一、MongoDB\Driver\Manager
1、MongoDB\Driver\Manager ([ string $uri
= “mongodb://127.0.0.1/ [, array $uriOptions
= array() [, array$driverOptions
= array() ]]] )构造方法,连接mongodb数据库
$conn = new MongoDB\Driver\Manager([ string $uri
= “mongodb://127.0.0.1:27017/ [, array $uriOptions
= array() [, array$driverOptions
= array() ]]] );
参数说明:
uri: mongodb://[username:password@]host1[:port1][,host2[:port2],…[,hostN[:portN]]][/[database][?options]]
uriOptions: 见http://php.net/manual/zh/mongodb-driver-manager.construct.php
driverOptions:见http://php.net/manual/zh/mongodb-driver-manager.construct.php
2、MongoDB\Driver\Manager::executeBulkWrite( string$namespace
, MongoDB\Driver\BulkWrite$bulk
[, array$options
= array() ] ) 执行bulk的一些操作,包括混合操作
$bulk = new MongoDB\Driver\BulkWrite();
$bulk->delete([]);
$bulk->insert(['x' => 7, 'name'=>'菜鸟教程', 'url' => 'http://www.runoob.com']);
$bulk->insert(['x' => 2, 'name'=>'Google', 'url' => 'http://www.google.com']);
$bulk->insert(['x' => 3, 'name'=>'taobao', 'url' => 'http://www.taobao.com']);
$bulk->update(['x'=>2],['$set'=>['name'=>'谷歌']]);
$bulk->insert(['x' => 6, 'title'=>'淘宝', 'url' => 'http://www.taobao.com']);
$conn->executeBulkWrite('test.runboo',$bulk);
说明:test.runboo代表:数据库.集合名
3、MongoDB\Driver\Manager::executeCommand( string$db
, MongoDB\Driver\Command$command
[, array$options

$query = ['name' => 'taobao']; // 查询条件
$cmd = new MongoDB\Driver\Command([
'distinct' => 'runboo', // 集合名称
'key' => 'url', // 需要显示的字段
'query' => $query // 条件
]);
$cursor = $conn->executeCommand('test', $cmd); // 数据库名称和命令
$scents = $cursor->toArray(); // 转换成数组
var_dump($scents); 4、MongoDB\Driver\Manager::executeQuery ( string$namespace
, MongoDB\Driver\Query$query
[, array$options
= array() ] )

$options = [
'projection' => ['_id' => 0],
];
$query = new MongoDB\Driver\Query($filter,$options);//查询请求
$rows = $conn->executeQuery('test.sites', $query); // 执行查询
foreach($rows as $r){
var_dump($r);
}

和MongoDB\Driver\Manager::executeCommand用法一样
6、MongoDB\Driver\Manager::executeWriteCommand ( string$db
, MongoDB\Driver\Command$command
[, array$options
= array() ] )执行写入文件的数据库命令
和MongoDB\Driver\Manager::executeCommand用法一样

$cursor = $conn->getReadPreference();
var_dump($cursor);
//object(MongoDB\Driver\ReadConcern)#2 (0) { }
8、MongoDB\Driver\Manager::getReadPreference ( void ) //Return the ReadPreference for the Manager
$cursor = $conn->getReadPreference();
var_dump($cursor);
//object(MongoDB\Driver\ReadPreference)#2 (1) { ["mode"]=> string(7) "primary" }
9、MongoDB\Driver\Manager::getServers ( void )//返回该管理器连接的服务器
$conn->getServers();
10、MongoDB\Driver\Manager::getWriteConcern ( void )//Return the WriteConcern for the Manager
$conn->getWriteConcern();
11、MongoDB\Driver\Manager::selectServer( MongoDB\Driver\ReadPreference $readPreference
)//选择匹配读取首选项的服务器
12、MongoDB\Driver\Manager::startSession([ array $options
] )//启动一个新客户端会话,以便与此客户端一起使用
二、MongoDB\Driver\BulkWrite
1、MongoDB\Driver\BulkWrite 混合写入操作(即插入、更新和删除)将是 组装成类型化写入命令,以便依次发送到服务器
$bulk = new MongoDB\Driver\BulkWrite([‘ordered’ => true]);
$bulk->insert([‘_id’ => 1, ‘x’ => 1]);
$bulk->insert([‘_id’ => 2, ‘x’ => 2]);
$bulk->update([‘x’ => 2], [‘$set’ => [‘x’ => 1]]);
$bulk->insert([‘_id’ => 3, ‘x’ => 3]);
$bulk->delete([‘x’ => 1]);
$conn->executeBulkWrite(‘test.runboo’,$bulk);
说明:ordered有true和false,默认是false
2、MongoDB\Driver\BulkWrite::count() //计数-计算批量写入操作数
$bulk = new MongoDB\Driver\BulkWrite([‘ordered’ => true]);
$bulk->insert([‘_id’ => 1, ‘x’ => 1]);
$bulk->insert([‘_id’ => 2, ‘x’ => 2]);
$bulk->update([‘x’ => 2], [‘$set’ => [‘x’ => 1]]);
$bulk->insert([‘_id’ => 3, ‘x’ => 3]);
$bulk->delete([‘x’ => 1]);

$rows = $conn->executeQuery(‘test.sites’, $query); // 执行查询
foreach($rows as $r){
var_dump($r);
}

MongoDB\Driver\ReadPreference::RP_PRIMARY_PREFERRED or “primaryPreferred”
MongoDB\Driver\ReadPreference::RP_SECONDARY or “secondary”
MongoDB\Driver\ReadPreference::RP_SECONDARY_PREFERRED or “secondaryPreferred”
