Answer 1

set configuration variables at runtime

class AppServiceProvider extends ServiceProvider
{
    /**
    * Bootstrap any application services.
    *
    * @return void
    */
    public function boot()
    {
        View::share('key', 'value');
        Schema::defaultStringLength(191);

        $company=DB::table('company')->where('id',1)->first();
        // View::share('company',$company);  
        config(['yourconfig.company' => $company]);
    }
}

usage:

config('yourconfig.company');
