Introduction
The Illuminate\Support\Collection class
provides a fluent, convenient wrapper for working with
arrays of data. For example, check out the following
code. We'll use the collect helper to
create a new collection instance from the array:
$collection = collect(['taylor', 'abigail', null])->map(function($name)
{
return strtoupper($name);
})
->reject(function($name)
{
return is_null($value);
});
As you can see, the Collection class allows
you to chain its methods to perform fluent mapping and
reducing of the underlying array. In general, every
Collection method returns an entirely new
Collection instance. To dig in further,

Basic Usage
Creating Collections
As mentioned above, the collect helper will
return a new Illuminate\Support\Collection
instance for the given array. You may also use the
make command on the Collection
class:
$collection = collect([1, 2, 3]);
$collection = Collection::make([1, 2, 3]);
Of course, collections of Eloquent objects
are always returned as Collection
instances; however, you should feel free to use the
Collection class wherever it is convenient
for your application.
