----
empty($var) is a shorthand for
((isset($var) and $var == FALSE) or !isset($var))
[note there is type casting going on with the ==]
which is something that I do *very* frequently as I pass around strings of HTML and arrays full of
data and do various things if the string or array "has something in it". Since I often
don't know whether a variable is going to be defined yet, this would be a big pain without
empty().
