为了应对当前HTML格式和js脚本对老人机的不友好，我们需要处理一下某些小说网站，让它回到十几年前的样子，剔除大量CSS和JS，精简HTML标签，这样就能够让老人机快速、友好地看小说了。
目前下面的脚本就能实现了，可以为老人机提供简单地浏览和必备的搜索功能，并且支持缓存。
简单说明
_remoteurl_ ：填写链接
_band_word_ ：删除关键词
_band_href_ ：删除URL包含该值的链接
_band_ele_ ：把某些没有替换掉的元素删除掉，这个设置的存在是由一个正则匹配引起的，一般不要修改。
关于缓存：在源码内搜索 $keeptime 即可找到相关代码。
快速配置 1. 基本配置
define处修改remoteurl和其他配置，注意看注释，别乱来。
2. 搜索配置
找到 if ($_GET['search']) : 这一行，下面有
$html = c_get('https://search2.booktxt.net/s.php', 'post', 't=1&keyword='.urlencode(_iconv($_GET['search'], 'GBK')));
这样一行，修改c_get的参数即可。
第一个参数是url，第二个是方式(post/get)，第三个是传输过去的请求字符串，可能要用到转码功能，具体看对面页面的编码，用 _iconv (脚本自构的函数) 转换。具体写什么需要手动抓取网站信息手动填好。
例子： # define_remoteurl:
define('_remoteurl_', 'https://www.biqutxt.com/');
# $_GET['search']后边:
$html = c_get('https://www.biqutxt.com/modules/article/search.php', 'post', 'searchtype=articlename&action=login&searchkey='.urlencode(_iconv($_GET['search'], 'GBK')));
若出现乱码，则可能为转码问题，也可能为原网页的问题，需排查，可以把URL上面的page参数进行urldecode+base64decode即得到源URL。
