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"; } 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); $guestcontent = "<tr><td><font color=#AB00E1>留言内容:</font><br><!--content>$message<!--endcontent> "; $guestcontent=$guestcontent."<br><font color=#6633FF>留言人大名:</font><!--name>$name<!--endname> "; if ($email !="") {$guestcontent=$guestcontent."<br><font color=#9900CC>电子信箱</font><a href=\"mailto:$email\"><!--email>$email<!--endemail></a>"."$space";} if ($homepage !="http://") {$guestcontent=$guestcontent."<font color=#9900CC>主页:</font>$hompage<a href=\"$homepage\"><!--homepage>$homepage<!--endhomepage></a>";} $guestcontent=$guestcontent."<br><font color=#0000FF>时间:$time 来自:<!--from>$from<!--endfrom> $ip</font>"; $guestcontent=ereg_replace(chr(10),"",$guestcontent); $guestcontent=$guestcontent."<hr size=1></td></tr>\n"; $fp=fopen($guestfile,"a"); fputs($fp,$guestcontent); fclose($fp); } } ?> <html> <head> <title>zihanonlinegbook</title> <style> <!-- A:link {text-decoration: none ; color:0000ff} A:visited {text-decoration: none; color:004080} A:active {text-decoration: none} A:hover {text-decoration: underline; color:ff0000} BODY {FONT-SIZE:10pt} TH {FONT-SIZE:10 pt} TD {FONT-SIZE: 10pt} TEXTAREA { FONT-FAMILY: "宋体"; FONT-SIZE: 10pt; } --> </style> <body bgcolor=#FFFFFD background="bg.jpg"> <div align="center"> <?
