php - 字段仅在值时回显

Question

为了避免在屏幕上打开行，我怎样才能达到 5 个 vip 字段，只有在其中有值时才会回显？

谢谢，本尼

$db = new mysqli('host', 'user', 'pass', 'dbase');
if (mysqli_connect_errno()) {
    printf("Connect failed: %s\n", mysqli_connect_error());
    exit();
}
$query = "
    SELECT
        user.FName, 
        user.LName, 
        user.HerbalifeID, 
        user.UplineS,
        registratie.PartnerFName as pfn, 
        registratie.PartnerLName as pln, 
        registratie.NaamVIP1 as vip1, 
        registratie.NaamVIP2 as vip2, 
        rgistratie.NaamVIP3 as vip3, 
        registratie.NaamVIP4 as vip4, 
        registratie.NaamVIP5 as vip5 
    FROM
        registratie 

    INNER JOIN user 
        ON registratie.userID = user.UserID 
        AND registratie.eventID =127;
";
$result = $db->query($query) or die($db->error.__LINE__);

if ($result->num_rows) {
    while ($row = $result->fetch_object()) {
        echo "{$row->FName} {$row->LName} {$row->HerbalifeID} {$row->pfn} {$row->pln}<br>
        {$row->vip1}{$row->vip2}{$row->vip3}{$row->vip4}{$row->vip5})<br><br>"; //only
    }
} else {
    echo 'No Results';
}

if(!empty({$row->vip1}) and !empty({$row->vip2}) and !empty({$row->vip3}) and !empty({$row->vip4}) and !empty({$row->vip5}) ){
    echo "{$row->FName} {$row->LName} {$row->HerbalifeID} {$row->pfn} {$row->pln}<br>{$row->vip1}{$row->vip2}{$row->vip3}{$row->vip4}{$row->vip5})<br><br>";
}else{
    echo "{$row->FName} {$row->LName} {$row->HerbalifeID} {$row->pfn} {$row->pln})<br><br>";

}
