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(). -- http://www.php.net/manual/en/function.empty.php http://master.php.net/manage/user-notes.php?action=edit+26691 http://master.php.net/manage/user-notes.php?action=delete+26691 http://master.php.net/manage/user-notes.php?action=reject+26691
