项目地址https://github.com/mongodb/mongo-php-library因为项目是国外友人贡献的。所以没有可以看的很明白的文档。这里整理了一些常用的方法。
获取实例$uri = mongodb://username:password@host/database;$client = new \mongodb\client($uri);
获取集合$collection = $client->selectcollection('test','test');
获取一条数据$data = $collection->findone(['id'=>1]);
获取多条数据$where = ['type'=>1];$options = array( 'projection' => array('id' => 1, 'age' => 1, 'name' => -1), // 指定返回哪些字段 1 表示返回 -1 表示不返回 'sort' => array('id' => -1), // 指定排序字段 'limit' => 10, // 指定返回的条数 'skip' => 0, // 指定起始位置);$data = $collection->find($where,$options)->toarray();var_dump($data);
去重$filename = 'name';$where = ['id' => ['$lt' => 100]]$ret = $this->collection->distinct($filename,$where);
插入一条数据$data = array( 'id' => 2, 'age' => 20, 'name' => '张三');$ret = $collection->insertone($data);$id=$ret->getinsertedid();
批量插入$data = array( ['id' => 1, 'age' => 21, 'name' => '1xiaoli'], ['id' => 2, 'age' => 22, 'name' => '2xiaoli'], ['id' => 3, 'age' => 23, 'name' => '3xiaoli'], ['id' => 4, 'age' => 26, 'name' => '4xiaoli'], ['id' => 5, 'age' => 24, 'name' => '5xiaoli'], ['id' => 6, 'age' => 25, 'name' => '6xiaoli'],);$ret = $collection->insertmany($data);# 返回插入idvar_dump($ret->getinsertedids());
更新一条$ret = $collection->updateone(array('id' => 2), array('$set' => array('age' => 56)));
更新多条$ret = $collection->updatemany(array('id' => ['$gt' => 1]), array('$set' => array('age' => 56, 'name' => 'x')));
删除一条$ret = $collection->deleteone(array('id' => 2));
删除多条$collection->deletemany(array('id' => array('$in' => array(1, 2))));
聚合$ops = [ [ '$match' =>['type'=>['$in'=>[2,4]]] ], [ '$sort' => ['list.create_time' => -1] //sort顺序不能变，否则会造成排序混乱，注意先排序再分页 ], [ '$skip' => 0 ], [ '$limit' => 20000 ],];$data = $collection->aggregate($ops);foreach ($data as $document){ var_dump($document);}
