In what scenarios is it recommended to use SSL for PHP websites beyond just member areas and admin sections?

Using SSL for PHP websites is recommended in scenarios where sensitive data is being transmitted, such as during the checkout process in an e-commerce site, when logging in or registering new users, or when submitting forms with personal information. SSL helps encrypt the data being sent between the user's browser and the server, ensuring that it cannot be intercepted by malicious actors. 

// Force SSL for specific pages in PHP
if($_SERVER['HTTPS'] != 'on'){
    $redirect_url = "https://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
    header("Location: $redirect_url");
    exit();
}
