Installation
------------

[](#installation)

The recommended way to install bundle is through [Composer](http://getcomposer.org/):

```
$ composer require sharkzt/fibonacci
```

Usage Examples
--------------

[](#usage-examples)

### Singleton

[](#singleton)

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

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

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

### Adapter

[](#adapter)

```
//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 \[0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55\].

### Strategy

[](#strategy)

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

return $fibonacciStrategy->getSeries();

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

return $fibonacciStrategy->getSeries();
```

Result is \[0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55\].
