php7中使用mongodb的驱动

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 = array() ] ) 执行数据库命令
$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() ] )
  $filter = ['x' => ['$gt' => 0]];//查询条件
$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);
}
4、MongoDB\Driver\Manager::executeReadCommand ( string $db , MongoDB\Driver\Command $command [, array$options = array() ] )执行读取数据的数据库命令
和MongoDB\Driver\Manager::executeCommand用法一样
5、MongoDB\Driver\Manager::executeReadWriteCommand( string $db , MongoDB\Driver\Command $command [, array$options = array() ] )执行读取写入文件的数据库命令
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
7、MongoDB\Driver\Manager::getReadConcern ( void ) //Return the ReadConcern for the Manager
$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]);

    $num = $bulk->count();

  3、MongoDB\Driver\BulkWrite::insert(array|object $document)

  4、MongoDB\Driver\BulkWrite::update(array|object $filter , array|object $newObj [, array $updateOptions ] )

  5、MongoDB\Driver\BulkWrite::delete(array|object $filter [, array $deleteOptions ])

     'query' => $query // 条件

  $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);

  }

五、MongoDB\Driver\WriteConcern

  1、MongoDB\Driver\WriteConcern(string|integer $w [, int $wtimeout [, bool $journal ]])创造一个新的WriteConcern

    $w 是0,1,或者大于1的整数,MongoDB\Driver\WriteConcern::MAJORITY(常量)

六、MongoDB\Driver\ReadPreference

  1、MongoDB\Driver\ReadPreference(string|integer $mode [, array $tagSets = NULL [, array$options = array() ]] )创造一个新的ReadPrefenerce

    $mode :

    MongoDB\Driver\ReadPreference::RP_PRIMARY or "primary"

    MongoDB\Driver\ReadPreference::RP_PRIMARY_PREFERRED or "primaryPreferred"

    MongoDB\Driver\ReadPreference::RP_SECONDARY or "secondary"

    MongoDB\Driver\ReadPreference::RP_SECONDARY_PREFERRED or "secondaryPreferred"

    MongoDB\Driver\ReadPreference::RP_NEAREST or "nearest"

  4、MongoDB\Driver\ReadPreference::getMode( void )

  5、MongoDB\Driver\ReadPreference::getTagSets( void )

七、MongoDB\Driver\ReadConcern

  1、MongoDB\Driver\ReadConcern([ string $level ] )创造一个新的ReadConcern

    $level https://docs.mongodb.com/manual/reference/read-concern/#read-concern-levels

  2、MongoDB\Driver\ReadConcern ::bsonSerialize ( void )//返回用于序列化的对象

  3、MongoDB\Driver\ReadConcern ::getLevel( void )

  4、MongoDB\Driver\ReadConcern ::isDefault ( void )//检查是否为默认读取关系

八、MongoDB\Driver\Cursor

  1、MongoDB\Driver\Cursor()创建一个新光标(未使用)

  2、MongoDB\Driver\Cursor::getId( void )//返回此游标的id

  3、MongoDB\Driver\Cursor::getServer( void )//返回与此游标关联的服务器

  4、MongoDB\Driver\Cursor::isDead( void )//检查游标是否可能具有额外结果
