讀資料

使用方法jsonSerialize()，如

$image->feature->jsonSerialize();

寫資料

通過Binary建構函式

$data['feature'] = new Binary($res['feature']['$binary'],$res['feature']['$type']);

一個寫例項

public function parseAction($json_data,$connection)
{
    $res = json_decode($json_data,true);

    $data
 
['aaa'] = $res['aaa'];
    $data['bbb'] = $res['bbb'];
    $data['ccc'] = $res['ccc'];
    $data['feature'] = new Binary($res['feature']['$binary'],$res['feature']['$type']);

    $image_db = $connection->selectCollection('t_image');
    $insert_result = $image_db->insertOne($data);
    if($insert_result
 
->getInsertedCount() < 1){
        echo 'insert failed';
    }else{
        echo 'insert success';
    }
}
