Installation

composer require tebru/php-collections

Collections

Collections provide data storage where order and random access do not matter. All collections implement CollectionInterface.

AbstractCollection

This is an abstract class that implements the methods it can. It defers the decision of what underlying data structure to use to the concrete implementation.

Bag

This is an implementation of CollectionInterface that extends from AbstractCollection and uses an array as data storage.

AbstractList

This inherits from AbstractCollection and implements the ListInterface. Lists add random access to collections. The allow getting/setting/removing at a specific index. By default, they add elements to the end of the list.

ArrayList

This is an implementation of CollectionInterface and ListInterface. It extends from AbstractList and uses an array as data storage.

AbstractSet

This extends from AbstractCollection and implements SetInterface. Sets differ from generic collections by only allowing one of each element.

HashSet

This is an implementation of CollectionInterface and SetInterface and extends from AbstractSet. This uses a HashMap as data storage.

Maps

Maps provide data storage where order does not matter, but the ability to get a value by key is important. All maps implement MapInterface.

AbstractMap

This implements MapInterface and implements any methods that do not need to know about the specific data storage.

HashMap

This is an implementation of MapInterface and extends from AbstractMap. It uses an array as data storage.
