Your browser treats the response as plaintext.
您的浏览器将响应视为纯文本。
Prepend to you response a Content-Type: text/html\n plus wrap your content inside an <html></html>tag.
预先为您响应Content-Type: text/html\n 加上将您的内容包装在<html></html>标签中。

Why not just use output bufferingand not have to deal with JavaScript or meta redirects at all?
为什么不直接使用输出缓冲而不用处理 JavaScript 或元重定向呢？
<?php
// Top of your page
ob_start();
// Code goes here
// Redirect
if ($redirect_is_necessary)
{
header('Location: '.$url);
exit;
}
// Rest of page goes here
// Bottom of page
ob_end_flush();
?>
