CancioLabs / DS / PHP-Queue
===========================

[](#canciolabs--ds--php-queue)

This tiny package contains an interface and an array-based implementation of the FIFO Queue data structure.

Interface
---------

[](#interface)

The Queue interface extends both Countable and IteratorAggragate interfaces, so it's possible to use a queue object inside the count function and foreach loop.

### Methods

[](#methods)

MethodDescriptionenqueueAdds a new element to the back of the queue.dequeueRemoves and return the front element from the queue.backReturns the back element of the queue.frontReturns the front element of the queue.isEmptyTests whether the queue is empty.clearRemoves all elements from the queue.countReturns the number of elements of the queue.getIteratorReturns a QueueIterator.toArrayTransforms the queue into an array.How to use it
-------------

[](#how-to-use-it)

```
use CancioLabs\Ds\Queue\Queue;

$queue = new Queue(['A', 'B']);

$queue->enqueue('C');
$queue->enqueue('D');

$queue->isEmpty(); // returns false
$queue->count(); // returns 4
count($queue) // returns 4

$queue->front(); // output 'A'
$queue->back(); // output 'D'
$queue->dequeue(); // output 'A'

$array = $queue->toArray(); // returns ['B', 'C', 'D']

foreach ($queue as $element) {
    // i=0: $element = 'B'
    // i=1: $element = 'C'
    // i=2: $element = 'D'
}

$queue->isEmpty(); // returns true

```
