 New Comment:

Docs are wrong, it should be:

echo Locale::lookup($languages, 'en_US', false, 'en_UK');

But there's also a bug in lookup, will fix it.

Description:
------------
The documentation says that the return value of Locale::lookup is "The
closest matching language tag or default value.", but the matching tag
is modified.

The result of the example below doesn't match the searched (en_US) nor
the matched (en-us) tag, but is totally different (en_us).

Reproduce code:
---------------
<?php

$languages = array("en", "en-us");
echo Locale::lookup($languages, 'en_US', 'en_UK');

?>

Expected result:
----------------
en-us

Actual result:
--------------
en_us
