yii phpexcel自己主动生成文件保存到server上

近期再整一个报表任务，每天必须把表导出来按excel格式发送邮件给管理员，利用phpexcel把表保存到server上。然后再通过phpmailer发送就ok.

        ob_end_clean();  
        ob_start();
        $objectPHPExcel = new PHPExcel();
        $objectPHPExcel->setActiveSheetIndex(0);

            $objectPHPExcel->setActiveSheetIndex(0)->setCellValue("A$i",$resource->source_name);
            $objectPHPExcel->setActiveSheetIndex(0)->setCellValue("B$i", $one);
            $objectPHPExcel->setActiveSheetIndex(0)->setCellValue("C$i", $two);
            $objectPHPExcel->setActiveSheetIndex(0)->setCellValue("D$i", $three);
            $objectPHPExcel->setActiveSheetIndex(0)->setCellValue("E$i", $price);
            $objectPHPExcel->setActiveSheetIndex(0)->setCellValue("F$i", $goods_price);
            $objectPHPExcel->setActiveSheetIndex(0)->setCellValue("G$i", $product);
            $objectPHPExcel->setActiveSheetIndex(0)->setCellValue("H$i", $count);

        $filename   = "c.xls";
        $objWriter  = PHPExcel_IOFactory::createWriter($objectPHPExcel, 'Excel5');
        $objWriter->save($filename);

注意再生成的时候打开生成的excel,再次生成就会出现fopen权限报错。帮助到的留言，哈哈
