PHP - Get URL and remove the trailing slash

Question

So I've created this function that get's the URL of the Website, but I also want it to remove the trailing / as well.

So far I have this:

function base_url() {
    $base_url = $_SERVER['HTTPS'] == 'on' ? 'https' : 'http';

    return $base_url.'://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
}

But I don't know how to remove the trailing / from the URL.

I've also tried to add the rtrim but still no luck:

function base_url() {
    $base_url = $_SERVER['HTTPS'] == 'on' ? 'https' : 'http';
    $base_url = rtrim($base_url, '/');

    return $base_url.'://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
}

Try it like this:

function base_url() {
    $base_url = $_SERVER['HTTPS'] == 'on' ? 'https' : 'http';
    $base_url.= '://'.$_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];

    return rtrim( $base_url, '/' );
}
