Browser detection (suggestion)

[eevan79]

Here is my simple script for user browser and OS detection:

 

$agent = $_SERVER['HTTP_USER_AGENT'];
  
  if (strstr($agent,"Windows")) {$os = "Windows";}
  if (strstr($agent,"Windows NT 6")) {$os = "Windows 7";}
  if (strstr($agent,"Linux")) {$os = "Linux";}
  if (strstr($agent,"Intel Mac OS X")) {$os = "OS X";}
  if (strstr($agent,"OpenBSD")) {$os = "BSD";}
  if (strstr($agent,"FreeBSD")) {$os = "FreeBSD";}
  
  if (strstr($agent,"Firefox/3")) {$br = "Firefox 3";}
  if (strstr($agent,"Firefox/2")) {$br = "Firefox 2";}
  if (strstr($agent,"Firefox/1")) {$br = "Firefox 1";}
  if (strstr($agent,"Phoenix/")) {$br = "Phoenix (Mozilla lite)";}
  if (strstr($agent,"MSIE 6")) {$br = "IE 6";}
  if (strstr($agent,"MSIE 7")) {$br = "IE 7";}
  if (strstr($agent,"MSIE 8")) {$br = "IE 8";}
  if (strstr($agent,"Netscape6/6")) {$br = "Netscape 6";}
  if (strstr($agent,"Opera")) {$br = "Opera";}
  if (strstr($agent,"Opera") and strstr($agent,"Version/10")) {$br = "Opera 10";}
  if (strstr($agent,"Opera") and strstr($agent,"Version/9")) {$br = "Opera 9";}
  if (strstr($agent,"Chrome") and strstr($agent,"Chrome/5")) {$br = "Chrome 5";}
  if (strstr($agent,"Safari/")) {$br = "Safari";}
  if (strstr($agent,"Safari/") and strstr($agent,"Version/5")) {$br = "Safari 5";}
  if (strstr($agent,"Safari/") and strstr($agent,"Version/4")) {$br = "Safari 4";}
  if (strstr($agent,"Safari/") and strstr($agent,"Version/3")) {$br = "Safari 3";}
  if (strstr($agent,"SeaMonkey/") and strstr($agent,"Gecko")) {$br = "SeaMonkey";}

  echo "Browser: <b>$br</b>, OS: <b>$os</b>";

I found some information from here: http://www.zytrax.com/tech/web/browser_ids.htm

 

Is there any better solution for this, or script above is accurate?

you should look into browscap, I never worked with it before but I have actually ran into it a couple times, it should actually help you alot, and there are TONS of browscap.ini downloads across the internet

[eevan79]

Thanks, I have searched for some browser caps, and its basicaly user_agent database .

 

I dont need so much information, just for most used browsers and OS. Also, I have tested this script above with different browsers and OS and its working fine.

 

If anyone have better suggestion, feel free to share with us.

browscap is an ini file full of browsers and information about them, if you want to include a huge chunk of unattractive if statements for user agents than you'd do it your way

 

browscap is the best alternative to this.. and probably better than what you've got going because new browscap.ini files come out whenever a new browser comes out.. + you only check for what 10 browsers? most browscap.ini variations have pretty much every distributed browser besides homemade ones from kids with visual basic..

 

ALSO your checks are pretty redundant in the way that if it alrdy matches "windows 7" why would you check for linux.. you feel me?

 

 

[eevan79]

Ok, I understand.

 

Anyway, I just want to make small stats for users and their OS/Browsers. Dont need huge browsers database. For example:

FF - 45%, IE - 15%, Opera - 25%, Netscape - 5%

and same for OS (Win - Xp/7/98, Linux... ) .

 

I can also try this with browcap. Solved and thanks for suggestions.

My server, which I do not control, does not have a browsecap file so I can't use that. Hence, I need this guy's series of IF/THEN statements just to get me somewhere in the ballpark.

you probably would want to change it to if/else then instead of if if if if ;P
