Location and Refresh both require an absolute URI(and it's "Location" instead of "location").
Location 和 Refresh 都需要绝对 URI（它是“Location”而不是“location”）。
Try this one:
试试这个：
header('Location: http://absolute.uri/file.ext');
If that does not help, check my answer for any "strange" PHP problem;)
如果这没有帮助，请检查我的答案是否有任何“奇怪的”PHP 问题；)

Depends on what you are trying to do. Are you trying to cause a redirect ? If this is the case you could simply use header('Location: http://www.example.com/');but if you want to refresh after a certain amount of time you can use:
取决于你想做什么。你想引起重定向吗？如果是这种情况，您可以简单地使用，但如果您想在一定时间后刷新，则可以使用：header('Location: http://www.example.com/');
header( "refresh:5;url=wherever.php" );
echo 'You\'ll be redirected in about 5 secs. ';
echo 'If not, click <a href="wherever.php">here</a>.';
Got the example code from - http://php.net/manual/en/function.header.php- maybe worth a read too.
从 - http://php.net/manual/en/function.header.php获取示例代码- 也许也值得一读。

(1) you don't need the refresh header if you have the location one
(1) 如果您有位置一，则不需要刷新标头
(2) add exit;in the end
(2)exit;在最后添加
The second special case is the "Location:" header. Not only does it send this header back to the browser, but it also returns a REDIRECT (302) status code to the browser unless the 201 or a 3xx status code has already been set.
第二个特殊情况是“Location:”标题。它不仅会将此标头发送回浏览器，而且还会向浏览器返回 REDIRECT (302) 状态代码，除非已经设置了 201 或 3xx 状态代码。
<?php
header("Location: http://www.example.com/"); /* Redirect browser */
/* Make sure that code below does not get executed when we redirect. */
exit;
?>

Then better use JavaScript for that. Append this code before :
那么最好为此使用 JavaScript。在此之前附加此代码：
<script> setTimeout(function() { window.location = "index.php"; }, 2000); </script>
