（本文来源于图老师网站，更多请访问http://www.tulaoshi.com/php/）在许多时候，我们需要收集上网者和网友们的意见。例如：新版页面与旧版页面的比较；对某一事情的看法；对体育比赛结果的预测等等。这时候，你需要一个非常有效的网上调查系统。使用PHP就可以非常方便地实帜愕恼庖还瓜搿?
8.1 投票系统（mypolls.php3）：
<?
$status=0;
if(isset($polled)&&($polled=="c-e")){
$status=1;
}
#echo "$status";
if(isset($poll)&&($status==0)){
setcookie("polled","c-e",time() 86400,"/");#time=24h
}
?
<html
<head
<title新版页面调查</title
<meta http-equiv="Content-Type" content="text/html; charset=gb2312"
<style type="text/css"
<!--
.tb { border="1" bordercolor="#009933" cellspacing="0" font-size: 9pt; color: #000000}
.head { font-family: "宋体"; font-size: 12pt; font-weight: bold; color: #009933; text-decoration: none}
.pt9 { font-size: 9pt}
a.p9:link { font-size: 9pt; color: #000000; text-decoration: none}
a.p9:visited { font-size: 9pt; color: #000000; text-decoration: none }
a.p9:hover { font-size: 9pt; color: #FF0000; text-decoration: underline}
a.p9:active { font-size: 9pt; color: #FF0000; text-decoration: underline }
--
</style
</head
<body bgcolor="#FFFFFF"
<div class="head"与旧版页面相比较您觉得新版页面：</div<br
<?
if(!isset($submit)){
?
<form action="myPolls.php3" method="get"
<input type="radio" name="poll_voteNr" value="1" checked
<span class="pt9"信息量更大</span <br
