You can't do that, NULL is a perfectly acceptable value to pass into a
function, you wouldn't be able to know when you wanted to pass NULL or
use the default value, e.g.:

function fn1($a =3D false, $b =3D nul, $c =3D 1)
{
  var_dump($a, $b. $c);
}

// your idea
fn1(NULL, NULL, 10), // NULL, NULL, 10

// vs. using a reserved word
fn1(default, default, 10), // FALSE, NULL, 10

Cheers,
