If what you want to do is avoid the notice, then you don't need to "find out before
calling is_null", you need to call isset *instead of* is_null. Again, ignore the

BUT ISSET RETURNS FALSE FOR A VARIABLE THAT IS SET BUT NULL ... END OF
STORY ...
AND SO DOES IS_NULL
The notices emitted by is_null are COMPLETELY IRRELEVANT.
