PHP - 訪問JSON數組

我想訪問我的JSON數組中的值。這是我的PHP代碼來獲取JSON內容：PHP - 訪問JSON數組

$input = @file_get_contents("php://input"); 
$event_json = json_decode($input); 
$event = \Stripe\Event::retrieve($event_id);

這是輸出：

Stripe\Event JSON: { 
"id": "evt_6WV8LzHBPwRYW4", 
"created": 1435683755, 
"livemode": false, 
"type": "charge.succeeded",

} 
} 
}, 
"object": "event", 
"pending_webhooks": 1, 
"request": "iar_6WV8y99x1gReuF", 
"api_version": "2015-06-15" 
}

具體而言，我希望訪問data->metadata->product值 - 在本例中是「定金」

這是我正在試圖訪問它：

$event->data->metadata->product;

雖然這回報空白。

我在做什麼錯？

有一個對象的屬性下的數據：'$事件 - >數據 - >對象 - > metadata-> product'。在'$ event'上執行'print_r（）'來查看結構。 – AbraCadaver

@AbraCadaver不知道我怎麼會錯過這個。這是解決方案。你介意把它作爲答案嗎？ – oliverbj

data下有object財產。請在$event上執行print_r()查看結構。

用途：$event->data->object->metadata->product

可以在print_r()看到：

stdClass Object 
(
    [id] => evt_6WV8LzHBPwRYW4 
    ..... 
    [data] => stdClass Object 
     (
      [object] => stdClass Object 
       (
        ..... 
        [metadata] => stdClass Object 
         (
          [product] => deposit 
         )
