yes, but that assumes you have a defined class. if $a comes from
mysql_fetch_object() for instance you have just a stdobject, and this
method will produce an error.

the test i need should give the following results:
- FALSE when $a-b does not exist at all
- TRUE when $a-b = null
- TRUE when $a-b = any value
empty() gives true for both $a-b = null and not setting any value, so
that's no good.
borokovs suggestion seems to miss the purpose.
anyone else?

Maybe if you tell us exactly what you wish to achieve.
Class variables that are not created at object creation is bad design.

It's common mistake what you are doing...
the first thing should be to test if there is such key in array:
if (array_key_exists('cmd',$_POST))
{
}
this means to test it the variable exists, then you can test if it was set

that's a different issue.
There are always at least 2 things you should do with your (expected) input:
1 - check if it *exists* (isset)
2 - check the validity (input-validation)
for step #2 empty is very commonly used, and also a
