Donc, je suis venu à un léger problème dans la formulation de cette réponse api. Je suis en train de phrase les données de capture d'écran de cette réponse api? ..Phrasing réponse JSON en PHP
J'ai essayé le bas, mais en vain! .. Il semble juste être NULL? .. toute aide serait un grand merci
$jsonData = json_decode($response, true);
$testt = $jsonData->screenshot->data;
la réponse:
