php使用phpexcel插件实现导入导入道出功能
首先下载phpexcel插件下载结果如下:

   $array=array_merge($array);             
   $data=array_chunk($array,2000);
   $count_data=count($data);

    $data_list = M('data_list');
    
    $i=0;
    //插入数据到数据库
    while ($i<$count_data) {
       $users=$data_list->addAll($data[$i]);
       $i++;
    }
    unlink($path);
   return 1;

注意:导入时文件路径要是真实路径临时路径会出问题
