User agent - extracting the browser type

I've got this variable from HTTP_USER_AGENT

Which comes up as Mozilla/5.0 (Windows; U; Windows NT 5.1; en-GB; rv:1.8.0.1) Gecko/20060111 Firefox/1.5.0.1

Does anyone know how I can determine which browser that is actually looking at the site. How could I determine between IE and Mozilla Firefox?

 

A simple way that I use is:

$useragent = getenv("HTTP_USER_AGENT"); 
if (preg_match("/MSIE/i", "$useragent")) 
{
$browser= "MSIE";
}
else if (preg_match("/Mozilla/i", "$useragent")) 
{
$browser= "Firefox";
}
else{
...........
}

PHP:

 

I had 1 come up that had Mozilla and MSIE in the same user agent.

Will that make a difference. I don't really know much about how the user agent variable is configured.

Thanks for the help Mad

 

Try http://www.phpclasses.org/browse/package/1663.html

 

An error in the script I posted is that you should detect the word Firefox rather than Mozilla to find the firefox browser.

This ties up with how the script at phpclasses does it.

 

Thanks T0Psy baby. I'll have a read this afternoon.
