Getting Started

Usage

Just create a config object once and call the load function in your PHP Script.

You can also view the example here.

index.php:

<?php
//get default config or set it manually
$config = Config::getDefaults();
$resource = new Resource($config);
echo $resource->loadString("sample_text");
?>

/dictionary/default.xml:

<?xml version="1.0" encoding="utf-8" ?>
<resources>

    <!-- Header -->
    <string id="sample_text">This is a sample text in english</string>

</resources>

/dictionary/german.xml:

<?xml version="1.0" encoding="utf-8" ?>
<resources>

    <!-- Header -->
    <string id="sample_text">Das ist ein deutscher Beispieltext</string>

</resources>

Configuration

Edit config values if needed:

const	default value	description
DOCUMENT_ROOT	dirname(__DIR__) . DIRECTORY_SEPARATOR	Path to document root
PATH_TO_DICTIONARIES	DOCUMENT_ROOT . DIRECTORY_SEPARATOR . 'dictionary' . DIRECTORY_SEPARATOR	Path to dictionary folder. Folder contains all XML files
DEFAULT_LANGUAGE	en	Default language in ISO 639-1 format. The constant will be used, if language cannot be determined
DEFAULT_DICTIONARY	default.xml	This XML file will be used, if other files are not available. This file should contain all string items.
LANGUAGE_DETECTION	cookie	This defines the method to detect the language. Choose between 'header', 'cookie' and 'rewrite'.
COOKIE_NAME	language	Default key for the cookie.
SUPPORTED_LANGUAGES	array(DEFAULT_LANGUAGE => DEFAULT_DICTIONARY)	Contains all supported languages. Example: "de" => "german.xml",

Example:

<?php
$config = Config::getDefaults();
$config->set(Config::DOCUMENT_ROOT, "/");
?>

Language detection methods

header

This will try to read $_SERVER['HTTP_ACCEPT_LANGUAGE']. If this fails, DEFAULT_LANGUAGE will be returned.

cookie

This will try to read a cookie with the key COOKIE_NAME. If no cookie is set, it will use the header method and set the new cookie.

rewrite

This will try to read $_SERVER['REQUEST_URI'] and split it to identify the language. If no argument is set, it will use the header method
You can use a URL structure like example.com/en/index.php

Details

• The used language format is ISO 639-1. For more information see https://en.wikipedia.org/wiki/ISO_639-1
• If the requested string is not available in the XML file, the script will try to search in the DEFAULT_DICTIONARY (default.xml) file. An empty string will be returned if nothing matches.
