why don't you test it.

$a = array();
$b = array(null, null, null);
$c = array(false, false);
$d = array(1, 1, 1);

echo "array \$a: \n---------------------------\n";
var_dump(empty($a), count($a), array_filter($a), array_values($a));
echo "array \$b: \n---------------------------\n";
var_dump(empty($b), count($b), array_filter($b), array_values($b));
echo "array \$c: \n---------------------------\n";
var_dump(empty($c), count($c), array_filter($c), array_values($c));
echo "array \$d: \n---------------------------\n";
var_dump(empty($d), count($d), array_filter($d), array_values($d));
