麻烦转换php数组到json格式有点错误

Question

I'm having trouble getting the correct json format from the following php array

Array
(
    [0] => Array
        (
            [name] => name1
            [data] => Array
                (
                    [0] => Array
                        (
                            [5] => 2013-15-6,9
                            [6] => 2013-15-7,9
                            [7] => 2013-15-8,9
                            [8] => 2013-15-9,9
                            [9] => 2013-15-10,9
                            [10] => 2013-15-11,9
                            [11] => 2013-15-12,9
                        )

                )

        )

)

Encoding it to json outputs

[
    {
        "name": "name1",
        "data": [
            {
                "5": "2013-15-6,9",
                "6": "2013-15-7,9",
                "7": "2013-15-8,9",
                "8": "2013-15-9,9",
                "9": "2013-15-10,9",
                "10": "2013-15-11,9",
                "11": "2013-15-12,9"
            }
        ]
    }
]

What I need the json output to look like is below, basically removing the curly brackets inside the data array and remove the index numbers thought I don't think that's possible.

[
    {
        "name": "name1",
        "data": [
            "2013-15-11,9",
            "2013-15-12,9"
        ]
    }
]

I've tried different combinations of array() around variables which got me close enough by adding the bracket inside the data array but I can't get rid of the curly brackets. Would really appreciate some help, have been working on this for a few hours. Thanks

I took the json output that you are expecting to get and did json_decode on it, that's the result:

Array
(
    [0] => stdClass Object
        (
           [name] => name1
           [data] => Array
                (
                    [0] => 2013-15-11,9
                    [1] => 2013-15-12,9
                )

        )

)

So that's how your PHP structure should look like before sending it to json_encode.

P.S. I checked it with json_encode (reversed the process) and it returns exactly what you need.
