PHP - How to sort values from a lottery table

I have the following problem: "Imagine we have the records of a lottery, but we need to sort the values. I already tried the documentation code for php - asort , but it does not work! I'm using the 7.2.4 version of php (hope you do not have a bug!)

Database:

Iwanttosortthenumbersthatareinn1,n2,n3,n4,n5andn6.

Ex:id=2032,itshouldhaven1=6,n2=14,n3=19,n4=20,n5=39andn6=53.

Code:

$result=mysqli_query($db,"SELECT * FROM table32");
while ($dados = mysqli_fetch_array($result, MYSQLI_BOTH)) { 
    $valores = array(
        "n1" => $dados['n1'], "n2" => $dados['n2'], 
        "n3" => $dados['n3'], "n4" => $dados['n4'], 
        "n5" => $dados['n5'], "n6" => $dados['n6']
    );
    asort($valores);
    foreach ($valores as $n => $val) { 
        echo "$n = $val"; //Não chega aqui! 
    } 
}
