Description:
------------
if i toggle something like this it doesn't give me the result i would suspect to get:

$dateTime is a mysql datetime string like :'0000-00-00 00:00:00'

Wich should be equal to empty and not null


Reproduce code:
---------------
$dateTime = '0000-00-00 00:00:00';

if(empty($dateTime)){
  $dateSet = false;
} else {
  $dateSet = true;
}

var_export($dateSet);





Expected result:
----------------
// $dateSet = tue; wich i believe should be false

false

Actual result:
--------------
// $dateSet = tue; wich i believe should be false


true
