switch case ค่ะ เกิดอะไรขึ้น ทำไมถึง แยก case ไม่ได้ขอคำแนะนำด้วยค่ะ

mysql_select_db("sigdb",$link);
	$sel = "select count(Filename) as newvalue from preupload where servname ='uuu9'";
	$query = mysql_query($sel)or die;
	
	while($result = mysql_fetch_row($query))
	{
		switch ($result['newvalue']) {
			case $result['newvalue'] == "3":
				echo"id=1";
				break;
			case $result['newvalue'] == "8":
				echo"id=2";
				break;
			default:
				echo "test";
				break;
		
		}
	}

$sel = "select count(Filename) from preupload where servname ='uuu9'";
$query = mysql_query($sel)or die;
while  ( $result = mysql_fetch_array($query)){
switch ($result)
    {
       case "3":
           echo"id=1";
            break;
        case "8":
            echo"id=2";
            break;
        default:
            echo"test";
            break;
         }
