一个php作的文本留言本的例子(一)

更新时间:2023-04-06 05:34:34 阅读：评论：0

大家知道,数据库对于网络来说的重要性.由于cgi的复杂,现在asp和php+mysql已经成为主流.几乎所有的个人网页都要用到留言本,可是申请的留言本很不稳定.这为网上的交流带来了诸多不便.所以,希望拥有自己的留言本的朋友越来越多.

但是,免费的个人主页支持asp和php的很少.笔者现在向您推荐奥索网,(http://www.oso.com.cn)支持php.这样您便有了能够拥有自己留言本的基础.现在,我就通过一个文本留言本的例子来讲述php的简单使用.

首先,我们先确定,留言的几个过程:写留言,发送,查看.(搜索)等等.而且对于斑竹来说,管理留言本又是不可或缺的.这样我们就不妨定位于6个php文件,1个文本文件.6个php文件分别为:guest.php manage.php reply.php sys.php del.php edit.php,1个文本文件为:guest.txt

先来看看guest.php的内容,你当然可以直接将下面的内容放到您的php网页里,请尊重作者的劳动,谢谢.

//guest.php:<?

require(“sys.php”);

if ($b1)

{

if($message==”” or $name==””)

{

$errorm=”<font color=red>出错了!!!</font>姓名和留言内容必填”;

}

$guestcontent=$guestcontent.”<hr size=1></td></tr>\n”;

$fp=fopen($guestfile,”a”);

fputs($fp,$guestcontent);
