How to use Yii::t () for text information translation and file translation in Yii framework

1. Set the localized language

In the Protected/config folder under the main.php, do the following settings:

Return Array (    ' BasePath ' =>dirname (__file__). Directory_separator. '. ',    ' name ' = ' My Web application ', ' sourcelanguage ' = '    en_us ',    ' language ' = > ' ZH_CN ',

2. Define translation files

Here I use the PHP file to achieve text information translation (more ways to refer to the Yii Framework Official Guide Series 48--topic: Internationalization (i18n)), through this method to achieve translation before the protected/ Messages Create a folder named Localid (in this case, ZH_CN), and then create a custom PHP file under the folder (not named Yii, because the name can only be used internally by the YII framework), in this case we create a app.php:

Return Array (    ' my web application ' = ' my web site ', ' home ' = '    homepage ',    ' about ' + ' on ',    ' contact ' = > ' Contact us ',    ' login ' = ' sign in ',    ' Logout ' + ' exit ', ';

3. Using translations

Calling the method is simple, just by using the built-in Yii::t () method call:

Yii::t (' app ', ' My Web application ')

For example, we can translate the website title and navigation bar in protected/views/layouts/main.php:

<div id= "header" >    <div id= "logo" ><?php Echo chtml::encode (yii::t (' app ', Yii::app ()->name));? ></div></div><!--Header--><div id= "MainMenu" >    <?php $this->widget (' Zii.widgets.CMenu ', Array (        ' Items ' =>array ('            label ' =>yii::t (' app ', ' Home '), ' url ' =>array ('/ Site/index '),            Array (' label ' =>yii::t (' app ', ' about '), ' url ' =>array ('/site/page ', ' view ' = ' about '),            Array (' label ' =>yii::t (' app ', ' contact '), ' url ' =>array ('/site/contact ')),            Array (' label ' =>yii::t (' app ', ' Login '), ' url ' =>array ('/site/login '), ' Visible ' =>yii::app ()->user->isguest),            Array (' Label ' =>yii::t ' (' app ', ' Logout '). ' (‘. Yii::app ()->user->name. ', ' url ' =>array ('/site/logout '), ' visible ' =>! Yii::app ()->user->isguest))     ;?></div><!--MainMenu--

4. View File translation

For example, if we want to implement site/index.php view file translation, we need to first create the ZH_CN folder under the Protected/views/site folder, and then copy site/index.php to the site/zh_cn/folder. Then translate the index.php folder under the Zh_cn folder:

<?php    /* @var $this Sitecontroller *    /$this->pagetitle=yii::t ("app", Yii::app ()->name);? >
At this point, we simply completed the translation of the Site/index page, previewed as follows:

Passing parameters
Definitions in the PHP translation source:
# protected/messages/zh_cn/app.php<?php    return Array (        //other stuff.        ' The username {username} is not available. ' = ' user name {username} is invalid. ',        //More other stuff.    );
Invoke the implementation translation statement:
Echo yii::t (' app ', ' the username {username} is not available. ', Array (' {username} ' = $username));
Working with complex numbers
For example, if we deal with such translations:
Echo yii::t (' app ', ' The item has been added to your cart.| The {n} items have a been added to your cart. ', $num);
The code in the corresponding app.php is as follows:
# protected/messages/es_mx/app.php<?php    return Array (        ' n==1#the item have been added to your cart.| n>1#the Items has been added to your cart. ' +            ' is already in your shopping cart. | Everything has been put in your shopping cart. ',    );
