我有一个在Localhost上工作正常的PHP联系表（将电子邮件发送到我的收件箱并将其重定向到另一页）。但是，当我将其上传到Liveerver并进行测试时，用户输入将提交给我的电子邮件收件箱，但在浏览器上显示输入，并且不会重定向到另一个页面（谢谢您的页面）。我正在使用phpmailer类发送表格。

错误消息
Warning: Cannot modify header information - headers already sent by (output started at /home4/pwebken/public_html/PHPMailer/class.smtp.php:234) in /home4/pwebken/public_html/contact.php on line 157
您始终可以使用 headers_sent（）进行探测，如果仍然可以...发送标头。这对于有条件打印任何信息或应用后备逻辑很有用。
if (headers_sent()) {
die(file_get_contents("thank_you.php"));
}
else{
exit(header("Location: /user.php"));
}
而不是使用标题header('Location:thank_you.php');
使用echo '<script>location.replace("thank_you.php");</script>';
希望它有帮助！
