Singleton

A trait to implement the Singleton design pattern without any dependencies., _(*1)

, _(*2)

Why?

There already are plenty other singleton packages, so why another one? Simply, because most of those packages implement a factory, rather than a singleton pattern. This and many more things bothered me about them, so here is a simple, dependency-free and fully tested singleton., _(*3)

Installation

$ composer require michaelspiss/singleton

Basic Usage

One line is enough to turn a class into a singleton:, _(*4)

<?php

class StorageProvider {

    use MichaelSpiss\DesignPatterns\Singleton;

    ...
}

To retrieve the singleton instance, simply call, _(*5)

$singleton = StorageProvider::getInstance();
