Question

我收到了“警告：无法修改标头信息 - 已经发送的标头（在第147行的/process_contact.php中已经开始输出）”，而在php中使用mail（）发送邮件给多用户。

    $from = "test@gmail.com";
    $adminmessage="You have received an email from ".$_POST['email'].
    $to = "test1@gmail.com";
    $subject = "Email Received for an Order";
    $message = '<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html>
    <head><meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"></head><body>

Answer 1

您已经echo编辑了某些内容后，您无法发送标题信息。有关如何解决此问题的信息，请参阅PHP output buffering。

删除它，它应该工作：

echo "Mail Sent.";

Answer 2

echo "Mail Sent.";
header('Location: reservation.php?sentok');

那个^

在任何情况下，无论如何回应一些东西然后直接重定向是没有意义的。您可以在Mail Sent

输出reservation.php

if(isset($_GET['sentok'])) echo 'Mail Sent.';

编辑：

我认为您的错误消息指出了语法错误：

$adminmessage="You have received an email from ".$_POST['email']. // <-- this
$to = "test1@gmail.com";

这在我的本地设置中给了Undefined Variable通知，这反过来阻止你调用header()，因为该通知被php计为输出。

Answer 3

在header（）调用之前有一个echo语句，这将导致发送标头。您不能在标题（）

之前输出任何内容

无法修改标头信息
