gordon: I still think this is a bit excessive. Perhaps instead of
valid_url() we could use a simpler regexp !^[a-z]://!i or even

This little patch allows full URLs to be used for the url() and l()
functions, giving modules a single interface for creating links. 
Currently, modules must use l() for drupal links and raw HTML for
external links.  This patch changes url() to handle -- basically pass
through -- full URLs while still doing the proper handling of internal
paths and works with clean URLs enabled or disabled.  It also shortens
(and hopefully simplifies) the url() code a bit.

Some examples of calls that now work:

l('a link', 'some/path');  // same as before
l('an external link', 'http://drupal.org/');
l('full with query', 'http://google.com/search?q=define:foo');
l('full with separate query', 'http://google.com/search', array(),
'q=define:foo'); // same link as above
l('full with fragment', 'http://drupal.org/node/5942#comment-12374');
l('full with separate fragment', 'http://drupal.org/node/5942',
array(), NULL, 'comment-12374'); // same link as above

+1. less HTML in code is a good thing for readability, if nothing else.

Revisiting this issue one year later shows we're almost there. The only
thing that's left is the ability to handle external urls when
clean_urls is disabled.  Once implemented, menu.module can happily
accept external urls and not just Drupal paths, making the menu system
much more attractive to end users.

I'll update the menu.module docs if this patch (or an alternative
solution) is accepted.

+1 This is a good thing for people who can't using clean urls.

This patch seems like a good idea, but does not apply anymore.  Also,
shouldn't the comments for l() and url() be updated to indicate that
the functions will work with both internal and external URL's?

The &'s had been changed to & amp; , here's a valid patch

This is a  new patch against cvs that allows url() to create external
links, with the side-effect that menu can now be used to make external
Also closes http://drupal.org/node/10177

This will be even more important with the primary links menu
integration. (This patch already cleans up a special case in
phptemplate for that).

Killes benchmarked this, and it turns out the difference is negligible.
Requests per second:    1.33 [#/sec] (mean) = with patch
Requests per second:    1.31 [#/sec] (mean) = without patch.

I had benchmarked /node as anon user without cache.

+1 on the idea of this patch. It allows people to use l() for external

However, I don't like the implementation. Running that complicated
regexp for every url() call is simply wasteful. 95% or more of url()
calls have a fixed string as parameter and point to Drupal's own paths.

I suggest we create an url_external() wrapper around url() which allows
external URLs. Any path which we want to allow external URLs in can use
url_external() instead. The places where we use it will not be many

splitting into url() url_external is not a good idea. The main reason
for this patch that I see is for putting external urls into the
navigation menu using the menu.module, and if all goes to plan, the
primary and secondary menus.
