    一:插入数据

    例:向默认的test数据库的wj表中插入数据

    $manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");  

    // 插入数据
    $bulk = new MongoDB\Driver\BulkWrite;
    $bulk->insert(['id' => 1, 'name'=>'测试', 'url' => 'http://www.百度.com']);
    $manager->executeBulkWrite('test.wj', $bulk);

    2:查询数据

    查询test数据库的wj表中name值不为测试的数据

    $manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");  
    $filter = ['name' => '测试'];
    $options = [
        'projection' => ['_id' => 0],
        'sort' => ['name' => -1],
    ];
    $query = new MongoDB\Driver\Query($filter, $options);
    $cursor = $manager->executeQuery('test.wj', $query);
    foreach ($cursor as $document) {
        print_r($document);
    }

    3:更新数据

    将test数据库中的wj表中id为1的数据中name字段变为测试1234,

    $bulk = new MongoDB\Driver\BulkWrite;
    $bulk->update(
        ['id' => 1],
        ['$set' => ['name' => '测试1234']],
        ['multi' => false, 'upsert' => false]  #multi表示只更新一条数据,upsert表示如果不存在update的记录,不进行插入操作
    );
    $manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");  
    $writeConcern = new MongoDB\Driver\WriteConcern(MongoDB\Driver\WriteConcern::MAJORITY, 1000);
    $result = $manager->executeBulkWrite('test.wj', $bulk, $writeConcern);

    4:删除数据

    $bulk = new MongoDB\Driver\BulkWrite;
    $bulk->delete(['id' => 1], ['limit' => 1]);   // limit 为 1 时,删除第一条匹配数据
    $bulk->delete(['id' => 2], ['limit' => 0]);   // limit 为 0 时,删除所有匹配数据
    $manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");  
    $writeConcern = new MongoDB\Driver\WriteConcern(MongoDB\Driver\WriteConcern::MAJORITY, 1000);
    $result = $manager->executeBulkWrite('test.wj', $bulk, $writeConcern);
