How do you remove duplicates from a collection in Laravel?
Answer: In Laravel, you can remove duplicates from a collection using the `unique()` method. For example:
“`php
$collection = collect([1, 2, 2, 3, 4, 4, 5]);
$uniqueCollection = $collection->unique();
“`
This will result in a new collection that contains only unique values: `[1, 2, 3, 4, 5]`. You can also chain the `values()` method to reindex the collection if needed:
“`php
$uniqueCollection = $collection->unique()->values();
“`
