Hi Steve,
0 and "foo" are two different types (int and string). In order to compare
these values they must be converted into the same type. PHP does that by
converting "foo" to an integer and that value will be 0, hence the true
value on compare with ==. when you use === to compare the two values need
to be of the same type to evaluate to true.
you can trick the compare by doing stuff like this:
if ("$key" == "muppet") (
}
