Bonjour

Après plusieurs réflexiosn, j'ai trouvé je pense une solution afin de trouver le bon syntaxe mais je ne sais pas si cela peux se simplifier car je commence par récupérter la ligne qui possède un '' ensuite j'appel la function, je ne peux aps passer directement par la fonction récurcivement*. Je doit passer uen fois le prmeier manuellement.....

quel est votre souci si vous commencez directement par le code suivant ?

Code:

$data = afficherTree($bdd, $i, "");

Code:

echo json_encode($datas[0]);

au lieu de :

Code:

echo json_encode($datas);

Le code est correct mais les indices ne sont pas correct ....

Merci

à quoi correspond cette information "id" ?
s'il s'agit d'un identifiant unique, je vois seulement 2 possibilité. soit l'élément à déjà un identifiant dans la base de données et donc cette valeur peut être récupérée.
ou alors cet identifiant est créé dans votre code et dans ce cas l'ordre n'a pas d'importance tant que l'unicité est respectée.
