The sorted collection keeps the original array keys. In this example we used the values method to
reset the keys to consecutively numbered indexes.
You can also pass your own callback to determine how to sort the collection values:
1 $collection = collect([
2 ['name' => 'Desk', 'colors' => ['Black', 'Mahogany']],
3 ['name' => 'Chair', 'colors' => ['Black']],
4 ['name' => 'Bookcase', 'colors' => ['Red', 'Beige', 'Brown']],
5 ]);
6
7 $sorted = $collection->sortBy(function ($product, $key) {
8 return count($product['colors']);
9 });
10
11 $sorted->values()->all();
12
13 /*
14 [
15 ['name' => 'Chair', 'colors' => ['Black']],
16 ['name' => 'Desk', 'colors' => ['Black', 'Mahogany']],
17 ['name' => 'Bookcase', 'colors' => ['Red', 'Beige', 'Brown']],
