现在我们来讲一下reply.php的代码:

---------------------------------

//reply.php

<?

$len=strlen($txt);

$count=0;

for ($i=0;$i<$len;$i++)

{

if (ord($txt[$i])<128)

{ $count=$count+1;}

if (ord($txt[$i])==10 or ord($txt[$i])==32)

{$count=0;}

if ($count>=60)

{

$txt[$i]="n";

$count=0;

}

}

return $txt;

}

function encode ($txt)

{

$txt=strip_tags($txt);

$txt=htmlspecialchars($txt);

$message=StripSlashes($txt);

return $message;

}

$content=file("guest.txt");

$disptext=$content[$record-1];

if ($job=="addreply" and $replyname!="" and $replycontent!="")

{

$content=file("guest.txt");

$count=count($content);

$time = date(Y年m月d日H小时i分);

$ip=$REMOTE_ADDR;

$replycontent=StripSlashes($replycontent);

$replyname=encode($replyname);

$replycontent=htmlspecialchars($replycontent);

$replycontent=check_strlen_long($replycontent);

$replycontent=nl2br($replycontent);

$replycontent=ereg_replace(chr(10),"",$replycontent);

$content[$record-1]=substr($content[$record-1],0,strlen($content[$i])-1); $content[$record-1]=$content[$record-1]."<!--reply><tr><td colspan=4><ul><font color=#AB00E1>回复内容:</font><br>".$replycontent."<br>回复人大名:".$replyname."<br><font color=#CC33FF>时间:$time 来自:$ip</font></ul><hr size=1 color=blue></td></tr>n";

$fp=fopen("guest.txt","w");

for ($i=0;$i<$count;$i++)

{

fputs($fp,$content[$i],strlen($content[$i]));

}

echo "<meta http-equiv=Refresh content=1;url=guest.php>";

exit;

到此为止,php的代码我们已经写完,剩下的是您要作一个留言本的本头和底部 您可以设计任何的样式.不过记得在本头上面要有至少3个连接:查看 返回主页 发邮件.这样您的留言本系统才算完整.不过由于这是一文本的留言本,所以您不用担心数据库的问题,您只要再写一个guest.txt的文件就完整了.虽然这个留言本没有mysql等等,可是功能仍然不错.而且是完全属于您自己的留言本.好了,下一节我们将为您讲述guest.txt的建立和上传留言本的几个重要步骤.
