Non-strings equate to a boolean value of 1 when they are converted to a
boolean value automatically (in the case of comparison queries) when
they contain a value. Strings of 0 length are converted to a 0. In
useful terms, 1 is true and 0 is false in the PHP world. As PHP is a
loose-typed language you should really use the === operator if you need
to compare variable mathc and type match.
