Now hand him what "===" means :-)

I just stepped in from and haven't read the history of this thread.
However, just from this little bit I can see that he doesn't know
programming at all. I'll bet he even thinks that

$a = 11;

means that the variable $a is equal to 11 and that this is an equation.
(Hint August: It isn't an equation. It is an expression that you are
taking the value 11 and setting the value of 11 into to the memory
location denoted by the variable $a).

Programming != mathematics.

Anyway, perhaps August should pick up a book on C, C++, Java and see
what they use for tests of equality before he criticizes PHP.
