phpExcel实现excel文件导出

1. 下载PHPExcel的SDK，下载地址为：https://github.com/PHPOffice/PHPExcel，将下载的文件解压后，在自己项目common目录下新建phpexcel目录，将Classes目录下的文件拷贝到phpexcel下。

2. 导出excel文件，代码如下

   // 引入PHPExcel文件include_once ROOT_PATH.'/app/common/phpexcel/PHPExcel.php';//实例化并配置PHPExcel$objPHPExcel = new \PHPExcel();$objPHPExcel->getProperties()->setCreator("Maarten Balliauw")->setLastModifiedBy("Maarten Balliauw")->setTitle("Office 2007 XLSX Test Document")->setSubject("Office 2007 XLSX Test Document")->setDescription("Test document for Office 2007 XLSX, generated using PHP classes.")->setKeywords("office 2007 openxml php")->setCategory("Test result file");//为表格添加表头$objPHPExcel->setActiveSheetIndex(0)//Excel的第A列，uid是你查出数组的键值，下面以此类推->setCellValue('A1',"活动ID")->setCellValue('B1',"客户名称")->setCellValue('C1',"交易号")->setCellValue('D1',"金额")->setCellValue('E1',"支付时间")->setCellValue('F1',"活动名称")->setCellValue('G1',"活动时间");/*以下就是对处理Excel里的数据， 横着取数据，主要是这一步，其他基本都不要改*/foreach($data as $k => $v){$num=$k+2;$objPHPExcel->setActiveSheetIndex(0)->setCellValue('A'.$num, $v->liveId)->setCellValue('B'.$num, $v->nickName)->setCellValue('C'.$num, "\t" . $v->out_trade_no . "\t")->setCellValue('D'.$num, round($v->payedmoney/100,2))->setCellValue('E'.$num, $v->payedTime)->setCellValue('F'.$num, $v->locationTime);}// 为表格设置表格名称$objPHPExcel->getActiveSheet()->setTitle('User');// 设置表格大小自适应$objPHPExcel->getActiveSheet()->getColumnDimension('A')->setAutoSize(true);$objPHPExcel->getActiveSheet()->getColumnDimension('B')->setAutoSize(true);$objPHPExcel->getActiveSheet()->getColumnDimension('C')->setAutoSize(true);$objPHPExcel->getActiveSheet()->getColumnDimension('D')->setAutoSize(true);$objPHPExcel->getActiveSheet()->getColumnDimension('E')->setAutoSize(true);$objPHPExcel->getActiveSheet()->getColumnDimension('F')->setAutoSize(true);$objPHPExcel->setActiveSheetIndex(0);//通过浏览器下载表格header('Content-Type: application/vnd.ms-excel');header('Content-Disposition: attachment;filename="'.$name.'.xls"');header('Cache-Control: max-age=0');header('Cache-Control: max-age=1');// If you're serving to IE over SSL, then the following may be neededheader ('Expires: Mon, 26 Jul 1997 05:00:00 GMT'); // Date in the pastheader ('Last-Modified: '.gmdate('D, d M Y H:i:s').'
