随时给自己贴的图片加文字的php代码一个简单的PHP投票程序源码

小弟初学PHP，编了一个留言板程序，自我感觉良好，故厚着脸皮放了上来，请各位大哥指正。源程序如下：
<?php
//文件名：guest.php
//设定部分
$guestfile="guest";//纪录留言的文本文件
$home="index.html";//返回的主页
$imagedir="image"; //图像文件的目录
$backimage=$imagedir."/upload/tech/20091012/20091012014114_bca82e41ee7b0833588399b1fcd177c7.gif";//背景图像
$backcolor="#ceffff";//背景颜色,在$backimage=""时起作用
?>
<html>
<head>
<?php
if($QUERY_STRING!="") {
$page = $QUERY_STRING;
} else {
$page = 1;
}
if($mode=="add"){
$name=htmlspecialchars(trim($name));
$title=htmlspecialchars(trim($title));
$data=nl2br(htmlspecialchars($data));
$data=str_replace("r","",$data);
$data=str_replace("x0A","",$data);
$data=str_replace(" "," ",$data);
if($data=="") $data=" ";
$e_mail=trim($e_mail);
if($e_mail=="") $e_mail=0;
$url=trim($url);
if($url=="http://" || $url=="") $url=0;
$time=date("Y")."年".date("m")."月".date("d")."日[".date("H").":".date("i").":".date("s")."]";
if($name=="" || $title==""){
echo "<script Language="JavaScript">n";
echo " alert("请至少输入姓名与留言标题。");n";
echo "history.back();";
echo "</script></head></html>n";
exit;
}
$adddata=$name."t".$e_mail."t".$url."t".$title."t".$data."t".$icon."t".$time."n";
if(file_exists($guestfile)){
$filebuffer=file($guestfile);
if(sizeof($filebuffer)>100){
for($i=0;$i<100;$i++)
$newbuffer[i]=$filebuffer[i];
}
else{
$newbuffer=$filebuffer;
}
$fp=fopen($guestfile,"w");
fputs($fp,$adddata);
fclose($fp);
$buffer=implode("",$newbuffer);
$fp=fopen($guestfile,"a");
fputs($fp,$buffer);
fclose($fp);
