数据插入：

$manager = new MongoDB\Driver\Manager('mongodb://localhost:27017');
$bulk = new MongoDB\Driver\BulkWrite;
$bulk->insert(['name' => 'JetWu5', 'age' => 26]);
$bulk->insert(['name' => 'JetWu6', 'age' => 26]);
$writeConcern = new MongoDB\Driver\WriteConcern(MongoDB\Driver\WriteConcern::MAJORITY, 1000);//可选，修改确认
$res = $manager->executeBulkWrite('wjt.friend', $bulk, $writeConcern);
echo '<pre>';
print_r($res);

数据查询：

$manager = new MongoDB\Driver\Manager('mongodb://localhost:27017');
$query = new MongoDB\Driver\Query(['age' => 24], ['sort' => ['age' => 1]]);
$cursor = $manager->executeQuery('wjt.friend', $query);
$data = [];
foreach($cursor as $doc) {
  $data[] = $doc;
}
echo '<pre>';
print_r($data);

数据修改：

 

$manager = new MongoDB\Driver\Manager('mongodb://localhost:27017');
$bulk = new MongoDB\Driver\BulkWrite;
$bulk->update(
  ['name' => 'JetWu5'],
  ['$set' => ['age' => 30, 'promise' => 'always smile!']]
);
$writeConcern = new MongoDB\Driver\WriteConcern(MongoDB\Driver\WriteConcern::MAJORITY, 1000);//可选，修改确认
$res = $manager->executeBulkWrite('wjt.friend', $bulk, $writeConcern);
echo '<pre>';
print_r($res);

数据删除：

 

$manager = new MongoDB\Driver\Manager('mongodb://localhost:27017');
$bulk = new MongoDB\Driver\BulkWrite;
$bulk->delete(['name' => 'JetWu3']);
$bulk->delete(['name' => 'JetWu4']);
$writeConcern = new MongoDB\Driver\WriteConcern(MongoDB\Driver\WriteConcern::MAJORITY, 1000);//可选，修改确认
$res = $manager->executeBulkWrite('wjt.friend', $bulk, $writeConcern);
echo '<pre>';
