# Environment

This component provides functionality that helps writing PHP code that has runtime-specific (PHP / HHVM) execution paths.

[![Latest Stable Version](https://poser.pugx.org/sebastian/environment/v/stable.png)](https://packagist.org/packages/sebastian/environment)
[![Build Status](https://travis-ci.org/sebastianbergmann/environment.png?branch=master)](https://travis-ci.org/sebastianbergmann/environment)

## Installation

You can add this library as a local, per-project dependency to your project using [Composer](https://getcomposer.org/):

    composer require sebastian/environment

If you only need this library during development, for instance to run your project's test suite, then you should add it as a development-time dependency:

    composer require --dev sebastian/environment

## Usage

```php
<?php
use SebastianBergmann\Environment\Runtime;

$runtime = new Runtime;

var_dump($runtime->getNameWithVersion());
var_dump($runtime->getName());
var_dump($runtime->getVersion());
var_dump($runtime->getBinary());
var_dump($runtime->isHHVM());
var_dump($runtime->isPHP());
var_dump($runtime->hasXdebug());
var_dump($runtime->canCollectCodeCoverage());
```
