In PHP arrays elements may have custom keys:

PHP Code:

array("Color" => "Yellow", "Size" => "S") 


In JavaScript (JSON comes from there) arrays have no keys, so arrays with keys translate from PHP to JSON as objects:

{"Color":"Yellow", "Size":"S"}

There is nothing wrong in doing that and you won't get any benefits by wrapping the object into an extra array (that will always contain a single element only).
