PHP邮件功能未从标题正确设置

我有一个php邮件功能，可以发送包含联系表单中内容的电子邮件。但是当我在我的网站上发送此电子邮件时。而不是from标头是输入的电子邮件地址，它是username@srv30.000webhost.com，我不知道为什么。我的PHP邮件功能如下。

$ email是用户输入的电子邮件。

我对PHP还是很陌生，所以对您的帮助将不屑一顾。谢谢

我相信这条线

$result = @mail($to, $subject, $message, $from);

应该固定为此

$result = sendmail($to, $subject, $message, $from);

并将您的sendmail函数更改为此

function sendmail($to, $subject, $message, $from) {
    $headers = "MIME-Version: 1.0" . "\r\n";
    $headers .= "Content-type:text/html;charset=iso-8859-1" . "\r\n";
    $headers .= 'From: ' . $from . "\r\n";
    $headers .= 'Reply-To: ' .$from . "\r\n";
    $headers .= 'X-Mailer: PHP/' . phpversion();
    @mail($to, $subject, $message, $headers); 

    if ($result) return 1;
    else return 0;
}

在这里，您使用的是$ email，但也许应该使用$ from。您的函数需要$ to，$ subject，$ message，$ from。

另外，您可能应该更改一下代码

function sendmail($to, $subject, $message, $from) {
    $headers = "MIME-Version: 1.0" . "\r\n";
    $headers .= "Content-type:text/html;charset=iso-8859-1" . "\r\n";
    $headers .= 'From: ' . $from . "\r\n";
    $headers .= 'Reply-To: ' .$from . "\r\n";
    $headers .= 'X-Mailer: PHP/' . phpversion();
    if(mail($to, $subject, $message, $headers)){
        return 1;
    } 
    return 0;
}

sendmail是用于发送电子邮件的UNIX应用程序二进制文件。用PHP编写自己的sendmail函数不会执行任何操作。我相信，默认情况下，PHP邮件功能在Linux上使用sendmail，而在Windows上，则需要配置SMTP。但是，在发送电子邮件时，这不是问题。也许您应该重命名该函数，以免您意外混合这些内容。

另外这里是整个代码的重写，也许您可以学到一两个东西:)

$post = false;
// flag to indicate which method it uses. If POST set it to 1
if (isset($_POST['Name'])) {
    $post = true;
}

$name = (isset($_GET['Name'])) ? $_GET['Name'] : $_POST['Name'];
$email = (isset($_GET['Email'])) ? $_GET['Email'] : $_POST['Email'];
$phone = (isset($_GET['Phone'])) ? $_GET['Phone'] : $_POST['Phone'];
$comment = (isset($_GET['Comment'])) ? $_GET['Comment'] : $_POST['Comment'];


// Simple server side validation for POST data, of course, you should validate the email
if (!$name) {
    $errors[] = 'Please enter your name.';
}
if (!$email) {
    $errors[] = 'Please enter your email.';
}
if (!$comment) {
    $errors[] = 'Please enter your comment.';
}
// if the errors array is empty, send the mail
if (count($errors) == 0) {

    // recipient
    $to = 'example@example.com';
    // sender
    $from = $name . ' <' . $email . '>';

    // subject and the html message
    $subject = 'Comment from ' . $name;
    $message = '<!DOCTYPE html>
<html>
<head></head>
<body>
<table>
    <tr><td>Name</td><td>' . $name . '</td></tr>
    <tr><td>Email</td><td>' . $email . '</td></tr>
    <tr><td>Phone</td><td>' . $phone . '</td></tr>
    <tr><td>Comment</td><td>' . nl2br($comment) . '</td></tr>

    $headers = "MIME-Version: 1.0" . "\r\n";
    $headers .= "Content-type:text/html;charset=iso-8859-1" . "\r\n";
    $headers .= 'From: ' . $from . "\r\n";

    $headers .= 'X-Mailer: PHP/' . phpversion();
    $mailSuccess = mail($to, $subject, $message, $headers);

        if ($mailSuccess) {
