HTML / PHP联系表单不会发送到我的电子邮件，但会转到成功页面

Question

您好我是stackoverflow的新手，所以请原谅我，如果我做错了什么。我对PHP知之甚少。所以我有这个联系表单，我想在用户提交时发送到我的电子邮件。我一直在墙上撞了一会儿，两个文件都上传到服务器，并且在同一个目录中。表单转到成功页面，但我没有收到电子邮件。请帮帮我。

如果有帮助，表单的链接也是http://xtcracingteam.com/apply.html。

这是HTML

     <form method="post" action="http://xtcracingteam.com/send_form_email.php">

                    <label class="first-name">
