The following would be implemented as an else-if, so if a 1 is true,
neither of the other checks are made. I think I've included all the
"major" browsers I could think of. The application doesn't have to be
perfect, but good enough. Also if a user is using firefox and set it
up to pretend to be IE, I guess its "OK" for me to store it as IE,
etc.
Anyone knows a better way to identify different browsers ?
1. check if the user-agent contains the word "googlebot" => "browser"
is googlebot
2. check if the user-agent contains the word "links" => browser is
Links
3. check if the user-agent contains the word "lynx" => browser is Lynx
4. check if the user-agent contains the word "safari" => browser is
Safari
5. check if the user-agent contains the word "opera" => browser is
Opera
6. check if the user-agent contains the word "omniweb" => browser is
omniweb
7. check if the user-agent contains the word "netscape" or "ns8" =>
browser is netscape
8. check if the user-agent contains the word "camino" or "chimera" =>
browser is camino
9. check if the user-agent contains the word "konqueror" => browser is
conqueror
10. check if the user-agent contains the word "msie" => browser is
most probably IE at this point
11. check if the user-agent contains the word "firefox" => brower is
most probably firefox
12. check if the user-agent contains the word "mozilla" => browser is
most probably mozilla
13. Browser underermined, "unknown"
Last time I did this for a script that ran stats via brute force method
like this I had about a thousand lines like this for different robots /
UAs / devices and such... Its a bit of a mess and my suggestion if you
were to do it would be - be careful. In the back side of things (like
for stats) its not an issue, but if doing it to try and sniff out a UA
to deliver content to thats just a bad idea as the other folks have
mentioned.
That said... I tend to think your list above goes at things kinda
sideways. It does not catch that netscape 4 and netscape 8 are two
totally different products, but netscape 8, firefox and netscape 8 may
not be. Same goes for IE on windows or mac. So you should twist the
categories a little... check for "gecko" much higher up then break
those out if need be (into camino/firefox/netscape/etc). Same goes for
the khtml/webkit browsers.
oh, and looking for mozilla, well, thats not going to get you too far
as a pile of UAs start their identifier out with Mozilla/X.X
