[Phpsniff-devel] Browser HTTP_ACCEPT_LANGUAGE

[Dave G. <php...@gu...>]

Hi,

This is my first email to this list (in fact it may be the first email
_ever_ to this list!) so hello to Roger Raymond (epsilon7 @ SF) and
hello to everyone else! I am aware of the forums at

http://sourceforge.net/projects/phpsniff/

but I _much_ prefer email to the small textarea boxes on the forums :-)

Firstly let me introduce myself. My name is Dave Guerin (daveguerin @
SF) and I am one of the developers of the web content management system
called Pagetool

http://www.pagetool.org/

http://sourceforge.net/projects/pagetool

We currently use phpSniff in the generation of a browser specific style
sheet for a Pagetool site. Thank you very much for all your work on the
class Roger!

We have attempted to make Pagetool multi lingual, include()ing specific
language files depending on the HTTP_ACCEPT_LANGUAGE set by the browser.
Currently we use the following function to return the name of the file
to be included:

function pt_accept_language()
{
 global $ptconf, $HTTP_ACCEPT_LANGUAGE;
 /*
 $lang set to the default value of 'en'. If no other language is
 available this language file will be returned.
*/
 $lang =3D 'en';
 if (isset($HTTP_ACCEPT_LANGUAGE))
 {
  if
(file_exists("src/lang/pt_lang_".substr($HTTP_ACCEPT_LANGUAGE,0,2).".inc"
))
  {
   $lang =3D substr($HTTP_ACCEPT_LANGUAGE,0,2);
  }
 }
 return("src/lang/pt_lang_". $lang . ".inc");
}

This works fine for the first preferred language the user has set.
However if the HTTP_ACCEPT_LANGUAGE is

nn-no,es-pr;q=3D0.8,sv;q=3D0.7,zh-hk;q=3D0.5,en;q=3D0.3,en-gb;q=3D0.2

for example (that's Norwegian (Nynorsk), Spanish (Puerto Rico), Swedish,
Chinese (Hong Kong SAR), English, and English (United Kingdom) and no I
don't speak all of those) then English is included as the default
language, and then Norwegian will be included if it exists. If it
doesn't exists, that's it. Even if Spanish is available the user will
only get English :-(

Also, another problem is the various values returned by different
browsers:

IE6 SP1     Norwegian (Nynorsk) nn-no
            Norwegian (Bokm=E5l)  no
            Norwegian (Bokm=E5l)  nb-no

Opera 6.01  Norwegian (Nynorsk) no-nyn
            Norwegian (Nynorsk) nn
            Norwegian (Bokm=E5l)  nb
            Norwegian (Bokm=E5l)  no-bok
            Norwegian           no

Mozilla 1.0 Norwegian (Nynorsk) nn
            Norwegian           no
            Norwegian (Bokm=E5l)  nb

And no I don't speak any form of Norwegian, a Pagetool user contributed
a language file in Norwegian (Nynorsk) and I was at a loss as to how to
deal with it. It's not as easy as a plain old English language
include().


I know phpSniff has a

$client->language_is(language)

function but this doesn't deal with the variation in browser values for
the same language, or with the addition of dialects to a basic language
like en-gb or en-us.

I was wondering if phpSniff was to be extended in any way to assist in
dealing with these problems. I more than willing to help in any way I
can with coding but I'm not sure currently quite which way is the best
way forward.

I look forward to any comments and ideas people on this list may have.
