I need to return a PHP array to Jquery, with the following format:

```
{
  labels: [1, 2, 3],
  series: [
    [
      {meta: 'description', value: 1},
    ],
  ]
}

```

How can I do this? I tried a few ways, and the one I came closest to is an index inserted in the path.

```
$return = array(
                 "labels" => [1,2,3],
                  "series" => [
                        array(
                            "meta" => ['description'],
                            "value" => [1],

                        ),
                    ],  

                );

```
