问题描述
我正在尝试将PHP 7与mongoDB连接，我通过遵循页面说明.我可以从phpInfo()输出中看到MongoDB版本1.1.8，但是我不知道如何从PHP代码:p发起连接.以下代码包括我的连接尝试(即使使用旧的方式也尝试连接)
I'm trying to connect PHP 7 with mongoDB, I installed the "new" MongoDB driver using pecl by following this page instructions. I can see MongoDB version 1.1.8 from phpInfo() output, but I can't figure out how to initiate a connection from PHP code :p . the following code includes my attempts to connect (tried to connect even using old fashion way)
// new fashion way
$connection = new MongoDB\Driver\Client();
// or by using old fashion way
$conn = new MongoClient();
// random try :p
$randConn = new MongoDB\Client();
，在两种情况下，我都未定义类异常. 请让我知道我想念的是什么，我的错误在哪里，请提供示例，以便在可能的情况下更易于遵循；).
and in both cases, I'm getting not defined class exception. please let me know what I'm missing and where is my mistake, please provide and example to be easier to follow if possible ;) .

提前谢谢.
推荐答案
您所引用的页面是MongoDB的低级PHP驱动程序.该API与用于MongoDB的HHVM驱动程序相同.两者的文档都相同，可以在 http://上找到docs.php.net/manual/en/set.mongodb.php
The page that you are referring to is the low-level PHP driver for MongoDB. The API is the same as the HHVM driver for MongoDB. The documentation for both of them is the same, and can be found at http://docs.php.net/manual/en/set.mongodb.php
该驱动程序被编写为与MongoDB对话的基础层，因此缺少许多便利功能.相反，这些便利方法已分解为用PHP编写的层， MongoDB库.使用该库应该是与MongoDB进行交互的首选方法.
The driver is written to be a bare bone layer to talk to MongoDB, and therefore misses many convenience features. Instead, these convenience methods have been split out into a layer written in PHP, the MongoDB Library. Using this library should be your preferred way of interacting with MongoDB.
该库需要使用PHP的软件包管理器 Composer 进行安装.另请参见获取Composer:在Linux/OSX上安装
The library needs to be installed with Composer, a package manager for PHP. See also Get Composer: Installation on Linux/OSX
例如:
composer require "mongodb/mongodb=^1.0.0"
安装完成后，您可以尝试使用以下方式进行连接:
Once you have it installed, you can try connecting using:
<?php
require 'vendor/autoload.php';
$collection = (new MongoDB\Client("mongodb://127.0.0.1:27017"))->dbname->coll;
?>
