Question

I have a PHP web page. I want to detect if browser is Firefox 3.6 or above. Can this be accomplished my just a browser-agent sniffing or is there any other way (since user agent can be customized).

since you are using PHP, there’s already an often updating PHP Class is there. Do have a look at it, as it features all.

Using the plugin is very simple:

<?php
    require_once('Browser.php');
    $browser = new Browser();
    if( ! ( $browser->getBrowser() == Browser::BROWSER_FIREFOX && $browser->getVersion() >= 3 ) )
    {
        echo 'You have FireFox version 3 or greater';
    }
?>

For getting that Browser.php, please download it from: http://chrisschuld.com/projects/browser-php-detecting-a-users-browser-from-php/

Hope this helps! 🙂
