Within a class function I have defined another function for use with the
usort() function. How do I reference it?

When it's not part of a class usort($arr,"cmp") works fine but when it's
within a class function I get this error:

PHP Parse error:  syntax error, unexpected T_STRING, expecting T_FUNCTION

Is it not in the scope of the class function?

you need to use an array to describe the callback function:

class Foo
        public function cmp($a,$b)
                // do comparison and return result


$foo = new Foo();

I think that's right - doesn't the manual describe this sort of thing about using callback functions that are class members?
