php 代码 100分
求一个用php做的注册和登录页面能提交到mysql的，端口是3307，数据库名是bbs，
表名是user-info，注册的是register.php 登录的是login.php
求代码，用来参考学习
回复讨论(解决方案)
这种代码网上很多吧，随便一搜一大把。
其实php的登录注册，说白了就是php执行select跟insert SQL语句，然后做些相应的跳转。
我想要的是代码，能给我提供学习
骚年，百度/google一下就有了，何必在这等别人给你写呢
随便下载个开源的你就可以看到了。
不是这缺就是哪个对方不对的，改起来麻烦，我对php还不是很熟悉，我是做java 我们部门要求掌握php的一些基础知识，所以喽
