Comment afficher les données de la base de données avec un rowspan dynamique

Tout d'abord désolé pour mon mauvais anglais.

Dans votre requête, au lieu de trier par id_location , effectuez un ordre par nom de composant . De cette façon, vous pouvez facilement ajouter une étendue de lignes dynamique. Je n'ai pas changé votre programme de connexion, mais j'ai changé votre deuxième partie. Vérifiez s'il vous plaît. Je sais qu'il y a 3 à 4 boucles. Mais si quelqu'un a trouvé un meilleur algorithme, merci de me le dire.

    $sql1 = "SELECT * FROM Lokasi ORDER BY id_location";
    $stmt1 = $dbc->prepare($sql1);
    $stmt1->execute();

    while ($row1 = $stmt1->fetch(PDO::FETCH_ASSOC)) {
    $location++;
    echo "Location $location : ".$row1['location'];

?>



<?php
    $query = "SELECT * 
                FROM sub_component,
                     component 
               WHERE sub_component.id_component=component.id_component 
                 AND component.id_location='$data[id_location]' 
            ORDER BY component.component_name";
    $stmt = $dbc->prepare($query);
    $stmt->execute();

    # Declare two emty array
    $component     = array(); # Will store the components
    $sub_component = array(); # Will store the sub components

    $loop = 0;

    # Now if any data is fetched from previsous query, then fill
    # the above declared arrays.
    while ($row = $stmt->fetch(PDO::FETCH_ASSOC)) {

        $component[$loop]     = $row['component'];
        $sub_component[$loop] = $row['sub_component'];

        $loop = $loop + 1;
    }

    # If no data fetched then I m telling 
    # No data fetched.

        echo 'Empty Data';

            # Then we will store them as following.
