There's also a built-in function in PHP to achieve this and more: get_browser().

$agent = get_browser();
echo $agent->platform;
echo $agent->parent; // or $agent->browser . $agent->version

@augustknight: Note, the IE11 doesn´t send a "MSIE" token, i would suggest to add a match to a Trident token.

IE 11 user agent sample:

Mozilla/5.0 (Windows NT 6.1; Trident/7.0; rv:11.0) like Gecko

change code:

<?php
public static function getUserAgent()
{
    static $agent = null;

    if ( empty($agent) ) {
        $agent = $_SERVER['HTTP_USER_AGENT'];

        if ( stripos($agent, 'Firefox') !== false ) {
            $agent = 'firefox';
        } elseif ( stripos($agent, 'MSIE') !== false ) {
            $agent = 'ie';
        } elseif ( stripos($agent, 'Trident') !== false ) {
            $agent = 'ie';
        } elseif ( stripos($agent, 'iPad') !== false ) {
            $agent = 'ipad';
        } elseif ( stripos($agent, 'Android') !== false ) {
            $agent = 'android';
        } elseif ( stripos($agent, 'Chrome') !== false ) {
            $agent = 'chrome';
        } elseif ( stripos($agent, 'Safari') !== false ) {
            $agent = 'safari';
        } elseif ( stripos($agent, 'AIR') !== false ) {
            $agent = 'air';
        } elseif ( stripos($agent, 'Fluid') !== false ) {
            $agent = 'fluid';
        }

    }

    return $agent;
}

?>

I think it is tricky to get the full OS name and full browser name since many browsers identify themselves differently. You will probably need some fancy regex and then it might not even work 100% of the time.

Here is the simple method I use to identify the browser. You may be able to adapt it to suit your needs.

<?php

public static function getUserAgent()
{
    static $agent = null;

    if ( empty($agent) ) {
        $agent = $_SERVER['HTTP_USER_AGENT'];

        if ( stripos($agent, 'Firefox') !== false ) {
            $agent = 'firefox';
        } elseif ( stripos($agent, 'MSIE') !== false ) {
            $agent = 'ie';
        } elseif ( stripos($agent, 'iPad') !== false ) {
            $agent = 'ipad';
        } elseif ( stripos($agent, 'Android') !== false ) {
            $agent = 'android';
        } elseif ( stripos($agent, 'Chrome') !== false ) {
            $agent = 'chrome';
        } elseif ( stripos($agent, 'Safari') !== false ) {
            $agent = 'safari';
        } elseif ( stripos($agent, 'AIR') !== false ) {
            $agent = 'air';
        } elseif ( stripos($agent, 'Fluid') !== false ) {
            $agent = 'fluid';
        }

    }

    return $agent;
}
