How can PHP be used to dynamically switch between language files on a website?

To dynamically switch between language files on a website using PHP, you can store language strings in separate files for each language (e.g., en.php for English, fr.php for French). Then, based on user input or preferences, you can include the appropriate language file to display content in the desired language. 

<?php
// Get user's selected language (e.g., from a dropdown menu or session)
$selectedLanguage = isset($_GET['lang']) ? $_GET['lang'] : 'en'; // Default to English if no language is selected

// Include the corresponding language file
include_once "languages/{$selectedLanguage}.php";

// Usage example: echo a language string
echo $lang['welcome_message']; // Output: Hello, welcome to our website!
?>
