SQL结果未通过电子邮件发送

Question

我有一个忘记密码的php页面，如果他的电子邮件在数据库中，则会向用户发送密码。代码正在运行，但发送的电子邮件中的密码为空。我认为这是因为我没有把它转换为字符串，但我不知道该怎么做。我也在数据库中保存了密码，这会影响到什么吗？

盐：

<?php
  $salt1    = "qm&h*";
  $salt2    = "pg!@";
  $token    = hash('ripemd128', "$salt1$pass$salt2");
?>

忘记密码php页面：

<?php
$error = $email = "";

if (isset($_POST['email']))
  {
    $email = sanitizeString($_POST['email']);
    
    if ($email == "")
        $error = "Not all fields were entered<br>";
    else if (!filter_var($email, FILTER_VALIDATE_EMAIL)) 
      $error='Email is invalid';
    else
    {
      $resultE = queryMySQL("SELECT email FROM users WHERE email='$email'");

      $result_pass = queryMysql("SELECT * FROM users WHERE email='$email'");
  	  $row = $result_pass->fetch_array(MYSQLI_ASSOC);
  	  $user_pass = $row['[pass]'];

      if ($resultE->num_rows == 0)
      {
        $error = "<span class='error'>Email
                  error</span><br><br>";
      }else
      {
        $mail_to = $email;
        $subject = 'This is your registered password ';
        $body_message = 'Password: '."\n\n".$user_pass; //convert to string
        $mail_status = mail($mail_to, $subject, $body_message);
        if(isset($_SESSION['url'])) 
           $url = $_SESSION['url'];
        else 
           $url = "../../index.php"; 

        header("Location:$url"); 
      }
    }
  }
?>
