[peter279k]

Here is the code snippets with PHP:

function likes( $names ) {
    $namesCount = count($names);
    if ($namesCount === 0) {
        return "no one likes this";
    }

    if ($namesCount === 1) {
        return sprintf("%s likes this", $names[0]);
    }

    if ($namesCount === 2) {
        return sprintf("%s and %s like this", $names[0], $names[1]);
    }

    if ($namesCount === 3) {
        return sprintf("%s, %s and %s like this", $names[0], $names[1], $names[2]);
    }

    if ($namesCount >= 4) {
        $likesStringFormat = "%s, %s and %d others like this";

        $otherNamesCount = $namesCount - 2;

        return sprintf($likesStringFormat, $names[0], $names[1], $otherNamesCount);
    }
}
