按索引对stdClass对象排序

Question

I've seen a million similar questions on stackoverflow but none of them, that I can find, deal with sorting the actual index value of the object.

I have a standard object that I've given a value ($vid) to sort instead of it populating incrementally itself.

foreach ($array_videos as $v) {
            $govideo = $this->staff_model->get_video($v->vid);
            $goforit[$v->vid] = $vimeo->call('vimeo.videos.getInfo', array('video_id' => $govideo->video_id));
}

When I do this I receive the following output:

[33] => stdClass Object ...
[12] => stdClass Object ...
[55] => stdClass Object ...
[61] => stdClass Object ...

I would like to sort this array of objects by the object index, ASC or DESC. For example:

[61] => stdClass Object ...
[55] => stdClass Object ...
[33] => stdClass Object ...
[12] => stdClass Object ...

I've tried ksort and some various usort functions. Can't seem to wrap my head around this.

Any help would be appreciated.

Answer 1

ksort() will do the trick:

ksort($array_videos);

ksort will sort the array keys in ASC . you could quickly reverse the order using array_reverse() :

$array_videos = array_reverse($array_videos);

for your real world example you could do one of the following:

foreach (ksort($array_videos) as $v)

or

foreach (array_reverse(ksort($array_videos)) as $v)

Better Yet!! to reverse the sort to DESC as per the recommendations by Jim , you can use krsort() :

ksort($array_videos); //ASC
krsort($array_videos); //DESC
