购买记录和评论的用户名使用如下方式缩写：j***y

找到includes/lib_insert.php

如下代码：

$bought_notes[$key]['add_time'] = local_date("Y-m-d G:i:s", $val['add_time']);

在其下面添加这个：

$bought_notes[$key]['user_name'] = mb_substr($val['user_name'], 0, 1, 'utf-8').'***'. mb_substr($val['user_name'], -1, 1, 'utf-8');

这是修改的购买记录！

找到includes/lib_main.php

$arr[$row['comment_id']]['username'] = $row['user_name'];

将其替换为：

$arr[$row['comment_id']]['username'] = mb_substr($row['user_name'], 0, 1, 'utf-8').'***'. mb_substr($row['user_name'], -1, 1, 'utf-8');
