PHP Collections

, _(*1)

This library ports the Java Collections Framework to PHP., _(*2)

Installation

composer require tebru/php-collections

Collections

Collections provide data storage where order and random access do not matter. All collections implement CollectionInterface., _(*3)

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., _(*4)

Bag

This is an implementation of CollectionInterface that extends from AbstractCollection and uses an array as data storage., _(*5)

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., _(*6)

ArrayList

This is an implementation of CollectionInterface and ListInterface. It extends from AbstractList and uses an array as data storage., _(*7)

AbstractSet

This extends from AbstractCollection and implements SetInterface. Sets differ from generic collections by only allowing one of each element., _(*8)

HashSet

This is an implementation of CollectionInterface and SetInterface and extends from AbstractSet. This uses a HashMap as data storage., _(*9)

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., _(*10)

AbstractMap

This implements MapInterface and implements any methods that do not need to know about the specific data storage., _(*11)

HashMap

This is an implementation of MapInterface and extends from AbstractMap. It uses an array as data storage., _(*12)
