可以使用project进行加工处理，代码如下：
<?php
$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");
// 插入数据
$bulk = new MongoDB\Driver\BulkWrite;
$bulk->insert(['x' => 2, 'name' => 'bfw', 'scores' => 123, 'atime' => time()-1000000]);
$bulk->insert(['x' => 2, 'name' => 'google', 'scores' => 10, 'atime' => time()-200000]);
$bulk->insert(['x' => 2, 'name' => 'baidu', 'scores' => 11, 'atime' => time()-1231123]);
$bulk->insert(['x' => 2, 'name' => 'bfw', 'scores' => 200, 'atime' => time()]);
$bulk->insert(['x' => 2, 'name' => 'bfw', 'scores' => 123, 'atime' => time()]);
$bulk->insert(['x' => 2, 'name' => 'google', 'scores' => 10, 'atime' => time()]);
$bulk->insert(['x' => 2, 'name' => 'baidu', 'scores' => 11, 'atime' => time()]);
