密码对,就可以看到指定内容, 密码不对就进不去；首次打开和关闭浏览器重新打开 都需要输入密码才可以访问，具体代码如下：<?php
$password = "3210";
$p = "";if(isset($_COOKIE["isview"]) and $_COOKIE["isview"] == $password){
$isview = true;}else{
if(isset($_POST["pwd"])){
if($_POST["pwd"] == $password){
setcookie("isview",$_POST["pwd"],time()+3600*3);$isview = true;}else{$p = (empty($_POST["pwd"])) ? "需要密码才能查看，请输入密码。" : "<div style=\"color:#F00;\">密码不正确，请重新输入。</div>";}
}else{$isview = false;$p = "请输入密码查看，获取密码可联系我。";}}?>
<?php if($isview){?>
