The collapse method collapses a collection of arrays into a flat collection:
.

2
3 $collapsed = $collection->collapse();
4
5 $collapsed->all();

7 // [1, 2, 3, 4, 5, 6, 7, 8, 9]
contains() {#collection-method}
The contains method determines whether the collection contains a given item:
.
1 $collection = collect(['name' => 'Desk', 'price' => 100]);
2
3 $collection->contains('Desk');
4
5 // true
6
7 $collection->contains('New York');
8
9 // false
You may also pass a key / value pair to the contains method, which will determine if the given pair
exists in the collection:
