This simple shorthand seems to work for setting new variables to NULL:
<?php
$Var;
?>
The above code will set $Var to NULL
UPDATE: After further testing it appears the code only works in the global scope and does not work
inside functions.
<?php
function Example(){
$Var;
var_dump($Var);
}
?>
Would not work as expected.
