It would be useful to be able to omit function arguments and have the function still use the defaults even though some to the right were passed:

e.g.

function fred ($a,$b=1,$c=2,$d=3)
{
echo "a=$a,b=$b,c=$c,d=$d";
}


fred(-1);
fred(-1,,4,5);

This was submitted before and respectfully declined. If you want to use something like this, you can either use an array based approach or use func_get_args().

Although your suggestion is appropriate for new code upgrading old libraries and then all the code that calls them makes it impractible for updates to existing code?
