Well, my guess was wrong. I guess it has to happen eventually. :)
So how are you calling the function? If you have:
function func($a=1,$b=2)
{ print("[$a]"); }
func();
all by itself, does it work? No reason it shouldn't. Maybe you think you're
passing a value to func(), but you're really not. In order to get what you
say, you _have_ to be passing an empty string as the first parameter.
Wait... you realize that if you call
func('');
That $a in the function will be an empty string, right? $b would get the
default value of 2. They would only get that default value if you do not
include that parameter in the function call at all.
