将数组插入Mongo集合

Question

我试图将$ json插入MongoDB。我的想法是，对数组进行预处理/循环以仅获得＆＃39;状态＆＃39;。

$ json从另一个函数传递。看起来像这样：

{
  "statuses": [
    {
      "created_at": "Fri Apr 22",
      "id": 123,
      "text": "Sample text 1",
    },
    {
      "created_at": "Fri Apr 22",
      "id": 321,
      "text": "Sample text 1",
    }
  ],
  "search_metadata": {
    "count": 2,
    "since_id": 0,
    "since_id_str": "0"
  }
}

代码

<?php 

$m = new MongoClient();
$db = $m->selectDB("newDB");
$collection = new MongoCollection($db, 'newStatus');

// looping through $json
foreach ($json as $document){
  // another looping to get 'statuses'
  foreach($document['statuses'] as $status) {
    // store into MongoDB
    $collection->insert(json_decode($status));
  }
}

?>

修订：以上代码有效！添加$collection->insert(json_decode($document));

然而，它存储了整个数组块。我只想要＆＃39;状态＆＃39;。
