Yii Message Translator

This package allows translating messages into several languages. It can work with both Yii-based applications and standalone PHP applications.

Requirements

• PHP 8.0 or higher.

Installation

The package could be installed with Composer:

Additional packages

There are two types of additional packages. Message source provide support of various message storage formats such as PHP arrays or GNU gettext. Message formatters provide extra syntax that is recognized in translated messages.

Message sources

• translator-message-php - PHP file message storage.
• translator-message-db - Database message storage.
• translator-message-gettext - gettext message storage.

Built-in message formatters

• Simple formatter just replaces parameters in messages. Does not take into account the locale.
• intl formatter utilizes PHP intl extension message formatting capabilities.

Extracting messages

The message extraction is done via console extractor that searches for translator message calls and builds translation files.

In some cases you need to do so without using console. If that is your case, check extractor guide.

Configuration

Quick start

First, get a configured instance of event dispatcher. When using a framework it is usually done as:

Configuration depends on the container used so below we'll create an instance manually.

$fallbackLocale and $eventDispatcher are optional. Fallback locale is used when no translation was found in the main locale. Event dispatcher is used to dispatch missing translation events.

Now we've got an instance, but it has no idea where to get translations from. Let's tell it:

That's it. Translator is ready to be used.

Advanced configuration for Yii3 application

After installing the package, you will get the following configuration files in your application config:

• config/packages/yiisoft/translator/common.php
• config/packages/yiisoft/translator/params.php

You need get implementation of MessageReader and MessageSource to complete configuration. See "Additional packages", "Message sources" above.

The following configuration is for Yii3 application after all needed packages installed:

You need uncomment strings around ApplicationCategorySource in common.php and params.php files:

and params.php:

Multiple translation sources

Adding many category sources at once

Overriding translation messages

If you use a module that has message translation and want to redefine default translation messages, you can add your category source with the same categoryName as used in the module.

During translation CategorySources are used from last to first allowing overriding messages of the same category and ID.

General usage

Using default language and default category

Specifying category and language

Change default locale

Get a current locale, if you don't know set locale

Get a new Translator instance with a locale to be used by default in case locale isn't specified explicitly

Get a new Translator instance with a category to be used by default in case category isn't specified explicitly

Additional info

The package contains interfaces for development of custom formatters, readers, and writers.
