<?php

// 1.創(chuàng)建數(shù)據(jù)庫連接對象

$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");

// 2.設(shè)置查詢條件，返回鍵，排序規(guī)則

$filter = ['index' => ['$gt' => 1]];

$options = [

'projection' => ['_id' => 0],

'sort' => ['index' => -1],

];

// 3.創(chuàng)建查詢對象

$query = new MongoDB\Driver\Query($filter, $options);

// 4.指定查詢的數(shù)據(jù)庫中的集合，查詢test庫的sites集合

$cursor = $manager->executeQuery('test.sites', $query);

// 循環(huán)遍歷查詢的結(jié)果

foreach ($cursor as $document) {

// 調(diào)用將對象轉(zhuǎn)換為數(shù)組函數(shù)

var_dump($arr['name']);

/**

* 對象轉(zhuǎn)換為數(shù)組

* @param object $object 需要轉(zhuǎn)換的對象

* @return array 轉(zhuǎn)換后的數(shù)組
