excel导出

该项目的GitHub地址是：github.com/Maatwebsite…

本文我们将在thinkphp中使用Thinkphp Excel简单实现Excel文件的导入和导出。

安装excel 从GitHub上下载PHPExcel类库 地址：github.com/PHPOffice/P…

解压后将Classes文件夹移动到ThinkPHP的extend目录，并将其重命名为phpexcel

代码实现

        public function excel(){
         // 引入类库
         include "../extend/phpexcel/PHPExcel.php";

         // 文件名和文件类型
         $fileName = "student";
         $fileType = "xlsx";
 
         // 模拟获取数据
         $data = News::select();
        // dump($data);die();
         $obj = new \PHPExcel();
 
         // 以下内容是excel文件的信息描述信息
         $obj->getProperties()->setCreator(''); //设置创建者
