php MongoDB 操作示例

• 查询

  $filter = [
              '_id' => new MongoDB\BSON\ObjectId("$id"),
              'creater_id' => $user['user_id'],
              'delete_flag' => 'N',
          ];  // 查询条件
  
          $options = [
              'projection' => ['_id' => 1, 'id' => 1, 'title' => 1, 'status' => 1, 'delete_flag' => 1],
                              'limit' => $page_size,                                                       // limit
                              'skip' => (int)(($page_index - 1) * $page_size),               // 跳过
                              'sort' => ['create_time' => -1]                                            // 排序
          ];  // 操作项
  
          $doc = $this->mongo_db->findOne('table', $filter, $options);
          return !empty($doc) ? $doc->getArrayCopy() : [];
          // getArrayCopy() 将查询结果转为数组

• 更新

  $filter = [
          '_id' => new MongoDB\BSON\ObjectId("$id")  // 匹配条件
      ];
  
      $options = [
          '$set' => ['delete_flag' => 'Y']   // 设置要更新的字段值
      ];
  
      $doc = $this->mongo_db->updateOne('table', $filter, $options);
      $modified_count = $doc->getModifiedCount();
      if ($modified_count == 1)
      {
          return true;
      }
  
              // getModifiedCount() 获取被影响行数
              // getMatchedCount() 获取查询结果匹配数

• 聚簇
