Get full URL

Mandakins

I want to set the current page url as a variable but can't find anywhere how to get the URL in the first place.

Can I get the URL using php? It's got to be something so simple that no one has posted about it and I'm just missing it somehow.

Thanks.

You could try this...

$url = "http://{$_SERVER['HTTP_HOST']}{$_SERVER['REQUEST_URI']}";

That will work in most cases:

a) Not all web servers provide REQUEST_URI, annoyingly (Apache typically does though)
b) The above code will of course get the URL wrong if it's being served via HTTPS - it should really check $SERVER['HTTPS'] too
c) It will also fail if $SERVER['HTTP_HOST'] is not set. However, this is usually set, and is actually a requirement for HTTP 1.1 and using name-based virtual hosts.

So what is the most viable solution? What are other solutions for this?

If you can guarantee that you're going to be running on Apache or a server which provides REQUEST_URI, you can use that (as above).

If you know you're not going to be on HTTPS, you don't need to bother checking that.

If REQUEST_URI is absent, the whole URL can be figured out by a combination of:

SCRIPT_NAME
PATH_INFO
QUERY_STRING

(I think)

Some of the above may be wrong though. REQUEST_URI bundles it all up nicely.

Also if you're doing rewriting, REQUEST_URI appears to give the original one, whereas SCRIPT_NAME gives the modified name.
