不使用密钥创建PHP对象？

Question

I've got a request to present the data in the following format as a JSON feed:

{
    "id": "123",
    "info": {
        "code": "ZGE",
        "description": "test1",
        "type": "AVL",
        "date": "09/08/2012"
    }
},
{
   "id": "456",
    "info": {
        "code": "ZDN",
        "description": "test2",
        "type": "CLR",
        "date": "16/02/2012"
    }
}

However in my PHP code, I think I need to have a key itterator - but I end up with this format:

{

"0": {
    "id": "123",
    "info": {
        "code": "ZGE",
        "description": "test1",
        "type": "AVL",
        "date": "09/08/2012"
    }
},
"1": {

    "id": "456",
    "info": {
        "code": "ZDN",
        "description": "test2",
        "type": "CLR",
        "date": "16/02/2012"
    }
}
}

Any ideas on how to build the first data set with out having the index iterator?

Answer 1

It can be built like this:

$arr = array(
    array(
        'id' => 123,
        'info' => array(
            'code' => 'ZGE',
            'description' => 'test1',
            'type' => 'AVL'
        )
    ),
    array(
        'id' => 456,
        'info' => array(
            'code' => 'ZDN',
            'description' => 'test2',
            'type' => 'CLR'
        )
    )
);

echo json_encode($arr);

Outputs

[
    {
        "id": 123,
        "info": {
            "code": "ZGE",
            "description": "test1",
            "type": "AVL"
        }
    },
    {
        "id": 456,
        "info": {
            "code": "ZDN",
            "description": "test2",
            "type": "CLR"
        }
    }
]
