<!doctype html>
<html lang="en">
   <head>
      <meta charset="utf-8">
      <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
  
      <title>Send Reset Password Link with Expiry Time in PHP MySQL</title>
       <!-- CSS -->
       <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css">
   </head>
   <body>
      <div class="container">
          <div class="card">
            <div class="card-header text-center">
              Send Reset Password Link with Expiry Time in PHP MySQL
            </div>
            <div class="card-body">
              <form action="password-reset-token.php" method="post">
                <div class="form-group">
                  <label for="exampleInputEmail1">Email address</label>
                  <input type="email" name="email" class="form-control" id="email" aria-describedby="emailHelp">
                  <small id="emailHelp" class="form-text text-muted">We'll never share your email with anyone else.</small>
                </div>
                <input type="submit" name="password-reset-token" class="btn btn-primary">
              </form>
            </div>
          </div>
      </div>

   </body>
</html>

Step 4: Send Link in Email and Store Token with Expire time PHP file

In this step, create new PHP file named password-reset-token.php. This file PHP code will generate a reset password link with expire time. And then send this link via email and store it into MySQL DB.

To update the following php code into password-reset-token.php file:

<?php
if(isset($_POST['password-reset-token']) && $_POST['email'])
{
    include "db.php";
    
    $emailId = $_POST['email'];

    $result = mysqli_query($conn,"SELECT * FROM users WHERE email='" . $emailId . "'");

    $row= mysqli_fetch_array($result);

  if($row)
  {
    
     $token = md5($emailId).rand(10,9999);

     $expFormat = mktime(
     date("H"), date("i"), date("s"), date("m") ,date("d")+1, date("Y")
     );

    $expDate = date("Y-m-d H:i:s",$expFormat);

    $update = mysqli_query($conn,"UPDATE users set  password='" . $password . "', reset_link_token='" . $token . "' ,exp_date='" . $expDate . "' WHERE email='" . $emailId . "'");

    $link = "<a href='www.yourwebsite.com/reset-password.php?key=".$emailId."&token=".$token."'>Click To Reset password</a>";

    require_once('phpmail/PHPMailerAutoload.php');

    $mail = new PHPMailer();

    $mail->CharSet =  "utf-8";
    $mail->IsSMTP();
    // enable SMTP authentication
    $mail->SMTPAuth = true;                  
    // GMAIL username
    $mail->Username = "[email protected]";
    // GMAIL password
    $mail->Password = "your_gmail_password";
    $mail->SMTPSecure = "ssl";  
    // sets GMAIL as the SMTP server
    $mail->Host = "smtp.gmail.com";
    // set the SMTP port for the GMAIL server
    $mail->Port = "465";
    $mail->From='[email protected]';
    $mail->FromName='your_name';
    $mail->AddAddress('reciever_email_id', 'reciever_name');
    $mail->Subject  =  'Reset Password';
    $mail->IsHTML(true);
    $mail->Body    = 'Click On This Link to Reset Password '.$link.'';
    if($mail->Send())
    {
      echo "Check Your Email and Click on the link sent to your email";
    }
    else
    {
      echo "Mail Error - >".$mail->ErrorInfo;
    }
  }else{
    echo "Invalid Email Address. Go back";
  }
}
?>

</div>
<div class="card-body">
<?php
if($_GET['key'] && $_GET['token'])
{
include "db.php";
$email = $_GET['key'];
$token = $_GET['token'];
$query = mysqli_query($conn,
"SELECT * FROM `users` WHERE `reset_link_token`='".$token."' and `email`='".$email."';"
);
$curDate = date("Y-m-d H:i:s");
if (mysqli_num_rows($query) > 0) {
$row= mysqli_fetch_array($query);
if($row['exp_date'] >= $curDate){ ?>
<form action="update-forget-password.php" method="post">
<input type="hidden" name="email" value="<?php echo $email;?>">
<input type="hidden" name="reset_link_token" value="<?php echo $token;?>">
<div class="form-group">
<label for="exampleInputEmail1">Password</label>
<input type="password" name='password' class="form-control">
</div>                
<div class="form-group">
<label for="exampleInputEmail1">Confirm Password</label>
<input type="password" name='cpassword' class="form-control">
</div>
<input type="submit" name="new-password" class="btn btn-primary">
</form>
<?php } } else{

$password = md5($_POST['password']);
$query = mysqli_query($conn,"SELECT * FROM `users` WHERE `reset_link_token`='".$token."' and `email`='".$emailId."'");
$row = mysqli_num_rows($query);
if($row){
mysqli_query($conn,"UPDATE users set  password='" . $password . "', reset_link_token='" . NULL . "' ,exp_date='" . NULL . "' WHERE email='" . $emailId . "'");
