Joomla provides the JBrowser class that provides convenience methods to extract client browser details from the user agent string.

You first create instance of the Jbrowser object. Pass in the user agent string for JBrowser to parse.

jimport('joomla.environment.browser');
$browser = &JBrowser::getInstance($_SERVER['HTTP_USER_AGENT']);

This will retrieve the name of the browser. Some of the browser types it returns: konqueror (safari), opera, mozilla, msie, palm, blackberry, nokia, iphone etc..

$browserName = $browser->getBrowser();

This will retrieve the version number of browser

$browserVersion = $browser->getMajor();

Some other things you can do with JBrowser

//Returns name of client's operating system
$os = $browser->getPlatform();
//Returns the decimal portion of the version number
$minor = $browser->getMinor();
//checks if browser has certain capability. Returns boolean.
$hasJs = $browser->hasFeature('javascript');
