I'd like to know how I should implement this code, to filter URLs for members and non-members? Should I put the code into the functions.php file?

$user = wp_get_current_user();
if( $user->exists ) {
    add_filter( 'public_link_root', function() { return 'example'; });
}

// Whenever you have to output a link, instead of doing that check over and over, because it's already established that the user's logged in, if you wrote your system in the correct manner (and you can do additional checks), do:

$link_to_output = apply_filters( 'public_link_root', 'ourwebsite' ) . '/resources/whatever/here';

You will want to add the hook function in your functions.php file:

$user = wp_get_current_user();
if($user->exists) {
    add_filter('public_link_root', function() { return 'example'; } );
}

Then whenever you are working with a URL in any of your template files, you can allow the URL to be modified by your customer filter public_link_root. The filter will only run if the user exists, otherwise the URL won't be altered.

So in your template files:

$some_link = apply_filters('public_link_root', 'ourwebsite') . '/resources';
echo '<a href="' . $some_link . '">View Resources</a>';

For this to make more sense, you should spend some time reading the documentation and example code on add_filter and apply_filters.
