演示代码如下：

一. 表单页面

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Frameset//EN">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=GBK">
<title>Insert title here</title>
</head>
<body>
<form action="Demo12.php" method="post">
  Name:<input type="text" name="username"/></br>
  Age:<input type="text" name="age"/></br>
  Email:<input type="text" name="email"/></br>
  Password:<input type="password" name="pwd"/></br>
  <input type="submit" name="send" value="提交"/>
</form>
</body>
</html>

二数据处理页面

<?php
header("Content-type: text/html; charset=GBK");
$username=$_POST['username'];
if(!isset($_POST["send"]) || $_POST["send"] !='提交'){
header("Location:Demo13.php");
exit;
}else{
$username=$_POST['username'];
// $password=$_POST["pwd"];
$password=$_COOKIE['password'];
$email=$_POST["email"];
$age=$_POST["age"];
if(strlen($password)<5){
  echo "<script>alert('密码长度不能小于5');history.back()</script>";
  exit;
}else{
  setcookie("username",$username,time()+7*224*60*60);
  setcookie("password",$password,time()+7*224*60*60);
  session_start();
  $_SESSION['password']=$password;
  header("Location:Demo14.php");
}

}
?>

三，处理成功，跳转从Cookie,Session中获取数据，展现

<?php
header("Content-type: text/html; charset=GBK");
session_start();
echo "重Cookie中获取的用户名：".$_COOKIE["username"];
echo "从Session中获取的密码：".$_SESSION["password"];
echo "从Cookie中获取的密码：".$_COOKIE["password"];
