detect the operating system using php

Question

am writing a command line app using php, o need to automatically detect the os, so far i have the following code for detectOS method

public function detectOS() 
{
    $user_agent = $_SERVER['HTTP_USER_AGENT'];

    // is it linux?
    if(preg_match('/linux/i', $user_agent))
    {
        $this->env = new Linux;
        return $this->env;
    }

    // is it windows?
    if(preg_match('/windows/i', $user_agent))
    {
        $this->env = new Windows;
        return $this->env;
    }

    // is it mac
    if(preg_match('/mac/i', $user_agent))
    {
        $this->env = new Mac;
        return $this->env;
    }

    return false;
}

and this is the test am using for that method

// -------------------------------------------------- detectOS
public function testOsIsLinux()
{
    $os = new OS($this->path);
    $env_name = $os->detectOS();

    $this->assertInstanceOf('Linux', $os->env);
}

when i run the test i get the following error

PHPUnit_Framework_Exception: Undefined index: HTTP_USER_AGENT

so i guess that i need a native php function to detect the os am on.

any ideas, or i just implement it in python?

its a command line app, get_browser is not working because am not running any server, please read the my question first, i already tell that HTTP_USER_AGENT is an undefined index. — Oussama Elgoumri, Dec 11 '14 at 08:10
because i need to do some system stuff, and write custom class for each system. — Oussama Elgoumri, Dec 11 '14 at 08:12

The question was answered before, indeed, but it is a duplicate of a different question. The correct one is the one provided by mark91. — axiac, Dec 11 '14 at 09:15
