Bug description:json_decode skips value where json_encode includes it

Description:
------------
If you have empty array inside object, json_encode() does encode the value
into JSON format, but when the data is decoded with json_decode(), this
empty JSON array is omitted from output.

Consider following structure:

 ["timetable"]=>
  object(pizzaonline\model\Timetable)#30 (9) {
    ["id"]=>
    string(3) "774"
    ["timetable"]=>
    array(0) {
    }
    ["opening_hours"]=>
    ..

Corresponding json_encode would be:

"timetable":{
    "id":"774",
    "timetable":[

    ],
    "opening_hours":[
  ..

This is all right, but I have a loop that removes this empty array with
unset(). So PHP structure from JSON is encoded is like:

["timetable"]=>
  object(pizzaonline\model\Timetable)#30 (8) {
    ["id"]=>
    string(3) "774"
    ["opening_hours"]=>

But using json_encode() returns same result that is in snippet 2.

Just ask if any questions, I’ll do example script later...
