Yes, that would be an array in JSON. Please check http://www.json.org/ for the syntax. No bug here. (and yes, assoc arrays do end up as objects..)

Like this:

[jani@localhost ~]$ php -r 'var_dump(json_encode(array("foo" => "bar")));'
string(13) "{"foo":"bar"}"
[jani@localhost ~]$ php -r 'var_dump(json_encode(array("foo", "bar")));'
string(13) "["foo","bar"]"


No bug here.
