HTTP header

@riversideJun 24.2006

Hi to all of you.

I have a multilingual php website (en, de, cz). Each language I keep in separate .php file which I include into script when user change language (from icon). But I would like to make my script more clever, and exactly when user from UK access to my page, the script show the text in english language; the same for other supporting languages. I heard before that this is possible if I watch into HTTP header return by Apache webserver(Accept-Language) ???? If anyone of you know more about this please help me, I’ll be appreciate.

Thanks

@NogDogJun 24.2006 — #You could do something like:

[code=php]
 <?php
 if(isset($_COOKIE['language']))  // see if you already have preference
 {
 $language = $_COOKIE['language'];
 }
 elseif(!empty($_SERVER['HTTP_ACCEPT_LANGUAGE']))  // use http header if there
 {
 $language = strtolower(array_shift(explode('-',
 $_SERVER['HTTP_ACCEPT_LANGUAGE'])));
 }
 else  // otherwise set to default
 {
 $language = 'en';  // change to whatever default language is desired
 }
 switch($language)
 {
 case 'en':
 // display in English
 break;
 case 'de':
 // display in German
 break;
 case 'fr':
 // display in French
 break;
 default:
 // display in default language
 }
 ?>
 [/code]

@bokehJun 24.2006 — #Nogdog's approach is good but but needs to include cookie setting. The following is something I wrote ages ago for [URL=http://costablancatranslations.com/]this site[/URL]. It runs the whole string and if more than one of available languages is contained in the accept language header it will choose the one that appears earlier in the string (which is the correct behaviour).

[code=php]<?php
 
 function language()
 {
 # function returns longhand form of the language.
 # function expects longhand form of the language in the 
 # $_GET variable to switch languages (?language=english) 
 
  // Set variables
  $default_language = 'english';
  $supported_languages = array(
   'en' => 'english',
   'cz' => 'czech',
   'de' => 'german'
  );
 
  // Client is setting language with query string '?language=english 
  if((!empty($_GET['language'])) and (in_array($_GET['language'], $supported_languages)))
  {
   setcookie ('language', $_GET['language'], time()+100000000, '/', '', 0);
   return $_GET['language'];
  }
 
  // Check for preset language in $_COOKIE['language']
  if((!empty($_COOKIE['language'])) and (in_array($_COOKIE['language'], $supported_languages)))
  {
   return $_COOKIE['language'];
  }
 
  // If none of the above the script finds the first
  // matching browser language or returns the language
  // in the $default_language variable on no match
  if(empty($_SERVER['HTTP_ACCEPT_LANGUAGE']))
  {
   return $default_language;
  }
  $bar = ''; # to use in regex pattern
  foreach($supported_languages as $k => $v){
   $pattern .= $bar.$k;
   $bar = '|';
  }
  if(preg_match('/'.$pattern.'/', $_SERVER['HTTP_ACCEPT_LANGUAGE'], $matches))
  {
   return $supported_languages[$matches['0']];
  }
  return $default_language;
 }
 
 #test it
 echo '<p>Currently active language: <span style="color:#f00">'. language() .'</span></p>';
 
 
 ?>
 
 <p><a href="<?php echo $_SERVER['PHP_SELF']?>?language=english">english</a></p>
 <p><a href="<?php echo $_SERVER['PHP_SELF']?>?language=german">german</a></p>
 <p><a href="<?php echo $_SERVER['PHP_SELF']?>?language=czech">czech</a></p>
 <p>After changing language delete the query string and refresh. Notice your choice sticks.</p>[/code]

I've got the time - I just keep falling asleep when I try to read my Java books. :rolleyes:
