Il semble que j'ai un problème avec la conversion JSONArray et JSONObject. Mon PHP ressemble à ceciObjet JSON et tableau
{"list":[{"Name":"Michael","Hour":"one"},{"Name":"Johhny","Hour":"two"}]}.
Je suis en train de remplir filateurs, mais cela ne fonctionne pas, ils restent vides. J'ai vu des questions similaires mais sans bonne explication. J'espère que tu peux m'aider.
