Загрузить итерацию по массиву в PHP

Question

Я использую виджет многозадачности Uploadcare и возвращаю идентификатор группы на пост. Когда я вызываю API для перечисления файлов в группе, я хочу извлечь определенные фрагменты информации о каждом файле (uuid, mime_type, original_filename и т. Д.).

Вот мой код:

$privateFiles = $_REQUEST['privateFiles'];  
$ucApi = new Uploadcare\Api(public_key_removed, private_key_removed); 
$group = $ucApi->getGroup($privateFiles); 
$files = $group->getFiles();   

foreach ($files as $ucFile) 
    { 
     echo $ucFile['uuid']; 
    } 

Когда я пытаюсь сделать это, я получаю эту ошибку: Fatal error: Cannot use object of type Uploadcare\File as array

Я определенно получаю данные обратно из API, но только имеющие проблемы пытаясь разобрать его. Вот пример того, что я получаю обратно:

Answer 1

Uploadcare\File является объектом, так что вы должны относиться к нему как один.

Чтобы получить UUID, существует способ: $file->getUuid().

Для других мета-данных вы можете usedata массив:

foreach ($files as $file) 
{ 
    echo $file->getUuid(); 
    echo $file->data['is_image']; 
    echo $file->data['datetime_uploaded']; 
    // etc 
}
