Maybe I am then misunderstanding your proposal, as to me it is clearly =
covered and deemed not possible:
http://wiki.php.net/rfc/ifsetor#rejected_features

$var =3D ifsetor($var, $var2, "admin");
However this is currently not possible to be implemented without major =
slowdowns to the engine.
