CollectionTrait
A collection is an immutable list of elements with a handful of functions to iterate, group, transform and extract information from it.
Table of Contents
Interfaces
- CollectionInterface
- Describes the methods a Collection should implement. A collection is an immutable list of elements exposing a number of traversing and extracting method for generating other collections.
- Serializable
Methods
- __construct() : mixed
- Constructor. You can provide an array or any traversable object
- __debugInfo() : array<string, mixed>
- Returns an array that can be used to describe the internal state of this object.
- __serialize() : array<string|int, mixed>
- Returns an array for serializing this of this object.
- __unserialize() : void
- Rebuilds the Collection instance.

- contains() : bool
