使用方法和步骤

新建一个MkEncrypt.php文件在根目录下或者同级目录下。

MkEncrypt.php里面添加以下代码：

<?php
if(!defined(\’MK_ENCRYPT_SALT\’))
define(\’MK_ENCRYPT_SALT\’, \’Kgs$JC!V\’);
/**
* 设置访问密码
* @param $password 访问密码
* @param $pageid 页面唯一 ID 值，用于区分同一网站的不同加密页面
*/
function MkEncrypt($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 == $md5pw) return; // Cookie密码验证正确
if($postpwd == $password) { // 提交的密码正确
setcookie(\’mk_encrypt_\’ . $pageid, $md5pw, time() + 3600000, \’/\’);
return;
}
?>

<?php if($postpwd): ?>
<p id=\”pw-error\”>密码不对哦~</p>

</html>
<?php
exit();
}

把下面的代码放在你需要加密的页进行调用

<?php
require_once(\’MkEncrypt.php\’);
MkEncrypt(\’123456\’);
?>

MkEncrypt(‘123456’);括号里面123456修改成你需要设置的密码。

密码正确才能进去页面，进入后会存下cookies值，下一次登录的时候则不需要再次输入了，只要是PHP程序都是支持这段代码的。

方法补充

除了上文的方法，小编还为大家整理了一些PHP为页面加密的方法，希望对大家有所帮助

对某些php页面设置单独的访问密码，如果密码不正确则无法查看内容，相当于对页面进行了一个加密。只需要将以下php文件包含在你需要设置独立访问密码的最前面就可以了。

recheck.php

<html>
<head>
<meta http-equiv=\”Content-Type\” content=\”text/html; charset=utf-8\” />
<title>title</title>
<style>
#divcss{margin:300 auto;width:400px;height:40px;}
#footer {
height: 40px;
line-height: 40px;
position: fixed;
bottom: 0;
width: 100%;
text-align: center;
background: #373d41;
color: #ffffff;
font-family: Arial;
font-size: 16px;

letter-spacing: 1px;
}
a {text-decoration: none}
</style>
</head>
<body>
<?php
//所有需要输出二次密码打开的页面，只需要将本php文件进行包含即可
$url = 'http://'.$_SERVER['SERVER_NAME'].':'.$_SERVER[\”SERVER_PORT\”].$_SERVER[\”REQUEST_URI\”];
//echo $url;
if (!session_id()){session_start();};
if(isset($_GET['close'])){
$url = $_GET['url'];
unset($_SESSION['recheck']);
}
if(isset($_POST['password']) && $_POST['password'] == '123456'){
$_SESSION['recheck'] = 1;
header('location:'.$url);
}
if(!isset($_SESSION['recheck'])){
exit('<div id=\”divcss\”>
<form method=\”post\”>
请输入独立访问密码：<input type=\”password\” name=\”password\” />
<input type=\”submit\” value=\”确定\” />（密码：123456）
</form>
</div>
');
}
?>
<div id=\”footer\”><a href=\”?close=yes&url=<?php echo $url?>\” rel=\”external nofollow\” ><font color=\”#FFFFFF\”>安全退出本页面</font></a></div>
</body>
