i found a very good Bundle that handles all this stuff automagically:

Answer 5

Symfony2.3, in Twig, try this to get uri:

{{ dump(app.request.server.get("REQUEST_URI")) }}

Answer 6

This is how I do it (using Symfony 2.6)

<li {% if app.request.get('_route') == '_homepage' %} class="active" {% endif %}><a href="{{ path('_homepage') }}">Student</a></li>

'_homepage' is the name of route in routing.yml of your bundle and the route looks like this

_homepage:
    path:     /
    defaults: { _controller: CoreBundle:Default:index }
