Twig create link with variable

Question

I would like to create a link to another page in my plugin and send a specific ID with it but I don't really know how to do it in craft and twig.. I spend too much time on that little task and searched in the internet but could not really find something.

In my template I have

//loop through all database entries
{% for val in entries %}
    .....
    <a href="{{ url('pluginName/editEntry/' + val.id) }}">Edit</a>
    .....
{% endfor %}

But it does not really work. How can I pass a specific id in my url and how can I receive this parameter in my php backend? I didn't find something like craft()->request->getGetVar()and my $_GET is always empty. Of course I could just take the URL and use subtring and explode to get the correct value but I'm not sure if this is the intended way

Use the ~ symbol to concat strings.

//loop through all database entries
{% for val in entries %}
    .....
    <a href="{{ url('pluginName/editEntry/' ~ val.id) }}">Edit</a>
    .....
{% endfor %}
