PHP switch statement returns invalid output

Question

The PHP switch statement returns invalid output :

$cond = "Night";

switch($cond){
    case "Morning":
    case "Night":
        $name = "Good";

    case "Morning" :
        echo $name." Morning";
        break;

    case "Night" :
        echo $name." Night";
        break;
}

Output: Good Morning

Expected: Good Night

Can someone help me with this?
