Answer 1

在设置mongodb之前，我遇到了相同的错误，将以下链接添加到'vendor / autoload.php'。在许多情况下，您需要检查主机。我的代码如下所示后，它开始工作：

  $DB_CONNECTION_STRING="mongodb://YourCredentials";
  require '../../vendor/autoload.php';
  $manager = new MongoDB\Driver\Manager( $DB_CONNECTION_STRING );

然后，如果您使用MongoDB驱动程序的现代版本MongoDB \ Driver \ Manager，您将具有以下外观：

创建集合中的文档：

$bulkWrite = new MongoDB\Driver\BulkWrite;
$doc = ['name' => 'John', age => 33, profession => 'Guess what?'];
$bulkWrite->insert($doc);
$manager->executeBulkWrite('db.MyCollection', $bulkWrite);

阅读文档集中的文档的名称，并带有限制：

$filter = ['name' => 'John'];
$options = ['limit' => 2];
$query = new MongoDB\Driver\Query($filter, $options);
$manager->executeQuery('db.MyCollection', $query);

由MongoDb _id读取集合中的文档，但有以下限制：

$filter = ['_id' => new MongoDB\BSON\ObjectID( '5bdf54e6d722dc000f0aa6c2' )];
$options = ['limit' => 2];
$query = new MongoDB\Driver\Query($filter, $options);
$manager->executeQuery('db.MyCollection', $query);    

集合中的

更新文档：（（有关选项upsert和multi here的更多信息）

$bulkWrite = new MongoDB\Driver\BulkWrite;
$filter = ['name' => 'John'];
$update = ['$set' => ['name' => 'Smith', age: 35, profession => 'Guess what?']];
$options = ['multi' => false, 'upsert' => false];
$bulkWrite->update($filter, $update, $options);
$manager->executeBulkWrite('db.MyCollection', $bulkWrite);    

集合中的

删除文档-删除：

$bulkWrite = new MongoDB\Driver\BulkWrite;
$filter = ['name' => 'John', age => 35];
$options = ['limit' => 1];
$bulkWrite->delete($filter, $options);
$manager->executeBulkWrite('db.MyCollection', $bulkWrite);
