PHP - Detect the incoming url requesting php page from another source/url
提问by Simon Davies
Is there a way in which I can detect the URL that is calling in my php page, similar to say a GET or POST but would like to get the URL as I would like to restrict the page accessing it to a certain URL as this file is being called from another server.
有没有一种方法可以检测在我的 php 页面中调用的 URL，类似于 GET 或 POST 但想要获取 URL，因为我想将访问它的页面限制为某个 URL 作为这个文件正在从另一台服务器调用。
Basically: www.MYURL.com calls the php file from say www.PHPURL.com if the URL is NOT www.MYURL.com then bounce them out etc.
基本上：如果 URL 不是 www.MYURL.com，www.MYURL.com 会从 www.PHPURL.com 调用 php 文件，然后将它们弹出等。
Many Thanks
非常感谢
In response to the answers below I used the as mentioend and here is what I did:
为了回应下面的答案，我使用了 as mentioend，这是我所做的：
$URL_REF = parse_url($_SERVER['HTTP_REFERER']);
$URL_REF_HOST = $URL_REF['host'];
Thanks @Philip Bevan,@Itai Sagi and @EvilP

well, you could use $_SERVER['HTTP_REFERER']- but it can be cloaked/removed.
好吧，你可以使用$_SERVER['HTTP_REFERER']- 但它可以被隐藏/移除。
EDIT: as someone asked, the HTTP_REFERER is a header which is sent by the client, most browsers default behavior is to send it, but if you'd like, you can disable it or even send a different referer header so people will think you come from some place else.
编辑：正如有人问的，HTTP_REFERER 是由客户端发送的标头，大多数浏览器的默认行为是发送它，但如果您愿意，您可以禁用它甚至发送不同的引用标头，以便人们会认为您来自其他地方。
the bottom line: if it isn't THAT critical for you, you can use it, but don't EVER, EVER give people extra privileges based on their referer alone.
底线：如果它对您来说不是那么重要，您可以使用它，但永远不要仅根据他们的推荐人给予人们额外的特权。

$_SERVER["HTTP_REFERER"]
is what you are looking for.
就是你要找的。
