Actually isset() doesn't behave as it should:
$foo = null;
echo isset( $foo );
In the above it should return true, but doesn't because it considers
null to be not set. Thus it is flawed since I explicitly set it to null.
Understandably this is documented; however, the issue here is whether a
variable_exists() function should be added -- for which I am +1 for
adding it :)
Cheers,
Rob.
