@ircmaxell: No, you don't need to modify all your code and add that
line. Or at least you don't need to do so if you don't already have this
line in every method:
if (!isset($this)) throw new LogicException('Called non-static method
statically');
In PHP you can't rely on $this being set. But still you do, because an
unset $this is a real edge case.
But I still do think that this feature *is* a bug and shall be removed.
It is absolutely illogical that $this isn't instanceof self.

Does it really mean you must put that line in every method? It's not
like you ever accidentally had a problem with it before is it?

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.
