Environment
This component provides functionality that helps writing PHP code that has runtime-specific (PHP / HHVM) execution paths.
[](https://packagist.org/packages/sebastian/environment) [](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()); ```
