Internationalizing in Cakephp

Steps how to implement multiple language in Cake PHP

 Step 1: Set the route configuration in app/Config/routes.php               // i.e like www.google.com/language/controller/action
              Router::connect('/:language/:controller/:action/*',array(),array('language' => '[a-z]{3}'));

 Step 2: Set the config language in app/Config/core.php
            Configure::write('Config.language', 'eng');

 Step 3: create Helper in app/View/Helper/NewHtmlHelper.php
           App::uses('HtmlHelper', 'View/Helper');
           class NewHtmlHelper extends HtmlHelper {
                  public function url($url = null, $full = false) {
                  if(!isset($url['language']) && isset($this->params['language'])) {
                       $url['language'] = $this->params['language'];
                  }
                  return parent::url($url, $full);
           } 
 Step 4: Now change code in AppController app/Controller/AppController.php 
           class AppController extends Controller {
                   var $components = array('Session', 'Cookie');
                   public $helpers = array('Html' => array('className' => 'NewHtml'));
                   public function beforeFilter() {
                          $this->_setLanguage();
                      }

                private function _setLanguage() {
                       //if the cookie was previously set, and Config.language has not been set
                     //write the Config.language with the value from the Cookie
                    if($this->Cookie->read('lang') && !$this->Session->check('Config.language')) {
                             $this->Session->write('Config.language', $this->Cookie->read('lang'));
                          }else if ( isset($this->params['language']) && ($this->params['language'] !=        $this->Session->read('Config.language'))) {
        //then update the value in Session and the one in Cookie
            $this->Session->write('Config.language', $this->params['language']);
            $this->Cookie->write('lang', $this->params['language'], false, '20 days');
        }
    }

        //override redirect
        public function redirect( $url, $status = NULL, $exit = true ) {
            if (!isset($url['language']) && $this->Session->check('Config.language')) {
                $url['language'] = $this->Session->read('Config.language');
            }
            parent::redirect($url,$status,$exit);
        }
}  

Step 5: Now add the code in layout
        <?php    echo $this->Html->link('English', array('language' => 'eng'));
            echo $this->Html->link('France', array('language' => 'fra')); ?>

        Suppose you want to change following code
        <ul>
                <li><?php echo __('Send') ?></li>
                <li><?php echo __('Reply') ?></li>
                <li><?php echo __('Forward') ?></li>
               <li><?php echo __('Delete') ?></li>
   </ul>
Step 6: Make default.po file in Locale
           i.e app\Locale\eng\LC_MESSAGES\default.po
                  put code inside it
                 msgid "Send"
                 msgstr "Send"

                 msgid "Reply"
                 msgstr "Reply"

                msgid "Forward"
                msgstr "Forward"

                msgid "Delete"
                msgstr "Delete" 

            i.e app\Locale\fra\LC_MESSAGES\default.po
                 put code inside it
                msgid "Send"
                msgstr "Envoyer"

                msgid "Reply"
                msgstr "Réponse"

               msgid "Forward"
               msgstr "Vers l'avant"

               msgid "Delete"
               msgstr "Supprimer"

 Note: Where msgid is key and msgstr is value
