Re: Re: variable_exists() patch

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.
