Collections 288
1 collect([1, 2, 3, 4, 5])->avg();
2
3 // 3
If the collection contains nested arrays or objects, you should pass a key to use for determining
which values to calculate the average:
1 $collection = collect([
2 ['name' => 'JavaScript: The Good Parts', 'pages' => 176],
3 ['name' => 'JavaScript: The Definitive Guide', 'pages' => 1096],
4 ]);
5
6 $collection->avg('pages');
7
8 // 636
chunk() {#collection-method}
The chunk method breaks the collection into multiple, smaller collections of a given size:
1 $collection = collect([1, 2, 3, 4, 5, 6, 7]);
2
3 $chunks = $collection->chunk(4);
4
5 $chunks->toArray();
6
7 // [[1, 2, 3, 4], [5, 6, 7]]
This method is especially useful in views when working with a grid system such as Bootstrap¹⁶⁶.
Imagine you have a collection of Eloquent models you want to display in a grid:
