hi tim,

the code is basicly a class for manipulating languages in php.
feel free to edit and use this code:

Code: Select all

<?php
class lang {
/**

*/

var $code = null;
var $langs = array('en' =>"English",'es'=>"Spanish",'fr'=>"French",'zh'=>"Chinese");
   
   function __construct($lang = ''){
      $this->code = $this->auto_lang($lang);
      $this->load_lang_tags();
   }

   public function is_language($lang = 'en'){
      return array_key_exists($lang, $this->langs);
   }

   private function browser_lang(){
      $lang = substr($_SERVER['HTTP_ACCEPT_LANGUAGE'], 0, 2);
      $lang = (isset($lang) && $lang != "") ? $lang : "en"; //handles empty values by spiders
      return ($this->is_language($lang)) ? $lang : 'en';
   }
   
   public function auto_lang($lang=''){
      if ((empty($lang)) || !($this->is_language($lang))){
         $code = $this->browser_lang();
         $code = (isset($code))? $code : "en";
      } else {
         $code = $lang;
      }
      return $code;
   }
   
   public function get_code(){
      return $this->code;
      }
   
}

?>
