This is not entirely true though. mysqlnd will return native types
through PDO or mysqli if you use prepared statements [1] and hopefully
other queries someday. [2]

As for your example, I think that this usage is within the realm of
data validation rather than type checking. The only thing I expect
from type checking is to answer this question: "is it an int? Y/N" And
that's where the schism is; the "strict" side wants type checking
to... well, check the PHP type of a variable. The "weak" side wants to
check the contents of a variable.
