Hello Cristiano,
First, I'd like to say that a function of this type sounds useful.
It's one that I've wanted for some time, particularly for verifying
that an array has the correct keys when it is passed as a function
parameter.
If I understand what you are doing correctly, the same thing can be
accomplished by:
array_intersect(array_keys($records), array(234, 567, 890, 123))
However, I agree that array_diff_key() and array_intersect_key()
would be significantly useful functions to add to the core.
