我对PHP很陌生，我正在使用简单的表单在主页上发帖给我发送电子邮件。虽然PHP邮件（）已被彻底检查，但我收到了空邮件
这是形式：
<form data-abide action="anfrage.php" method="post">
\t <fieldset>
\t \t <div class="row">
\t \t \t <div class="large-12 columns">

</form>的anfrage.php看起来是这样的：
<?php

虽然恕我直言，没有空的电子邮件应打通了我，我不断获取像这样的EMails：
To: [email protected]
From: [email protected]
Subject:
Body:
Firma:
Ansprechpartner: Herr 59d4f7714f4d7
Adresse:
Telefonnummer:
Anfrage:
Someties它只是一个电子邮件一天，有时是三十+。
我不知道为什么我继续得到那些EMails。 你有什么想法如何避免它？ 或者你知道我的anfrage.php中存在安全问题吗？
在此先感谢！
无论如何，看到它是垃圾邮件，你的第一个应该是一个验证码（不管是基本的）。 - 表单检查逻辑有点难以遵循;太多的地方变数。应该直接在'$ _POST'中工作，并使用一些散列运行函数/并生成最终模板。 - 其他：让它制作一个带有POST值的日志文件，以及最终的$ body结果。 – mario
