Unable to use json response properly

Im using datatables to show data and I want to fetch language settings from my server in a nice way. The problem is to format the data in a way that makes this possible, I would prefer to use json format with as few modifications as possible.

I want to use this:

(as an argument for my datatable creation, what is this? array? object? json string?)

var oLanguage =    
{ 
    "oLanguage": {
        "sLengthMenu": "_MENU_ per page"
    }
};

I try to obtain this data from the server using this method:

$.getJSON( '/olan', function(data){
    oLanguage=data;
});

SERVER CODE: (PHP, SLIM)

$app->get('/olan', function() use ($app, $lan){
    $oLanguage = array('oLanguage' => array('sLengthMenu' => '_MENU_ per page'));
    $response = $app->response();
    $response['Content-Type'] = 'application/json';
    $response->body(json_encode($oLanguage));
});

I was able to iterate through the data in the $.getJSON method and all information is there, must be something with the format/object handling. I don't yet have a good understanding of the type of object that i need, i can declare it, but i don't know what it is:) I hope its some kind of json object so i can just easily get it as i try to do. I could maybe declare it using $.each iteration but it would be ugly.

This is my first question here on stackoverflow, thank you for helping me out

-------------------------Answer (cannot post it the first 8 hours)---------------

Turns out,

thanks to Shinosha

, that there is a build in feature of datatables to get the language settings from server. By creating the table like this:

$('#tableid').dataTable({
    "oLanguage": {
                "sUrl": "/olan"
        }
});

and editing my server code: (changing the $oLanguage variable)

$app->get('/olan', function() use ($app, $lan){
    $oLanguage = array('sLengthMenu' => '_MENU_ per page');
    $response = $app->response();
    $response['Content-Type'] = 'application/json';
    $response->body(json_encode($oLanguage));
});

It works!

In Javascript, [] denotes array and {} denotes object. You can nest objects and arrays as required. Use a json validator like jsonlint.com to validate your server response. , gvmani

oLanguage is an object with the attribute oLanguage which is an object with the attribute sLengthMenu. sLengthMenu have the value "MENU per page"

var oLanguage =    
{ 
    "oLanguage": {
        "sLengthMenu": "_MENU_ per page"
    }
};
