PHP電子郵件形式 - 定義發件人

Question

我試圖創建一個HTML表單，這將最終使用folling PHP代碼發送電子郵件：

<?php 

$name = $_POST['name']; 
$email = $_POST['email']; 
$subject = $_POST['subject']; 
$message = $_POST['message']; 

$destinationemail = "myemail@domain.com"; 

$emailcontent = "Name: {$name}\n\nE-Mail: {$email}\n\nMessage: {$subject}\n{$message}"; 
$subject = "Contact from Domain.com"; 
$from = $email; 

mail($destinationemail, $subject, $emailcontent) or die("Error!"); 
echo "Thank you $name!"; 

?> 

的問題是，每次我收到一封電子郵件，我就好像是從一個我認爲是Webhost的普通電子郵件中發出的郵件。

htgkaylg@server776.web-hosting.net 
<htgkaylg@server776.web-hosting.net> 
dom 08/10/2017, 18:40 
Você; 

我想它要接收這樣的事：

myemail@domain.com 
<myemail@domain.com> 
dom 08/10/2017, 18:40 
Você; 

這可能嗎？

謝謝 維克托•

您必須使用標題爲（）函數在郵件第四個參數。 添加此行並更改郵件如下：

$headers = "From:" . $from . "\r\n"; 

mail($destinationemail, $subject, $emailcontent, $headers) or die("Error!");
