THINKPHP 導入xlxs文件

1、需要下載PHPExcel文件

 public function upload()
    {
        header("Content-Type:text/html;charset=utf-8");
        $upload = new \Think\Upload();// 實例化上傳類
        $upload->maxSize   =     3145728 ;// 設置附件上傳大小
        $upload->exts      =     array('xls', 'xlsx');// 設置附件上傳類
        $upload->savePath  =      '/'; // 設置附件上傳目錄
        // 上傳文件
    
        $info   =   $upload->uploadOne($_FILES['mypic']);
        $filename = './Uploads'.$info['savepath'].$info['savename'];
        $exts = $info['ext'];
        if ($exts != "xls" && $exts != "xlsx") {
            //echo '文件格式不對！';
            //exit;
        }
        
        if(!$info) {// 上傳錯誤提示錯誤信息
            die(json_encode(array("result"=>0)));
//             $this->error($upload->getError());
        }else{// 上傳成功調用導入的方法
            $this->import($filename, $exts);
        }
    }
    //時間轉換類
    public function GetData($val){
        $n = intval(($val - 25569) * 3600 * 24); //轉換成1970年以來的秒數
        $gregorian=gmdate('Y-m-d H:i:s', $n);//格式化時間
        return $gregorian;
    }
    
    //導入數據方法
    protected function import($filename, $exts)
    {
        //導入PHPExcel類庫，因爲PHPExcel沒有用命名空間，只能inport導入
        import("Org.Util.PHPExcel");
        //創建PHPExcel對象，注意，不能少了\
        $PHPExcel=new \PHPExcel();
        //如果excel文件後綴名爲.xls，導入這個類
    
        if($exts == 'xls'){
            import("Org.Util.PHPExcel.Reader.Excel5");

        //載入文件
        $PHPExcel=$PHPReader->load($filename);
    
        //獲取表中的第一個工作表，如果要獲取第二個，把0改爲1，依次類推
        $currentSheet=$PHPExcel->getSheet(0);
        //獲取總列數
        $allColumn=$currentSheet->getHighestColumn();
        //獲取總行數
        $allRow=$currentSheet->getHighestRow();
        //循環獲取表中的數據，$currentRow表示當前行，從哪行開始讀取數據，索引值從0開始
        for($currentRow=2;$currentRow<=$allRow;$currentRow++){
            //從哪列開始，A表示第一列
            for($currentColumn='A';$currentColumn<=$allColumn;$currentColumn++){
                //數據座標
                $address=$currentColumn.$currentRow;
                //讀取到的數據，保存到數組$arr中
