Introduction

SlmLocale is a Laminas module to automatically detect a locale for your application. It uses a variety of pluggable strategies to search for a valid locale. SlmLocale features a default locale, a set of supported locales and locale aliases.

SlmLocale supports out of the box several strategies to search for a locale. Through interfaces, other strategies could be created. The set of default stragies is:

The HTTP Accept-Language header
A cookie to store the locale between several sessions of one visitor
A query parameter to easily switch from locale
The first segment of the path of an uri
A part of the domain name (either the TLD or a subdomain)

Furthermore, it provides a set of additional localisation features:

A default locale, used as fallback
A set of aliases, so you can map .com as "en-US" in the host name strategy
Redirect to the right domain/path when a locale is found
View helpers to create a localised uri or a list of language switches

Installation

Add "slm/locale" to your composer.json file and update your dependencies. Enable SlmLocale in your application.config.php.

If you do not have a composer.json file in the root of your project, copy the contents below and put that into a file called composer.json and save it in the root of your project:

{
    "require": {
        "slm/locale": ">=0.1.0,<1.2.0-dev"
    }
}

Then execute the following commands in a CLI:

curl -s http://getcomposer.org/installer | php
php composer.phar install

Now you should have a vendor directory, including a slm/locale. In your bootstrap code, make sure you include the vendor/autoload.php file to properly load the SlmLocale module.

Usage

Set your default locale in the configuration:

'slm_locale' => [
    'default' => 'nl-NL',
],

Set all your supported locales in the configuration:

'slm_locale' => [
    'supported' => ['en-US', 'en-GB'],
],

And enable some strategies. The naming is made via the following list:

cookie: SlmLocale\Strategy\CookieStrategy
host: SlmLocale\Strategy\HostStrategy
acceptlanguage: SlmLocale\Strategy\HttpAcceptLanguageStrategy
query: SlmLocale\Strategy\QueryStrategy
uripath: SlmLocale\Strategy\UriPathStrategy
asset: SlmLocale\Strategy\AssetStrategy

You can enable one or more of them in the strategies list. Mind the priority is important! You usually want the acceptlanguage as last for a fallback:

'slm_locale' => [
    'strategies' => ['uripath', 'acceptlanguage'],
],

At this moment, the locale should be detected. The locale is stored inside php's Locale object. Retrieve the locale with Locale::getDefault(). This is also automated inside Laminas translator objects and i18n view helpers (so you do not need to set the locale yourself there).

Set the locale's language in html

It is common to provide the html with the used locale. This can be set for example in the html tag:

<html lang="en">

Inject the detected language here with the following code:

<html lang="<?= $this->primaryLanguage()?>">

Disable UriPathStrategy in PHPUNIT

This is necessary (at the moment) if you want to use this->dispatch('my/uri'); in your AbstractHttpControllerTestCase unit tests. Otherwise, if you check for responseCode you will get 302 where it should be 200.

Example:

$this->dispatch('/to/my/uri');
$this->assertResponseStatusCode(200); // this will be 302 instead of 200

$this->dispatch('/en/to/my/uri');
$this->assertResponseStatusCode(200); // this will be 302 instead of 200

To fix add the following to your phpunit config.

phpunit.xml:

<phpunit...>
    ...
    <php>
        <server name="DISABLE_URIPATHSTRATEGY" value="true" />
    </php>
</phpunit>

Or set $_SERVER['DISABLE_URIPATHSTRATEGY'] = true; in your bootstrap file of phpunit.

Create a list of available locales

slm/locale 适用场景与选型建议

slm/locale 是一款基于 PHP 开发的 Composer 扩展包，目前已累计 284.45k 次下载、GitHub Stars 达 68，最近一次更新时间为 2012 年 08 月 20 日，在 PHP 生态内属于活跃度较高的组件。

它主要适用于以下技术方向：「i18n」「locale」「Zend Framework」「zf」「laminas」等业务场景。在实际项目中，围绕这些方向常见需要落地的问题包括：接口对接、性能调优、并发安全、与既有框架（Laravel / ThinkPHP / Yii / Webman 等）的兼容适配，以及生产环境的日志埋点与稳定性保障。

我们在过去多个企业项目中使用过 slm/locale 或与其功能相近的方案，如果你在选型或落地过程中遇到问题，例如 版本兼容、二次改造、私有化封装、与内部系统对接、生产 BUG 排查，欢迎联系我们协助评估。

围绕 slm/locale 我们能提供哪些服务？
