PHP to JSON format
===

The JSON format I am getting is:
     
    {
        "test":[
            {"key1":"value1"},
            {"key2":"value2"}
         ]
    }

But is it possible to get this format instead?

    {
        "test": {
            "key1":"value1",
            "key2":"value2"
        }
    }

My php code is this:

    $key=$row[1];
    $value=$row[2];
    $posts[] = array($key => $value);
    
    $response['strings'] = $posts;
    fwrite($out, json_Encode($response))

I've been stuck on this for hours, someone please help! Thanks in advance!
