Hight.php完整代码如下：

<?php
            
    if (isset($_GET['Change'])) {
    
        // Turn requests into variables
        $pass_curr = $_GET['password_current'];
        $pass_new = $_GET['password_new'];
        $pass_conf = $_GET['password_conf'];

        // Sanitise current password input
        $pass_curr = stripslashes( $pass_curr );
        $pass_curr = mysql_real_escape_string( $pass_curr );
        $pass_curr = md5( $pass_curr );
        
        // Check that the current password is correct
        $qry = "SELECT password FROM `users` WHERE user='admin' AND password='$pass_curr';";
        $result = mysql_query($qry) or die('<pre>' . mysql_error() . '</pre>' );

        if (($pass_new == $pass_conf) && ( $result && mysql_num_rows( $result ) == 1 )){
            $pass_new = mysql_real_escape_string($pass_new);
            $pass_new = md5($pass_new);

            $insert="UPDATE `users` SET password = '$pass_new' WHERE user = 'admin';";
            $result=mysql_query($insert) or die('<pre>' . mysql_error() . '</pre>' );
                        
            $html .= "<pre> Password Changed </pre>";        
            mysql_close();
        }
    
        else{        
            $html .= "<pre> Passwords did not match or current password incorrect. </pre>";            
        }

    }
