Description:
------------
I would kill for a way to do isset && check if the value is s specific data type such as numeric.  My code is loaded with if(isset($a) && is_numeric($a)).  It would be nice to do that in a single function (isset($a,[is_numeric])).

Thank you taking the time to read my request.

Expected result:
----------------
$var = isset($a,[is_numeric]);

$var = true,false

Actual result:
--------------
$var = isset($a,[is_numeric]);

$var = true,false

I learned you can bypass the warning with the reference to a variable

function bob(&$fred)

wont give me the notice of undefined variable.  My Bad.
