This article summarizes how to sort the order of a collection in Laravel.

Laravel Framework 8.83.8
Vue 2.6

Conclusion

// Assuming you have a collection like this.
$posts = Post::all();
// Sort
$sorted = $posts->sortBy('created_at');
// Remove keys
$sorted->values()->all();

Explanation

In this example, let's try changing the order of a collection that was obtained from the Posts table.

Ascending order of created_at

$sorted = $posts->sortBy('created_at');

In this state, you will see by using dd() that keys are present, making it difficult to simply use it in a foreach loop.

It seems like keys are associated with the collection before sorting. Currently, the purpose of using these keys is unclear, so let's move on to the next point.

Remove keys and make it easier to use with the following code

$sorted->values()->all();

By using this code, the keys are removed, and the collection is now in a more user-friendly state.

When you want to sort the collection in descending order

$sorted = $posts->sortByDesc()('created_at');

Summary

That's all.

I hope this can be useful for someone.
