The sorted collection keeps the original array keys. In this example we used the values method to
reset the keys to consecutively numbered indexes.
For sorting a collection of nested arrays or objects, see the sortBy and sortByDesc methods.
If your sorting needs are more advanced, you may pass a callback to sort with your own algorithm.
Refer to the PHP documentation on usort¹³⁸, which is what the collection’s sort method calls under
the hood.
sortBy() {#collection-method}
The sortBy method sorts the collection by the given key:
.
1 $collection = collect([
2 ['name' => 'Desk', 'price' => 200],
3 ['name' => 'Chair', 'price' => 100],
4 ['name' => 'Bookcase', 'price' => 150],
5 ]);
6
7 $sorted = $collection->sortBy('price');
8
9 $sorted->values()->all();

11 /*
12 [
13 ['name' => 'Chair', 'price' => 100],
14 ['name' => 'Bookcase', 'price' => 150],
15 ['name' => 'Desk', 'price' => 200],
16 ]
