If you ONLY need a very fast and simple function to detect the browser name (update to May 2016):

<?php

function get_browser_name($user_agent)
{
    if (strpos($user_agent, 'Opera') || strpos($user_agent, 'OPR/')) return 'Opera';
    elseif (strpos($user_agent, 'Edge')) return 'Edge';
    elseif (strpos($user_agent, 'Chrome')) return 'Chrome';
    elseif (strpos($user_agent, 'Safari')) return 'Safari';
    elseif (strpos($user_agent, 'Firefox')) return 'Firefox';
    elseif (strpos($user_agent, 'MSIE') || strpos($user_agent, 'Trident/7')) return 'Internet Explorer';
    
    return 'Other';
}

// Usage:

echo get_browser_name($_SERVER['HTTP_USER_AGENT']);

?>

This function also resolves the trouble with Edge (that contains in the user agent the string "Safari" and "Chrome"), with Chrome (contains the string "Safari") and IE11 (that do not contains 'MSIE' like all other IE versions).

Note that "strpos" is the fastest function to check a string (far better than "preg_match") and Opera + Edge + Chrome + Safari + Firefox + Internet Explorer are the most used browsers today (over 97%).
