ChatGPT copied code:
Language Files: Keep language files in a separate directory for better organization.

Copy code
languages/
├── en.php
└── fr.php
Example content of en.php:

php
Copy code
<?php
return [
    'welcome_message' => 'Welcome to our website!',
    'about_us' => 'About Us',
    'contact_us' => 'Contact Us',
    // Add more key-value pairs as needed
];
Language Manager Class: Create a LanguageManager class to handle language loading and switching.

php
Copy code
<?php
class LanguageManager {
    private $language;

    public function __construct($langCode = 'en') {
        $langFilePath = 'languages/' . $langCode . '.php';
        if (file_exists($langFilePath)) {
            $this->language = include($langFilePath);
        } else {
            // Fallback to English if language file not found
            $this->language = include('languages/en.php');
        }
    }

    public function get($key) {
        return isset($this->language[$key]) ? $this->language[$key] : $key;
    }
}
Language Switching Logic: Implement language switching using sessions instead of cookies for better security and flexibility.

php
Copy code
<?php
session_start();

if (isset($_POST['language'])) {
    $_SESSION['preferred_language'] = $_POST['language'];
}

// Redirect back to the previous page
header('Location: ' . $_SERVER['HTTP_REFERER']);
exit;
HTML Interface: Create a language selector form.

html
Copy code
<form method="post" action="switch_language.php">
    <select name="language" onchange="this.form.submit()">
        <option value="en" <?php if($_SESSION['preferred_language'] == 'en') echo 'selected'; ?>>English</option>
        <option value="fr" <?php if($_SESSION['preferred_language'] == 'fr') echo 'selected'; ?>>French</option>
        <!-- Add more language options as needed -->
    </select>
</form>
Usage: Instantiate the LanguageManager and use it to display language-specific content.

php
Copy code
<?php
session_start();
include 'LanguageManager.php';

$langManager = new LanguageManager($_SESSION['preferred_language'] ?? 'en');

// Example usage
echo $langManager->get('welcome_message');
echo $langManager->get('about_us');
echo $langManager->get('contact_us');

This approach provides better separation of concerns and improves maintainability. It's also more secure by using sessions instead of cookies for language preferences. Additionally, it ensures a smoother user experience by avoiding unnecessary page reloads when switching languages.
