asp cgi one and complex database Now of Know network importance

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.笔者现在向您推荐动站指南,(http://www.knowsky.com)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="出错了!!!姓名和留言内容必填";
  }
  else
{
#写入数据
$space = " ";
$time = date(Y年m月d日H小时i分);
$ip=$REMOTE_ADDR;
$name=encode($name);
$homepage=encode($homepage);
$from=encode($from);
$email=encode($email);
$message=StripSlashes($message);
$message=htmlspecialchars($message);
$message=check_strlen_long($message);
$message=nl2br($message);
$guestcontent = "

留言内容:



 
  include(head.htm);?>
 
   
     
      if ($errorm)
      {
      echo "";
      echo "";
      echo "";
      }
