From the docs for empty(): "Note that this is meaningless when used on anything which isn't a variable; i.e. empty (addslashes ($name)) has no meaning since it would be checking whether something which isn't a variable is a variable with a FALSE value. "

Maybe I am not so clever, but the document writer tried to explain that empty()'s flaw is a feature. The correct doc should contain lvalue instead of variable. -- jul
