Complete rubbish -- it so absolutely is!

If $a===$b, then !($a===$b) is the same as $a!==$b, QED.

Well, you haven't covered all bases there, you've got INTEGER===true in twice!

Try this:

    (integer)===TRUE  -- is always FALSE
    (integer)!==TRUE  -- is always TRUE

    (integer)===FALSE -- is always FALSE
    (integer)!==FALSE -- is always TRUE

Looks seriously like two sets of complementary results there to me.

True.

False, false, false, and a thousand times false.  If $a===$b returns TRUE, then $a!==$b returns FALSE; and if $a===$b returns FALSE, then $a!==$b returns TRUE.  I don't know how much more opposite you can get.

Cheers!
