While researching for this suggestion I found this rfc proposal regarding
ifsetor() ( http://wiki.php.net/rfc/ifsetor?s[]=3Disset<http://wiki.php.net=
/rfc/ifsetor?s%5B%5D=3Disset>)
and it's rejection point was that it was currently not possible (
http://marc.info/?l=3Dphp-internals&m=3D108931281901389&w=3D2 )

But would it be possible to check for a value of a variable if it is set?

Since I often do (and see others do)

if(isset($_GET["foo"]) && $_GET["foo"] =3D=3D "bar")
or even worse
if((isset($_GET["foo"]) && $_GET["foo"] =3D=3D "bar") || (isset($_GET["baz"=
]) &&
$_GET["baz"] =3D=3D "bat"))

to be able to do something like this

if(isset($_GET["foo"]) =3D=3D "bar")
or
if(isset($_GET["foo"]) =3D=3D "bar" || isset($_GET["baz"]) =3D=3D "bat")

That isset (or some other language construct) would return the variable if
it were set and false if it was not.

Thanks for your time, i know this has probably been talked to death in one
form or other.
