Answer 1

$message = $start1 . $sender . $content . $sufix

应该是

$message = $start1 . $sender . $content . $sufix;

这就是你收到错误的原因

解析错误：语法错误，意外的T_STRING 第27行/home/R6iJfd/prog.php

Answer 2

$from应该是标题。所以，你需要写这个：

$from = 'From: '.$_POST['Email'];

您还有其他问题，但与邮件无关：

if ($_POST['Gender'] = 'M') {

应该是：

if ($_POST['Gender'] == 'M') {

Answer 3

您遇到编程问题（将抛出错误）

或

您需要在PHP.INI确认您的邮件设置是否正确，这取决于您的服务器软件是否配置为发送邮件，而不是PHP中的发送。

一旦确定您的服务器配置正确，您的PHP mail()就可以正常工作

修改

您也注意到此行中缺少;：

$message = $start1 . $sender . $content . $sufix

mail（）函数不能在php上运行
