# Streamer

Streamer is an Object-Oriented API for PHP streams.

## Why should I use Streams?

A stream is a flow of bytes from one container to the other. You already use streams a lot in PHP, for instance each time you load a file into memory (`file_get_contents()`). You should explicitly use streams each time that:

* You need to access data from a container, but you don't know the size of this container (e.g. reading from STDIN, or a web service using streaming)

* You need to start processing data from a container before the whole transfer is finished (e.g. start zipping a file before it's all in memory)

* You need to save time and memory

## What is Streamer?

PHP has a very elaborate stream API ; unfortunately, it uses functions for most stream operations (except for wrappers - go figure). Streamer is a generic library focusing on offering an object-oriented API to streams, and only that.

## Installation

Streamer is published on [packagist.org](http://packagist.org/packages/fzaninotto/Streamer), so you can add it to your `composer.json` file for an easy installation:

```sh

composer require fzaninotto/Streamer

```

or

```json

{

    "require": {

        "fzaninotto/Streamer": "0.0.1"

    }

}

```

## Example

```php

isEOF()) {

  $image .= $stream->read();

}

// pipe dreams!

$stream1 = new Stream(fopen('smiley.png', 'r'));

$stream2 = new Stream(fopen('tmp.png', 'w'));

// copy the contents from the first stream to the second one

$stream1->pipe($stream2);

// factory

$fileStream = FileStream::create('smiley.png', 'r');

print_r($fileStream);

$networkStream = NetworkStream::create('tcp://www.google.com:80');

print_r($networkStream);

```
