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：

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..

                  }

         }

      }

 }

复制代码

导出：

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);

    }
