这应该是可能的，但它不是。

不应该，因为在 data 中有一个对象，而不是数组。 （和 data 本身也是一个对象的属性。）

对象属性通过 - > in PHP。

  $ foo ['VGardena']  - > data [0]  - >消息
  

I need the message part of the json-string below. It should be possible with this, but it isn't.

echo $fb_response['data'][0]['message'];

解决方案

It should be possible with this, but it isn't.

No it shouldn’t, because you have an object here inside data, and not an array. (And data itself is also the property of an object.)

Object properties are accessed via -> in PHP.

$foo['VGardena']->data[0]->message
