操作mongodb -- mongodb扩展

前置条件：
需要安装 mongodb 扩展

使用：

 <?php
 // 使用命名空间
 use \MongoDB\Driver\Manager;
 use \MongoDB\Driver\BulkWrite;
 use \MongoDB\Driver\Query;
 // 连接 mongodb（副本集）
 $manager = new Manager("mongodb://10.0.0.11:27200,10.0.0.12:27200,10.0.0.13:27200");
 $bulk = new BulkWrite();
 // 新增
 $bulk->insert(["name" => "lee", "age" => 30]);
 $bulk->insert(["name" => "zhangsan", "age" => 18]);
 $manager->executeBulkWrite("test.coTest", $bulk);
 // 删除
 $bulk->delete(["name" => "zhangsan"], ["limit" => 1]);  // 删除一条记录
 $bulk->delete(["name" => "zhangsan"], ["limit" => 0]);  // 删除全部匹配的记录
 $manager->executeBulkWrite("test.coTest", $bulk);
 // 更新
 $bulk->update(
     ["name" => "zhangsan"],
     ["\$set" => ["age" => 19]],
     ["multi" => false, "upsert" => false]
 );
 $manager->executeBulkWrite("test.coTest", $bulk);
 // 查询
 $query = new Query(["age" => ["\$lt" => 20]], ["projection" => ["_id" => 0, "name" => 1], "sort" => ["name" => -1]]);
 $cursor = $manager->executeQuery('test.coTest', $query);
 foreach ($cursor as $document) {
     print_r($document);
 }
