php頁面怎麼設定頁面訪問密碼,PHP為任意頁面設定訪問密碼

為你的頁面支援加密訪問無論什麼程式只要是PHP程式都是支援這程式碼的,來實現加密訪問你的加密頁面或文章等等的頁面,不保證其他程式可以正常使用麻煩先測試!

密碼正確才能進去頁面,進入後會存下cookies值,下一次登入的時候則不需要再次輸入了;

如果不想給人看了,只需要更改密碼,cookies就會立即失效,必須要重新登陸才能看。

安裝方法:

1.新建PHP檔案,命名為:MkEncrypt.php,把下面程式碼放進這個新建為PHP檔案裡面

<?php

/********************************************
* 使用方法:
* 
* 1、將本段程式碼儲存為 MkEncrypt.php
* 
* 2、在要加密的頁面前面引入這個 php 檔案 
* require_once('MkEncrypt.php');
* 
* 3、設定頁面訪問密碼 
* MkEncrypt('頁面密碼');
* 
*******************************************
*/ // 密碼 Cookie 加密鹽 if(!defined('MK_ENCRYPT_SALT')) define('MK_ENCRYPT_SALT', 'Kgs$JC!V'); /** * 設定訪問密碼 * * @param $password 訪問密碼 * @param $pageid 頁面唯一 ID 值,用於區分同一網站的不同加密頁面 */ function MkEncrypt($password, $pageid = 'default') { $pageid = md5($pageid); $md5pw = md5(md5($password).MK_ENCRYPT_SALT); $postpwd
= isset($_POST['pagepwd']) ? addslashes(trim($_POST['pagepwd'])) : ''; $cookiepwd = isset($_COOKIE['mk_encrypt_'.$pageid]) ? addslashes(trim($_COOKIE['mk_encrypt_'.$pageid])) : ''; if($cookiepwd == $md5pw) return; // Cookie密碼驗證正確 if($postpwd == $password) { // 提交的密碼正確 setcookie('mk_encrypt_' . $pageid
, $md5pw, time() + 3600000, '/'); return; } ?> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <meta charset="UTF-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="renderer" content="webkit"> <meta name="author" content="mengkun"> <meta name="viewport" content="width=device-width, initial-scale=1.0, minimum-scale=1.0, maximum-scale=1.0, user-scalable=no"> <title>該頁面已被加密</title> <style type="text/css"> *{font-family:"Microsoft Yahei",微軟雅黑,"Helvetica Neue",Helvetica,"Hiragino Sans GB","WenQuanYi Micro Hei",sans-serif;box-sizing:border-box;margin:0px;padding:0px;font-size:14px;-webkit-transition:.2s;-moz-transition:.2s;-ms-transition:.2s;-o-transition:.2s;transition:.2s} html,body{width:100%;height:100%} body{background-color:#F4F6F9;color:#768093} input,button{font-size:1em;border-radius:3px;-webkit-appearance:none} input{width:100%;padding:5px;box-sizing:border-box;border:1px solid #e5e9ef;background-color:#f4f5f7;resize:vertical} input:focus{background-color:#fff;outline:none} button{border:0;background:#6abd09;color:#fff;cursor:pointer;opacity:1;user-select:none} button:hover,button:focus{opacity:.9} button:active{opacity:1} .main{width:100%;max-width:500px;height:300px;padding:30px;background-color:#fff;border-radius:2px;box-shadow:0 10px 60px 0 rgba(29,29,31,0.09);transition:all .12s ease-out;position:absolute;left:0;top:0;bottom:0;right:0;margin:auto;text-align:center} .alert{width:80px} .mk-side-form{margin-bottom:28px} .mk-side-form input{float:left;padding:2px 10px;width:77%;height:37px;border:1px solid #ebebeb;border-right-color:transparent;border-radius:2px 0 0 2px;line-height:37px} .mk-side-form button{position:relative;overflow:visible;width:23%;height:37px;border-radius:0 2px 2px 0;text-transform:uppercase} .pw-tip{font-weight:normal;font-size:26px;text-align:center;margin:25px auto} #pw-error {color: red;margin-top: 15px;margin-bottom: -20px;} .return-home{text-decoration:none;color:#b1b1b1;font-size:16px} .return-home:hover{color:#1E9FFF;letter-spacing:5px} </style> </head> <body> <div class="main"> <svg class="alert" viewBox="0 0 1084 1024" xmlns="http://www.w3.org/2000/svg" width="80" height="80"> <defs><style/></defs> <path d="M1060.744 895.036L590.547 80.656a55.959 55.959 0 0 0-96.919 0L22.588 896.662a55.959 55.959 0 0 0 48.43 83.907h942.14a55.959 55.959 0 0 0 47.525-85.534zm-470.619-85.172a48.008 48.008 0 1 1-96.015 0v-1.567a48.008 48.008 0 1 1 96.015 0v1.567zm0-175.345a48.008 48.008 0 1 1-96.015 0V379.362a48.008 48.008 0 1 1 96.015 0v255.157z" fill="#FF9800"/> </svg> <form action="" method="post" class="mk-side-form"> <h2 class="pw-tip">該頁面已被加密</h2> <input type="password" name="pagepwd" placeholder="請輸入訪問密碼檢視" required><button type="submit">提交</button> <?php if($postpwd): ?> <p id="pw-error">Oops!密碼不對哦~</p> <script>setTimeout(function() {document.getElementById("pw-error").style.display = "none"}, 2000);</script> <?php endif; ?> </form> <a href="/" class="return-home" title="點選回到網站首頁">- 返回首頁 - </a> </div> </body> </html> <?php exit(); }

2.把下面的程式碼放進你要加密的PHP頁面裡面,比如你要給首頁:index.php 加密,就把下面程式碼放在index.php 的最前面

<?php

require_once('MkEncrypt.php');

MkEncrypt('1234');     //這個就是密碼

?>
