I think it's good to point out that is_bool() is the exact opposite of empty() and that
is_bool() will return false if the variable it is checking is one of the following...
$x = "";
$x = null;
var $x; (not set)
$x = array();
$x = false;
$x = "0";
$x = (int) 0;
Empty returns true for all of those. It's useful instead of typing !empty() and worrying.
