現在我們來講一下reply.php的代碼:
---------------------------------
//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小時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>回復內容:</font><br>".$replycontent."<br>回復人大名:".$replyname."<br><font color=#CC33FF>時間:$time 來自:$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;

}
