Re: PHP 7.1 - Address PHPSadness #28?

Yes, because all undefined variables in PHP are implicitly null. As far as PHP is concerned, if it's null, it's by definition _not defined_. Also, still not seeing where a NOTICE is involved here? Those functions never give errors. What is the usefulness of a function that merely returns true when a variable is null?
