从另一个站点重定向后，如何获取上一页的URL？

Question

Is there any way to get the redirected site url? I am just curious about how to get the code of TinyUrl . Suppose I have created an url on tinyurl like http://ty.com/abcdef and this is to be redirected to my site like http://example.com/some-another-url . How do I get the code of tinyurl from http://example.com/some-another-url ?

** ty.com for tinyurl.com

Answer 1

You can use

$_SERVER['HTTP_REFERER'];

PS: This is unreliable as it may not work with secure pages (HTTPS)
