# CakePHP Collection Library
|
||
|
|
|
||
|
|
The collection classes provide a set of tools to manipulate arrays or Traversable objects.
|
||
|
|
If you have ever used underscore.js, you have an idea of what you can expect from the collection classes.
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
Collections can be created using an array or Traversable object. A simple use of a Collection would be:
|
||
|
|
|
||
|
|
```php
|
||
|
|
use Cake\Collection\Collection;
|
||
|
|
|
||
|
|
$items = ['a' => 1, 'b' => 2, 'c' => 3];
|
||
|
|
$collection = new Collection($items);
|
||
|
|
|
||
|
|
// Create a new collection containing elements
|
||
|
|
// with a value greater than one.
|
||
|
|
$overOne = $collection->filter(function ($value, $key, $iterator) {
|
||
|
|
return $value > 1;
|
||
|
|
});
|
||
|
|
```
|
||
|
|
|
||
|
|
The `Collection\CollectionTrait` allows you to integrate collection-like features into any Traversable object
|
||
|
|
you have in your application as well.
