Language Detection

The following different strategies are used to detect the language.

• by Accept-Language-Header (e.g. 'de-CH,en;q=0.8,en-US;q=0.5,fr;q=0.3')
• by Cookie (e.g Cookie 'lang', value 'en')
• by UriPath (e.g. /shop/en/article/3453452)
• by QueryParam (e.g. index.php?lang=en)

These methods can be chained independently after each other. The last method that detects an available language wins. If no language can be detected, the default language will be returned.

Installation

Use composer:

composer require unicate/language-detection

Usage

<?php

require_once "vendor/autoload.php";

// Available Languages: First entry is assumed to be the default language.
$availableLang = ['en', 'de', 'fr'];

// All methods chained. The last method that detects a language wins.
$langDetection = new \Unicate\LanguageDetection\LanguageDetection($availableLang);
$lang = $langDetection->byHeader()->byCookie()->byUri()->byParam()->getLang();

// Only by Param ?lang=en
$langDetection = new \Unicate\LanguageDetection\LanguageDetection($availableLang);
$lang = $langDetection->byParam()->getLang();

// Only by Uri /shop/en/article/3453452
$langDetection = new \Unicate\LanguageDetection\LanguageDetection($availableLang);
$lang = $langDetection->byUri()->getLang();
