forPage() {#collection-method}
The forPage method returns a new collection containing the items that would be present on a given
page number:
.
1 $collection = collect([1, 2, 3, 4, 5, 6, 7, 8, 9])->forPage(2, 3);
2
3 $collection->all();

5 // [4, 5, 6]
The method requires the page number and the number of items to show per page, respectively.
get() {#collection-method}
The get method returns the item at a given key. If the key does not exist, null is returned:
.
1 $collection = collect(['name' => 'taylor', 'framework' => 'laravel']);
2
3 $value = $collection->get('name');
4
5 // taylor
You may optionally pass a default value as the second argument:
.
1 $collection = collect(['name' => 'taylor', 'framework' => 'laravel']);
2
3 $value = $collection->get('foo', 'default-value');
4
5 // default-value
