PHP Language Translator / Localizer

Outputs translated text based on current language settings.
Text strings are stored in PHP files and these can be stored in subfolders for better maintaining.

Features:

• Translate keys into text values based on set language.
• Support for string replacement with parameters.
• Handle different translations based on a counter value.
• Easy to structure localization texts in a clean folder hierarchy.

Installation

To install the library, use Composer:

composer require wufr/php-language-localizer

Note: This library requires PHP version 8.0 or higher.

Quick Start

Here is a quick example to get you started:

require_once "./vendor/autoload.php";

use wUFr\Translator;

$translator = new Translator(dir: "./locales/", lang: "en_US");
echo $translator->locale("someFolder/testValues", "translateThis");
// outputs "translated value"

Files Structure Example

Example folder structure:
You can specify custom location for the "locales" folder, if you need to.

/locales/
    en_US/
        someFolder/
            testValues.php
            ...

    cs_CZ/
        ...
    ...
/vendor/
    ... (composer packages)
...
composer.json
index.php

Example localization file:
Path to this file and name of the file itself is used in the locale() method. This way you can structure your localization texts in a nice clean structure with folders for different parts of the website, like "eshop", "user-area", "admin-panel" etc.

en_us/someFolder/testValues.php:

$l = [
    "translateThis" => "translated value",
    "BasedOnNumber" => [
        1  => "box",
        2  => "boxes",
        50 => "a lot of boxes"
    ],
    "thxText" => "Thank you {username} for buying {product}",
    "thxTextCounter" => [
        1 =>   "Thank you {username} for buying a piece of {product}",
        2 =>   "Thank you {username} for buying two of {product}",
        50 =>  "Thank you {username} for buying {count} pieces of {product}",
    ],
];

Usage

Simple String

echo $translator->locale("someFolder/testValues", "translateThis");
// outputs "translated value"

String Based on "Amount" of Something

echo $translator->locale("someFolder/testValues", "BasedOnNumber", ["_counter" => 1]);
// outputs "box"

echo $translator->locale("someFolder/testValues", "BasedOnNumber", ["_counter" => 50]);
// outputs "a lot of boxes"

String with Replaceable Values

echo $translator->locale("someFolder/testValues", "thxText", [
    "username" => "John Doe",
    "product"  => "AMD Epyc Server"
]);
// outputs "Thank you John Doe for buying AMD Epyc Server"

Combined with Counter

echo $translator->locale("someFolder/testValues", "thxTextCounter", [
    "_counter" => 50,
    "count"    => 50,
    "username" => "John Doe",
    "product"  => "AMD Epyc Server"
]);
// outputs: "Thank you John Doe for buying 50 pieces of AMD Epyc Server"

Important: the _counter parameter is used only to decide which string is returned, not as a variable inside string. You need to add (in this case) count in the parameters.
