在Windows上安装phpMongo驱动程序

I want to run mongodb from PHP 5.6. I have downloaded it from https://github.com/mongodb/mongo-php-library. I run the command composer require "mongodb/mongodb=^1.0.0" and what about the zip file? Is there any easy method to install it?

I run this code

<?php
 require 'vendor/autoload.php';
 $connection = new MongoDB();

?>

and getting error:

Fatal error: Class 'MongoDB' not found in C:\wamp64\www\

new MongoDB\Client("mongodb://localhost:27017"); 

works fine but for saving the document $collection->insert($document); gives the error insert method is not found

If the files are in the vendor map the installation via composer went probably well. I think the problem now is that you want to create an instance of a class that doesn't exist. Isn't MongoDB the namespace and not the class?

From the documentation of MongoDB:

$database = (new MongoDB\Client)->selectDatabase('db_name');

See the documentation on namespaces: http://php.net/manual/en/language.namespaces.php

-edit-

For inserting you should use insertOne() according to the documentation: http://mongodb.github.io/mongo-php-library/classes/collection/#insertone

function insertOne($document, array $options = []): MongoDB\InsertOneResult
