MySQL查询遍历多个变量

Question

I'm trying to display a variety of results with a mysqli query and i feel like i am using up too much code. I'm wondering if anyone can tell me if i can loop through multiple variables.

For the example i have multiple Agents and Multiple columns for the agents wich are equal for all the agents. I want to run the query so it will cycle through all the columns for and agent then output the data and then move on to the next agent and do the same

echo "<table>
<tr><th>Van</th><th>Aantal</th></tr>";

$sql = ("SELECT SUM(Case_closed) as sum_closed FROM productie WHERE Agentnaam='Agent1' ");
    $result = mysqli_query($connect, $sql)  ;
            $Case_closed = $result->fetch_object()->sum_closed;

echo "<tr><td>Cases closed</td>";
echo "<td>$Case_closed</td></tr>";

$sql = ("SELECT SUM(Case_handled) as sum_handled FROM productie WHERE Agentnaam='Agent1' ");
    $result = mysqli_query($connect, $sql)  ;
        $Case_handled = $result->fetch_object()->sum_handled ;

echo "<tr><td>Cases handled</td>";
echo "<td>$Case_handled </td></tr></table>";

I found the solution with : Foreach

  $connect = new mysqli ('localhost', $username, $password, $database);
if (!$connect) {
    die('Could not connect: ' . mysqli_error($connect));
} else {

    $normal_array = array('Agent1','Agent2','Agent3');
    foreach($normal_array as $value){


    $s = "SELECT * FROM productie WHERE Agentname='$value' AND Date='$actual_time'"; 
    $result = mysqli_query($connect,$s);
    $row = mysqli_fetch_row($result);



    Echo "</br></br><table><tr><th>$value</th><th>Ammount</th></tr>";

    Echo "<tr><td>Cases closed      :</td><td> " .$row[2].       "</td></tr>";
    Echo "<tr><td>Cases handled     :</td><td> " .$row[3].       "</td></tr>";
    Echo "<tr><td>another column    :</td><td> " .$row[4].       "</td></tr>";
    Echo "<tr><td>another column    :</td><td> " .$row[5].       "</td></tr>";
    Echo "<tr><td>another column    :</td><td> " .$row[6].       "</td></tr>";
    Echo "<tr><td>another column    :</td><td> " .$row[7].       "</td></tr>";
    Echo "<tr><td>another column    :</td><td> " .$row[8].       "</td></tr>";
    Echo "<tr><td>another column    :</td><td> " .$row[9].       "</td></tr>";
    Echo "<tr><td>another column    :</td><td> " .$row[10].      "</td></tr></table></br>";
