Hi.

I am trying to extend SplObjectStorage and override the attach() method. 
This gives me:

Strict Standards: Declaration of B::attach() should be compatible with 
that of SplObjectStorage::attach() in test.php on line 5

Seems am am hitting the object type hint wall again. Any ways around 
this, aside from disabling strict standard notices?


Regards,
Karsten

well, and what is the reason why you can't make your "attach()"
compatible with SplObjectStorage's?

the following signature works for me (both in 5.2 and 5.3):
public function attach($obj, $inf = null)

Doh, well. Even better, so it's not some "object" type hint, but simply 
me not knowing the full attach() signature. Yay!

Thanks a bunch!
Karsten

PS: Some updated docs for SPL would be really cool... ;)

try this (with CLI php):
php --rc SplObjectStorage
