Fibonacci php classes implementation as singleton, strategy and adapter design patterns, _(*1)

, _(*2)

Installation

The recommended way to install bundle is through Composer:, _(*3)

$ composer require sharkzt/fibonacci

Usage Examples

Singleton

``` php //get fibonacci series via class with recursion approach $fibonacciWithRecursion = new \Sharkzt\Fibonacci\Singleton\Fibonacci(11); return $fibonacciWithRecursion->getSeries();, <sub>(*4)</sub>

//get fibonacci series via class with iteration approach $fibonacciWithIteration = new \Sharkzt\Fibonacci\Singleton\FibonacciIterator(11); $fibonacciWithIteration->initialize(); return $fibonacciWithIteration->getSeries();, <sub>(*5)</sub>

Code above will return [0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55].

### Adapter

``` php
//get fibonacci series via iterator adapter
$fibonacciIteratorAdapter = new FibonacciIteratorAdapter(new FibonacciIterator());
$fibonacciIteratorAdapter
    ->setCount(11)
    ->initialize();

return $fibonacciIteratorAdapter->getSeries();

//get fibonacci series via recursion adapter
$fibonacciIteratorAdapter = new FibonacciRecursionAdapter(new Fibonacci());
$fibonacciIteratorAdapter
    ->setCount(11)
    ->initialize();

return $fibonacciIteratorAdapter->getSeries();

This will return [0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55]., <sub>(*6)</sub>

Strategy

``` php //get fibonacci series with iteration strategy $fibonacciStrategy = new FibonacciStrategy(new Fibonacci(), new FibonacciIterator()); $fibonacciStrategy->setStrategy($fibonacciStrategy->iterationStrategy); $fibonacciStrategy ->setCount(11) ->initialize();, <sub>(*7)</sub>

return $fibonacciStrategy->getSeries();, <sub>(*8)</sub>

//get fibonacci series with recursion strategy $fibonacciStrategy = new FibonacciStrategy(new Fibonacci(), new FibonacciIterator()); $fibonacciStrategy->setStrategy($fibonacciStrategy->recursionStrategy); $fibonacciStrategy ->setCount(11) ->initialize();, <sub>(*9)</sub>

return $fibonacciStrategy->getSeries();, <sub>(*10)</sub>

```, <sub>(*11)</sub>

Result is [0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55]., <sub>(*12)</sub>
