Added information that expands on Seb's answer.

php > print json_encode( array( 'a', 'b', 'c' ) ) ;
["a","b","c"]
php > print json_encode( array( 0 => 'a',  1 => 'b', 2 => 'c' ) ) ;
["a","b","c"]
php > print json_encode( array( 1 => 'a',  2 => 'b', 3 => 'c' ) ) ;
{"1":"a","2":"b","3":"c"}
php > 

Note: its formatting it this way with good cause:

If you were to send

{"1":"a","2":"b","3":"c"}

as

["a","b","c"]

When you did $data[1] in Php you would get back "a", but on the JavaScript side, you would get back "b" .
