a couple of potentially useful helpers

i created that helper quite awhile ago when i was getting errors passing nulls into the empty function. It was quite irritating, so basically it was put in as a work around for the problem. Still to this day not sure why i was getting that error with the empty function but yeah, that is why i wrote it.

You might've had problems with passing function return values directly to empty():

PHP Code:

// This only works on PHP 5.5+
empty(foo()); 


This has nothing to do with nulls though.
