What are the potential drawbacks of relying solely on .htaccess for language changes in PHP?

Relying solely on .htaccess for language changes in PHP can be limiting because it only affects the URL structure and not the actual content of the website. To fully implement language changes, it's better to use a combination of .htaccess for URL rewriting and PHP for dynamically changing the content based on the language selection.

// Example of dynamically changing content based on language selection in PHP

$language = isset($_GET['lang']) ? $_GET['lang'] : 'en';

if($language == 'en'){
    // English content
    echo "Hello, welcome to our website!";
} elseif($language == 'fr'){
    // French content
    echo "Bonjour, bienvenue sur notre site web!";
} else {
    // Default content
    echo "Hello, welcome to our website!";
}
