Are there best practices for implementing language selection scripts in PHP to ensure a smooth user experience?

To ensure a smooth user experience when implementing language selection scripts in PHP, it is recommended to use a session variable to store the selected language preference. This allows the user's language choice to persist across different pages of the website. Additionally, make sure to provide clear language options for the user to choose from and utilize language files to store translations for different languages. 

<?php
session_start();

// Check if language selection form is submitted
if(isset($_POST['lang'])) {
    $_SESSION['lang'] = $_POST['lang'];
}

// Include language file based on user's selection
if(isset($_SESSION['lang'])) {
    include 'languages/'.$_SESSION['lang'].'.php';
} else {
    include 'languages/english.php'; // Default language
}

// Example language file (english.php)
$lang['welcome_message'] = 'Welcome to our website!';

// Display translated text
echo $lang['welcome_message'];
?>
