Answer 1

Hey use array_values() function on your output.

$arrA = array(0 => 0, 1=>1, 2=>2 );
$arrB = array(0 => "0", 1 => "1");

$lol = array_values(array_diff($arrA, $arrB));
var_dump($lol);

Answer 2

If you want the result begins with zero, just sort it before output.

sort($lol);

var_dump($lol);
