Optional By Ref Argument?

[Alan Little]

Is it possible to make a by-reference argument optional in a UDF? When I
try to assign it a default value in the definition, I get a parse error,
"unexpected '='". PHP itself has optional by-ref arguments (e.g. getmxrr);
is it not possible for UDFs?

It's possible with PHP 5, impossible (as far as I know) with PHP 4
