environment's Introduction

Environment

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

Installation

To add Environment as a local, per-project dependency to your project, simply add a dependency on sebastian/environment to your project's composer.json file. Here is a minimal example of a composer.json file that just defines a dependency on Environment 1.0:

{
    "require": {
        "sebastian/environment": "1.0.*"
    }
}

Usage

<?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());
