我最近在 w3resource 网站上阅读了一篇关于如何通过 PHP 验证表单的有趣文章，该文章介绍了如何通过 PHP 验证表单，但其中没有包含将数据发送到电子邮件地址的方法。以下代码来自下载的示例（http://www.w3resource.com/php/form/php-form-validation.php）

我对 PHP 编码不太感兴趣，但是如果我可以在上面附加一个电子邮件地址并在验证后接收数据输入，那就太好了。任何帮助将不胜感激....

所以，给你 - 一步一步，

Step 1: declare the mail address to whom you want to send mail.
Step 2: write subject of the mail. 
Step 3: collect data from POST so that you can write them to the body of mail. 
Step 4: declare the mail id from which the mail is coming. 
Step 5: sent mail with PHP mail() function.

代码在这里
