ThinkPHP上傳並讀取csv文件數據

       $path = 'Public/sxwx/account_csv/';
       $upload = new \Think\Upload();// 實例化上傳類
       $upload->maxSize = 3145728 ;// 設置附件上傳大小

       $upload ->saveName = 'account_'.time();

       // 上傳文件
       $info = $upload->uploadOne($_FILES['account']);
       if(!$info) {// 上傳錯誤提示錯誤信息
           $this -> backMsg('0', '無效的文件');
       }
           //上傳成功 獲取上傳文件信息
        $name = $info['savename'];
