PHP-JSON Translator – A Simple Multi-Language Solution

This PHP Translator allows you to easily implement multi-language support in your web projects using JSON-based translation files. It automatically detects the user's preferred language and provides CSRF protection for language changes.

Requirements: PHP Sessions

How It Works:

1. The user's preferred language is detected via HTTP_ACCEPT_LANGUAGE.
2. If no language is set, it defaults to English (en).
3. Translations are stored in a translation.json file.
4. A CSRF token is generated to prevent unauthorized language changes.
5. The Translator class fetches the correct translation based on the user's selected language.

Example form for the language settings and the CSFR-Token:

<form method="POST">
     <input type="hidden" name="pcstvalueLV" value="<?php echo $_SESSION['pcstLV']; ?>">
    <select name="language">
        <option value="en">English</option>
        <option value="de">Deutsch</option>
    </select>
    <button type="submit">Change Language</button>
</form>

Possible changes and extensions

-> Add more languages by updating translation.json. -> Implement AJAX for smoother language switching. -> Store user preferences in a database instead of $_SESSION.
