Php 我需要发件人在电子邮件主题中的电子邮件id

我的php脚本运行良好，但我想在电子邮件主题发送发件人地址。请指导我如何做

请告诉我在“$emailSbuject=$emailFeild的新订阅\r\n”中应该写什么

这是我的php脚本：

<?php
/* subject and email varialbles*/

$emailSbuject = "New Subscription from $emailFeild\r\n";
$webMaster = 'help@sample.com';
$emailSbuject2 = 'Thank you';
$client = ' $emailFeild\r\n';
/*gathering data variables*/

$emailFeild = $_POST['email'];

// admin message body
$body= <<<EOD
New subscriber is $emailFeild

EOD;

$textMessage = <<<EOD

<p style="margin-left:5px;font-family:Calibri"><img alt=""         src="http://www.intaxfin.com/images/Intaxfin_logo.png"></p>

         <p style="font-family:Calibri">Thank you for subscribing with us. Somebody will get back     to you as soon as possible.</p>

<p  style="font-size:x-small;color:#0099FF;font-family:Calibri">This e-mail was automatically     sent by Administration Directory and is for your reference. Please do not reply to this e-    mail address.<br>

EOD;
    $headers = "From: $emailFeild\r\n";
    $header = "From: $noreply@sample.com\nMIME-Version: 1.0\nContent-Type: text/html;     charset=utf-8\n";
    $success = mail($webMaster,$emailSbuject,$body,$headers);
    $success1 = @mail($emailFeild,$emailSbuject2,$textMessage,$header);
    /*Result*/

    $theResults = <<<EOD
EOD;

echo  "$theResults";

header("Location: thankyousubscribe.html");
exit;
?> 

---

注意：$client已使用$emailFeild变量启动，该变量在该行之后启动。请先启动变量，然后使用它。

先生，请帮助我@Bowdzone

$emailSbuject=“来自“$emailFeild”的新订阅。\r\n”@Bowdzone-thnx先生。它的工作非常好我的答案被选中了，现在我不知道为什么它被撤销了，我投了反对票…很抱歉，你的代码不起作用@鲍佐内给出了正确的答案。
 $emailFeild = $_POST['email'];
 $emailSbuject2 = "New Subscription from $emailFeild";
