PHP代码实现网页访问密码设置
```php <?php // 连接数据库 $servername = "localhost"; $username = "username"; $password = "password"; $dbname = "myDB"; $conn = new mysqli($servername, $username, $password, $dbname); if ($conn->connect_error) { die("连接失败： " . $conn->connect_error); } // 设置访问密码 $access_password = "your_access_password"; // 检查访问密码是否正确 if (isset($_POST['submit']) && isset($_POST['password'])) { if ($_POST['password'] == $access_password) { echo "访问密码正确，欢迎访问！"; } else { echo "访问密码错误，请重试。"; } } ?>
菜鸡源码自用的一段网页设置访问密码php代码，用户输入才能访问，可以用于简单的个人加密页面，或者防止攻击，效果如下图。
