Why www.wikipedia.org => en.wikipedia.org ? - Wikitech-l

6 Jan 2005

Saluton [English version follows],

Mi volas scii kial la adreso http://www.wikipedia.org kondukas automate 
al la adreso http://en.wikipedia.org... Chu Wikipedia estas angla 
projekto kun tradukoj, au chu ghi vere estas internacia? Oni povas uzi 
tiun PHP programon por solvi tiun problemon :

function handle_http_accept_language() {
   $knownlangs = array( "eo", "fr", "en" ); # Etc
   $lang = "eo"; # Default
   $lastquality = 0.0;

   # Note HTTP reference RFC 2616 -
   # ftp://ftp.isi.edu/in-notes/rfc2616.txt

   $langtag = '((?:[a-zA-Z]{1,8})(?:-[a-zA-Z]{1,8})*)';
   $qvalue ='(0(?:\.[0-9]{1,3})?|1(?:\.0{1,3}))';
   $eachbit = '^' . $langtag . '(?:;q=' . $qvalue .
')?(?:,\s*)?(.*)$';

   $alh = trim( $_SERVER["HTTP_ACCEPT_LANGUAGE"] );

   while(strlen($alh)) {
     if( preg_match( "/$eachbit/", $alh, $m ) ) {
       $tag = $m[1];
       $quality = $m[2];
       if(strlen($quality) == 0) $quality = 1;
       $alh = $m[3];

       #echo "language '$tag' quality '$quality'\n";

       if(in_array($tag, $knownlangs) and $quality > $lastquality) {
         $lang = $tag;
         $lastquality = $quality;
       }
     } else {
       break;
     }
   }
   return $lang;
}

Mi ne subskribis al la listo, char estas mia nura propono. :-)

Dankon,
Grégoire

Hello,

I want to know why the address http://www.wikipedia.org redirects 
automatically to http://en.wikipedia.org... Is Wikipedia an english 
project with translations, or is it a real international project? We can 
use this PHP program to solve this problem :

function handle_http_accept_language() {
   $knownlangs = array( "eo", "fr", "en" ); # Etc
   $lang = "eo"; # Default
   $lastquality = 0.0;

   # Note HTTP reference RFC 2616 -
   # ftp://ftp.isi.edu/in-notes/rfc2616.txt

   $langtag = '((?:[a-zA-Z]{1,8})(?:-[a-zA-Z]{1,8})*)';
   $qvalue ='(0(?:\.[0-9]{1,3})?|1(?:\.0{1,3}))';
   $eachbit = '^' . $langtag . '(?:;q=' . $qvalue .
')?(?:,\s*)?(.*)$';

   $alh = trim( $_SERVER["HTTP_ACCEPT_LANGUAGE"] );

   while(strlen($alh)) {
     if( preg_match( "/$eachbit/", $alh, $m ) ) {
       $tag = $m[1];
       $quality = $m[2];
       if(strlen($quality) == 0) $quality = 1;
       $alh = $m[3];

       #echo "language '$tag' quality '$quality'\n";

       if(in_array($tag, $knownlangs) and $quality > $lastquality) {
         $lang = $tag;
         $lastquality = $quality;
       }
     } else {
       break;
     }
   }
   return $lang;
}

I did not subscribe to the list, because this is my only proposition.

Thank you,
Grégoire
