PHP＋TEXT留言本(五)
现在我们来讲一下reply.php的代码:---------------------------------//reply.php
<?
function check_strlen_long($txt){$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.未完待续...
