Question

Answer 1

请参阅 PHP Get Current URL :

Sometimes it is not as straightforward as one may think to get the current url to use it inside your application. Here is a snippet that I use to fetch the current URL and use it in a script. The current url (whether http or https) is now a local variable that you can do with as you please.

$url = "http".(!empty($_SERVER['HTTPS'])?"s":"").
"://".$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'];

Note: You should groom this value before using in anything sensitive, like a sql query.
