PHP Sorting Objects

Question

    [sections] => stdClass Object
            (
                [22353] => stdClass Object
                    (
                        [id] => 2
                        [section_start_date] => 1410235200
                    )

                [22354] => stdClass Object
                    (
                        [id] => 1
                        [section_start_date] => 1410235260

                    )
)

How do I sort the above objects in PHP by the id, while preserving the keys of the sections object? For instance I want to show 22354 on top of 22353. Since these are objects the keys are technically just strings to me but I need to keep them in tact.

There is some confusion going on. These are objects which are not in an array. Pay close attention to the section object.

These are objects which are not in a collection like an array. — allencoded, Aug 25 '15 at 22:39
you are right but does not make sense ordering object properties ... IMHO i see it like a bad design — daremachine, Aug 25 '15 at 22:51

this is how you do it

stdClass Object
(
    [111111] => stdClass Object
        (
           [id] => 2
           [section_start_date] => 1410235200
       )
    [999999] => stdClass Object
       (
            [id] => 1
            [section_start_date] => 1410235260
       )

    [222222] => stdClass Object
        (
            [id] => 1
            [section_start_date] => 1410235300
    )
    [555555] => stdClass Object
        (
            [id] => 1
            [section_start_date] => 1410231160
        )
)

Steps Convert stdClass to array

$data = json_decode(json_encode($object),true);
ksort($data);
print_r($data);

output new sorted array while maintaining key index.

Array
(
    [111111] => Array
        (
            [id] => 2
            [section_start_date] => 1410235200
        )
    [222222] => Array
        (
            [id] => 1
            [section_start_date] => 1410235300
        )
    [555555] => Array
        (
            [id] => 1
            [section_start_date] => 1410231160
        )
    [999999] => Array
        (
           [id] => 1
           [section_start_date] => 1410235260
        )
)
