我不认为您想直接致电经理。更新的MongoDB扩展，取代了内置的PHP Mongo DB客户端;您需要满足以下要求才能使代码生效。下面的代码示例假设如下：

使用composer autoloader加载。
您可以从此处获得新的MongoDB驱动程序扩展程序：http://php.net/manual/en/set.mongodb.php
您从这里使用作曲家MongoDB客户端库：http://php.net/manual/en/mongodb.tutorial.library.php
PHP＆gt; = 5.6

use MongoDB\Client as MongoDbClient;
// When auth is turned on, then pass in these as the second parameters to the client.
$options = [
    'password' => '123456',
    'username' => 'superUser',
];

try {
    $mongoDbClient = new MongoDbClient('mongodb://localhost:27017');
} catch (Exception $error) {
    echo $error->getMessage(); die(1);
}

// This will get or make (in case it does not exist) the inventory database
// and a collection beers in the Mongo DV server.
$collection = $mongoDbClient->inventory->beers;

$collection->insertOne( [ 'name' => 'Hinterland', 'brewery' => 'BrewDog' ] );

$result = $collection->find( [ 'name' => 'Hinterland', 'brewery' => 'BrewDog' ] );

foreach ($result as $entry) {
    echo $entry['_id'], ': ', $entry['name'], "\n";
}
