如何访问数组中的特定对象值？

Question

我正在使用Dropbox API，所以我可以从路径构建图库，但我有点卡在这个数组中。我想从这个数组访问图像的路径值。同时将其显示为dropbox image gallary。请帮我。我有点卡住了！谢谢。

Answer 1

假设您调用此数组if shoppingList.count > 3 { shoppingList.removeAtIndex(3) } ，以获取foreach循环的图像路径：

$imagesArray

Answer 2

假设您在$ data变量中的结果超过了所有图像路径：

$imagePaths = array_map(function($image) {
    return $image->path;
}, $data['body']);

现在您在$ imagePaths变量中拥有所有图像路径。
