PHP访问加密

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

1.PHP

<?php
session_start();
if(isset($_POST['password']) && $_POST['password'] == 'admin'){
    $_SESSION['ok'] = 1;
    header('location:?');
}
if(!isset($_SESSION['ok'])){
    exit('
        <form method="post">
            密码：<input type="password" name="password" />
            <input type="submit" value="登陆" />
        </form>
    ');
}
?>

2.JavaScript

<script type="text/javascript">
    loopy();
            function loopy() {
                var sWord = prompt("输入正确密码才能登陆!","");
                var password = "123456";
                var isCancle = false;
                while(sWord!=password){
                    if(sWord==null){
                        isCancle = true;
                        break;
                    }else{
                        sWord = prompt("输入正确密码才能登陆!","");
                    }
                }
                if(!isCancle){
                    alert("密码正确谢谢你的光临！");
                }else{
                    location.replace("about:blank");
                    window.close();
                }
            }
</script>
