導出excel後wps能用 excel打開亂碼，是因為導出的類使用方式問題

把$objWriter = new \PHPExcel_Writer_Excel2007($this->_obj);

換成$objWriter = \PHPExcel_IOFactory::createWriter($this->_obj, ‘Excel5‘); 就能解決問題

 public function output($file_name){
        //直接輸出到瀏覽器
        header("Pragma: public");
        header("Expires: 0");
        
 
header("Cache-Control:must-revalidate, post-check=0, pre-check=0");
        header("Content-Type:application/force-download");
        header("Content-Type:application/ms-execl");
        header("Content-Type:application/octet-stream");
        header("Content-Type:application/download");
        header(‘Content-Disposition:attachment;filename="‘.$file_name
 
);
        header("Content-Transfer-Encoding:binary");
        
//        $objWriter =  new \PHPExcel_Writer_Excel2007($this->_obj);  直接使用會導致wps能用，excel打開報錯，產生亂碼
        $objWriter = \PHPExcel_IOFactory::createWriter($this->_obj, ‘Excel5‘); //下面的用法就能解決
        $objWriter->save(‘php://output‘);
    }
