
http://us2.php.net/manual/en/language.oop5.basic.php
Under example 2 and specifically the lines:
$b = new B();
$b->bar();

Can reproduce across architectures & versions from 5.2.9 onward, IMHO
opinion, just an E_STRICT error in between is understating the scripters
design flaw. Some existing code may rely on it, so a real fix may hurt
some packages, but at the very least I'd increase the errors severity.

Oh, and $this is an object of class Test2 within Test1::getName()...

This seems to have existed way back in PHP 4.1:

If this is a bug, then I think it should be turned into a feature and
documented. It is occasionally useful for trait-like functionality.
