How to PHP appendChild in an ID?

Question

I'm trying to append an associative array in my page. I searched a lot in here but when I try their answers it copies my page as many times as there are values.

Here is my code :

$reponse = $bdd->query('SELECT nom FROM `scores`');

while ($donnees=$reponse->fetch(PDO::FETCH_ASSOC)){
    foreach($donnees as $clef => $valeur){

        $html = file_get_contents('tableau.php');
        libxml_use_internal_errors(true);
        $doc = new DOMDocument();
        $doc->loadHTML($html);
        $descBox = $doc->getElementById('noms');
        $appended = $doc->createElement('li', $valeur);
        $descBox->appendChild($appended);
        echo $doc->saveHTML();

    }
};

How can I do this without my page being multiplied ?

Answer 1

You must make loop only at part where li is created and appended:

$html = file_get_contents('tableau.php');
libxml_use_internal_errors(true);
$doc = new DOMDocument();
$doc->loadHTML($html);
$descBox = $doc->getElementById('noms');

$reponse = $bdd->query('SELECT nom FROM `scores`');
while ($donnees=$reponse->fetch(PDO::FETCH_ASSOC)){
    foreach($donnees as $clef => $valeur){
        $appended = $doc->createElement('li', $valeur);
        $descBox->appendChild($appended);

    }
}

echo $doc->saveHTML();
