所以我尝试使用php，MySQL和使用UwAmp服务器在登录表单上添加密码重置功能。这必须以这种方式完成，因为我需要将项目放在我的讲师等可以访问的大学UwAmp文件空间中。
我已尝试过以下代码，但显然，它没有发送电子邮件。我是否必须安装邮件客户端才能将内容发送到电子邮件帐户？或者这是否真的可以在本地主机上完成，我应该在单独的页面上模仿电子邮件功能？
<?
include'config.php';
if(isset($_GET['action']))
{
if($_GET['action']=="reset")
{
$encrypt = mysqli_real_escape_string($connection,$_GET['encrypt']);
$query = "SELECT id FROM users where md5(90*13+id)='".$encrypt."'";
$result = mysqli_query($link,$query);
$Results = mysqli_fetch_array($result);
if(count($Results)>=1)
{
}
else
{
$message = 'Invalid key please try again. <a href="http://demo.phpgang.com/login-signup-in-php/#forget">Forget Password?</a>';
}
}
}
elseif(isset($_POST['action']))
{
$encrypt = mysqli_real_escape_string($connection,$_POST['action']);
$password = mysqli_real_escape_string($connection,$_POST['password']);
$query = "SELECT id FROM users where md5(90*13+id)='".$encrypt."'";
$result = mysqli_query($connection,$query);
$Results = mysqli_fetch_array($result);
if(count($Results)>=1)
{
$query = "update users set password='".md5($password)."' where id='".$Results['id']."'";
mysqli_query($connection,$query);
$message = "Your password changed sucessfully <a href=\"http://demo.phpgang.com/login-signup-in-php/\">click here to login</a>.";
}
else
{
$message = 'Invalid key please try again. <a href="http://demo.phpgang.com/login-signup-in-php/#forget">Forget Password?</a>';
}
}
else
{
header("location:login.php");
}
重置传球。还没有被使用，还包含一些错误，比如不使用我的配置文件中的$ link变量，只是为了显示我正在尝试的内容。
