[转]ThinkPHP+PHPExcel[导入][导出]实现方法

实现步骤:
一:去官网http://phpexcel.codeplex.com/下载最新PHPExcel放到Vendor下,注意位置:ThinkPHP\Extend\Vendor\PHPExcel\PHPExcel.php。
二:在CommonAction.class.php中添加以下两个函数:

使用方法
导入:

  1. function impUser(){
         if(isset($_FILES["import"]) && ($_FILES["import"]["error"] == 0)){
            $result = $this->importExecl($_FILES["import"]["tmp_name"]);
            if($result["error"] == 1){          
              $execl_data = $result["data"][0]["Content"];
                      foreach($execl_data as $k=>$v){
                          ..这里写你的业务代码..
                      }
             }
          }
    }


导出:

  1. function expUser(){//导出Excel
            $xlsName  = "User";
            $xlsCell  = array(
                array('id','账号序列'),
                array('account','登录账户'),
                array('nickname','账户昵称')
            );
            $xlsModel = M('Post');
            $xlsData  = $xlsModel->Field('id,account,nickname')->select();
            $this->exportExcel($xlsName,$xlsCell,$xlsData);
        }
