无法通过联系表单接收电子邮件，这是我的代码

Question

我无法接收电子邮件。这是我的代码。我正在尝试找到我的错误，但我无法找到。所以有人帮我解决这个问题。我对我的代码感到怀疑。我在我的php文件中的代码。我的邮件（）  函数返回true，我修改了我的xamp配置文件。

  <?php
    require("connection.php");
    ?>
    <?php

      if(isset($_REQUEST))
      {
          $first = $_REQUEST['firstname'];
          $middle = $_REQUEST['middlename'];
          $last = $_REQUEST['lastname'];
          $email = $_REQUEST['email'];
          $phone = $_REQUEST['phone'];
          $message =$_REQUEST['message'];
          $query=" INSERT INTO `contact`(`id`,`first-name`, `middle-name`, `last-name`, `email`, `phone`, `message`) VALUES ('','$first','$middle','$last','$email','$phone','$message')";
          $result = mysql_query($query);
          if($result)
          {
            echo "data entered";
          }
          else
          {
            echo "data is not entered";
          }
