Is it possible to account/trap missing arguments in functions?
For instance, say I have a function foo:
function foo($arg1,$arg2) { blah }
If someone calls that function as:
foo($arg1);
Can I somehow code around the fact that $arg2 is missing? I've tried:
function foo($arg1,$arg2) {
if (!isset($arg2) { $arg2=0 }
}
But that doesn't work. However, that's the sort of functionality I'm looking
for -- is there a way to do it?
Thanks.
