register_nav_menus syntax error, unexpected identifier “register_nav_menus” in

Question

In theme functions.php you just check this… I think it’s may help you

In demo_menus function I use your code it works pretty well… I don’t tell my code is good but I think this is best practice, we should try to best practice.

function demo_menus(){
    $locations = array(
        'top-menu' => __( 'Top Menu Location', 'text-domain' ),
        'mobile-menu' => __( 'Mobile Menu Location', 'text-domain' )
    );
    register_nav_menus( $locations );
}
add_action( 'after_setup_theme', 'demo_menus' );

This is my localhost output
