Yii: GetText _() vs Yii::t()

Question

When translating strings in Yii with GetText, do we have to use Yii::t($category,\'message\') or gettext\'s _(\'message\') syntax?

And then how

Answer 1

I use it like this:

when i have for example:

Yii::app()->language = en

in folder messages have I folder en and on this folder I have file lang.php

on this folder lang.php I have for example:

'search',
        'example2'=>'news',
    );

then when i need call view translate:

and result is: search

---

when I change: Yii::app()->language = de, I must have messages/de/lang.php and on this foler I have:

'Suche',
        'example2'=>'Nachrichten',
    );

then when i need call view translate:

result is: Suche
