How do you use the `intersect` method in Laravel collections?

Answer: In Laravel, you use the `intersect` method on a collection to return a new collection containing only the items that are present in both the original collection and the given array or collection. Here’s an example:

“`php
$collection1 = collect([1, 2, 3, 4]);
$collection2 = collect([3, 4, 5, 6]);

$intersected = $collection1->intersect($collection2);
// $intersected will contain [3, 4]
“`

This method preserves the keys from the original collection.
