phpexcel使用说明5----ThinkPHP+PHPExcel[导入][导出]实现方法

转自：http://www.thinkphp.cn/code/403.html
实现步骤：

注意：phpexcel必须是1.78版本的，不能用1.8以上的
一：去官网http://phpexcel.codeplex.com/下载最新PHPExcel放到Vendor下，注意位置：ThinkPHPExtendVendorPHPExcelPHPExcel.php。
二：在CommonAction.class.php中添加以下两个函数：

使用方法
导入：

1. function impUser(){
2.      if(isset($_FILES["import"]) && ($_FILES["import"]["error"] == 0)){
3.         $result = $this->importExecl($_FILES["import"]["tmp_name"]);
4.         if($result["error"] == 1){          
5.           $execl_data = $result["data"][0]["Content"];
6.                   foreach($execl_data as $k=>$v){
7.                       ..这里写你的业务代码..
8.                   }
9.          }
10.       }
11. }

复制代码

导出：

1. function expUser(){//导出Excel
2.         $xlsName  = "User";
3.         $xlsCell  = array(
4.             array('id','账号序列'),
5.             array('account','登录账户'),
