使用PHP计算Json元素

所以我有

{
"members": [
    {
      "username": "John",
      "status": "offline",
      "avatar_url": "...",
      "id": "830232882252102064"
    },
    {
      "username": "Momo",
      "status": "online",
      "avatar_url": "...",
      "id": "259137993351102464"
    }
  ]
}

---

我如何计算（在php中）有多少用户处于脱机状态，有多少用户处于联机状态，并将它们返回到一个值，如

$memonline

和

$memonline

，在下面的代码中，我们将获得所有

状态的值，然后我们将
计算所有状态的值
