README

A trait to implement the Multiton design pattern without any dependencies.

Installation

$ composer require michaelspiss/multiton

Basic Usage

One line is enough to turn a class (called DatabaseAccess only for demonstration purposes) into a multiton:

<?php

class DatabaseAccess {
    
    use MichaelSpiss\DesignPatterns\Multiton;
    
    ...
}

To retrieve the multiton instance, simply call ::getInstance() with a unique identifier:

$instance = DatabaseAccess::getInstance('ID');

Another instance can be retrieved by doing the exact same with another ID.

During initialization the constructor is called with the identifier as argument. You can change the __construct() method as you wish, as long as it only requires the identifier as attribute and it's visibility is protected, to prevent instantiations via the new operator.

PHP Requirements

• PHP >= 5.4
