@tomi what's the difference between unique() and values()? they seem to do the same.

Unique removes duplicated items ... check the example in documentation
$collection = collect([
['name' => 'iPhone 6', 'brand' => 'Apple', 'type' => 'phone'],
['name' => 'iPhone 5', 'brand' => 'Apple', 'type' => 'phone'], // <-- this is removed because duplicated brand
['name' => 'Apple Watch', 'brand' => 'Apple', 'type' => 'watch'], // <-- this is removed because duplicated brand
['name' => 'Galaxy S6', 'brand' => 'Samsung', 'type' => 'phone'],
['name' => 'Galaxy Gear', 'brand' => 'Samsung', 'type' => 'watch'], // <-- this is removed because duplicated brand
]);
$unique = $collection->unique('brand');
$unique->values()->all();
/*
[
['name' => 'iPhone 6', 'brand' => 'Apple', 'type' => 'phone'],
['name' => 'Galaxy S6', 'brand' => 'Samsung', 'type' => 'phone'],
]
*/
