New Comment:
Indeed.. 2nd issue not ok, message confusing, accepted.
1st issue:
Found this is working on my 2nd PC, not on first. Difference: working
one is running zend optimizer 2.5.0, other is 2.5.2. Disabled 2.5.2
optimizer and bounced apache, now this machine is working, too.
Assumption: zend optimizer 2.5.2 is broken- what am I supposed to do?
Thanks,
Andi

On the first item: empty($$var) evaluates correctly, recheck your test
script to be sure you didn't typo somewhere.
On the second item: This is expected behavior. empty() is not a
function, but rather a language construct which specicically expects a
real variable and not a function return value. I'll certainly grant
the error message is confusing, but no more confusing than PHP4's
version of this error:
Parse error: parse error, unexpected T_STRING, expecting T_VARIABLE or
'$' in /cvs/php4/28752.php on line 15
