后端开发-php教程
本文所述留言板程序使用了无限级分类的原理，可以实现无限级留言与回复。留言列表gclist保留了留言层次空格，使留言–回复层次分明。分享给大家供大家参考。具体分析如下：
电脑应用源码,vscode添加提示,ubuntu命令美化,tomcat8 面试,赤兔sqlite+注册码,爬虫下载安全性怎么样,php 小网站,seo推广的后期优化,平台式网站模板,手机京东网站模板下载安装lzw
功能上，本程序可以实现无限级留言与回复，即对留言回复，对回复的留言回复。当然你也可以作有限制的控制，使其只对留言回复，关键是在模板代码中去掉回复的留言中的“回复该留言”即可。欢迎去拍砖！
安卓音乐播放器 源码,ubuntu系统刷xp,tomcat的输出日志乱码,mac版爬虫,php卫星开发方向,百度seo优化排名需要多长时间lzw
程序效果下图例：
ace admin 源码,ubuntu多硬盘安装,web项目部署tomcat,爬虫scrapy管道,php 批量执行lonux命令,证券SEOlzw
