_route() function for SlimPHP 3.4.2, it returns the path for the named route

helper.route.php

<?php

if( ! function_exists('_route'))
{
    /**
     * Return the path for the named route
     *
     * @see http://www.slimframework.com/docs/objects/router.html#route-names
     * @param  string $name
     * @param  array  $parameters
     * @return mixed
     */
    function _route($name = '', $parameters = [])
    {
        global $app;

        if($app instanceof Slim\App)
            return $app->getContainer()
                       ->get('router')
                       ->pathFor($name, $parameters);

        return FALSE;
    }
}

If in routes.php there is a route named fruit.index, like in this example:

$app->get('/fruit/{name}', '\App\Controllers\FruitController:index')->setName('fruit.index');

And in the view we want to print the path:

echo _route('fruit.index', ['name' => 'fuji_apples']);

The result will be /fruit/fuji_apples.
