使用phpexcel的示例 [ 2.0 版本 ]

public function actionDownexcel()
{
    //要使用的数据
    $repair_infos = ConDbRepair::find()->asArray()->all();
    //实例化
    $objPHPExcel = new \PHPExcel();
    $objWriter = new \PHPExcel_Writer_Excel5($objPHPExcel);
    //这里是显示的标题字段 也就是你数据库的字段名称
    $objPHPExcel->getActiveSheet()->setCellValue('A1',  '日期');//这里是设置A1单元格的内容
    $objPHPExcel->getActiveSheet()->setCellValue('B1',  '维修名称');////这里是设置B1单元格的内容
    $objPHPExcel->getActiveSheet()->setCellValue('C1',  '维修类型');////这里是设置B1单元格的内容
    $objPHPExcel->getActiveSheet()->setCellValue('D1',  '消耗库存');////这里是设置B1单元格的内容
    $objPHPExcel->getActiveSheet()->setCellValue('E1',  '维修费用');////这里是设置B1单元格的内容
    $objPHPExcel->getActiveSheet()->setCellValue('F1',  '成本');////这里是设置B1单元格的内容
    $objPHPExcel->getActiveSheet()->setCellValue('G1',  '毛利');////这里是设置B1单元格的内容
    //这里是每条数据的内容了
    foreach ($repair_infos as $key => $value) {
        $i=$key+2;//表格是从1开始的
        $objPHPExcel->getActiveSheet()->setCellValue('A'.$i,  $value['update_time']);
        $objPHPExcel->getActiveSheet()->setCellValue('B'.$i,  $value['repair_name']);
        $objPHPExcel->getActiveSheet()->setCellValue('C'.$i,  $value['repair_name']);
        $objPHPExcel->getActiveSheet()->setCellValue('D'.$i,  $value['repair_price']);
        $objPHPExcel->getActiveSheet()->setCellValue('E'.$i, $value['repair_name']);
        $objPHPExcel->getActiveSheet()->setCellValue('F'.$i,  $value['repair_price']);
        $objPHPExcel->getActiveSheet()->setCellValue('G'.$i,   $value['repair_price']);
    }
    //接下来当然是下载这个表格了，在浏览器输出就好了
    $file_name = date('YmdHis');
