将新数组值添加到现有数组位置

I have array which is presenting like this:

        $array = array (
        "list" => array(
            "serwer-1" => 3
        ),
        "servers" => array(
            3 => array(
                "msg" => "{'some data': 123123121313}",
                "status" => 200
            ),
        ),
    );

I want add new items to $array['list'] for example:

        array (
        "list" => array(
            "serwer-1" => 3
            //NEW DATA HERE
            "serwer-2" => 7,
        ),
        "servers" => array(
            3 => array(
                "msg" => "{'some data': 123123121313}",
                "status" => 200
            ),
        ),
    );

Maybe it's trivial, but I haven't any idea how to do this - I have bad day today :(

In order to add a key-value pair to an existing array just do it like the key exists there.

$array["list"]["serwer-2"] = 7;

Then you will get desired result.
