How can you ensure that the language selection remains consistent throughout navigation on a bilingual website in PHP?

To ensure that the language selection remains consistent throughout navigation on a bilingual website in PHP, you can store the selected language in a session variable. This way, the language choice will persist as the user navigates through different pages of the website. 

// Start or resume a session
session_start();

// Check if a language selection has been made
if(isset($_GET['lang'])){
    // Set the selected language in a session variable
    $_SESSION['lang'] = $_GET['lang'];
}

// Default language selection
if(!isset($_SESSION['lang'])){
    $_SESSION['lang'] = 'en'; // Default language is English
}

// Include language files based on the selected language
include 'languages/'.$_SESSION['lang'].'.php';
