It is indeed. "I know it's name but it doesn't exist", however, is generally not a valid state - if you've hard-coded the name (as is the case with 99.9% of bare variables) then clearly you consider it to have some existence. For this reason, PHP assumes that you meant to create it with a null value. I seem to remember Perl has an interesting quirk along these lines where in some circumstances just reading from a variable will actually initialise it in memory!
