It worth to note that if $langtag array is empty this function returns empty string and not $default . Use array(false) if your $langtag array is empty in order to get default locale.

Note that this method does not understand "similar" languages, so the following:

    Locale::lookup(["en-US"], "en-GB", false);
Or:
    Locale::lookup(["es-ES"], "es-CO", false);

Does not work as you would expect (empty result). To get a match in those cases you will have to use two letter language codes instead:

    Locale::lookup(["en"], "en-GB", false);
Or:
    Locale::lookup(["es"], "es-CO", false);

These do return 'en' and 'es' respectively.
