این متد هنگام کار با Viewها بسیار کاربردی میباشد، در مثال زیر Productها را به آرایههای ۳ تایی تقسیم کردیم و سپس نمایش دادیم.
@foreach ($products->chunk(3) as $chunk)
<div class="row">
@foreach ($chunk as $product)
<div class="col-xs-4">{{ $product->name }}</div>
@endforeach
</div>
@endforeach
$collection = collect([[1, 2, 3], [4, 5, 6], [7, 8, 9]]);

$collectionA = collect([1, 2, 3]);
$collectionB = $collectionA->collect();
$collectionB->all();
// [1, 2, 3]
$collection = collect(['name', 'age']);
$combined = $collection->combine(['George', 29]);
$combined->all();
// ['name' => 'George', 'age' => 29]
$collection = collect(['John Doe']);
$concatenated = $collection->concat(['Jane Doe'])->concat(['name' => 'Johnny Doe']);
$concatenated->all();
// ['John Doe', 'Jane Doe', 'Johnny Doe']
$collection = collect(['name' => 'Desk', 'price' => 100]);
$collection->contains('Desk');
// true
$collection->contains('New York');
// false
همچنین میتوانیم چک کنیم که آیا یک Key و Value بهطور همزمان در یک آرایه وجود دارند یا خیر.
$collection = collect([
['product' => 'Desk', 'price' => 200],
['product' => 'Chair', 'price' => 100],

اگر میخواهید که ادامهی کد متوقف نشود، میتوانید بهجای dd از dump استفاده کنید.
The dump method dumps the collection's items:
$collection = collect(['John Doe', 'Jane Doe']);
$collection->dump();
/*

#items: array:2 [
0 => "John Doe"
1 => "Jane Doe"
]

اگر بخواهیم در یک یا چند آرایه، بین Keyهای خاص، دنبال مقادیری بگردیم که ۲ بار تکرار شدهاند، به شکل زیر عمل میکنیم.
$employees = collect([
['email' => 'abigail@example.com', 'position' => 'Developer'],
['email' => 'james@example.com', 'position' => 'Designer'],
['email' => 'victoria@example.com', 'position' => 'Developer'],

بهطور مثال در کد بالا اولين دادهای که نامش Linda است را دریافت میکنیم.
$collection->firstWhere('age', '>=', 18);
// ['name' => 'Diego', 'age' => 23]
یا در این مثال اولين دادهای که سنش بزرگتر مساوی ۱۸ باشد را دریافت میکنیم.
