上一次我们研究了guest.php文件.具体的问题还要求读者朋友自己深入的去实践,而且需要一些工具书来学习,如果您一点php的知识都没有,笔者奉劝您就不要想下看了,笔者没有太多的时间和篇幅去逐句探究一个php文件的用途和意义.好的,接下来我们来作edit.php这个文件.

暂无一个php作的文本留言本的例子(二)的评论...
稳了！魔兽国服回归的3条重磅消息！官宣时间再确认！
昨天有一位朋友在大神群里分享，自己亚服账号被封号之后居然弹出了国服的封号信息对话框。
这里面让他访问的是一个国服的战网网址，com.cn和后面的zh都非常明白地表明这就是国服战网。
而他在复制这个网址并且进行登录之后，确实是网易的网址，也就是我们熟悉的停服之后国服发布的暴雪游戏产品运营到期开放退款的说明。这是一件比较奇怪的事情，因为以前都没有出现这样的情况，现在突然提示跳转到国服战网的网址，是不是说明了简体中文客户端已经开始进行更新了呢？
