isset(): generally spoken, returns true if a variable is _defined_,
regardless of it's actual value:
isset($myvar) => returns false
empty($myvar) => returns true
$myvar = "something";
isset($myvar) => returns true
empty($myvar) => returns false
$myvar = "";
isset($myvar) => returns true
empty($myvar) => returns true
unset($myvar);
isset($myvar) => returns false
empty($myvar) => returns true
My advice: avoid comparing to false or true (and since these are constants,
don't put them in quotes ;->).
// bad way
if (isset($myvar) == false)
// better way
if (!isset($myvar))
