I've got a function that starts off like this:

function alphabeticalListOfAlbumsByLetter($whichLetter="a") {

}


I pass in the letters (a, b, c, d, etc) and the numbers (0, 1, 2, 3,
4, etc). It finds in the database records starting with that letter or
number. It works fine except when I try to pass in a zero. The PHP
code acts as if I have not passed in a function argument, so
$whichLetter becomes "a", which is the default value (as you can
see).

So how do I get PHP to see that I'm really passing in a zero, and not
just some false value?
