再次分享一篇输入密码才可以浏览网页的php代码，密码功能代码都差不多，这款的UI好看点。
直接复制粘贴到需要加密的页面，就可以给网站开启了密码保护，让页面输入密码才能访问！
修改也非常简单，直接替换4行密码，替换48行要跳转的链接即可。
php代码示例
<?php
header('Content-type:text/html;charset=utf-8');
$password = "11px"; // 这里是正确密码
$p = "";
if(isset($_COOKIE["isview"]) && $_COOKIE["isview"] == $password){
$isview = true;
}else{
if(isset($_POST["pwd"])){
if($_POST["pwd"] == $password){
setcookie("isview",$_POST["pwd"],time()+3600*0.2);
$isview = true;
}else{
$p = (empty($_POST["pwd"])) ? "需要密码才能查看，请输入密码。" : "密码不正确，请重新输入。";
}
}else{
$isview = false;
$p = "源码来源www.hu6.cc";
}
}
if($isview){ ?>
