Browser/OS Detector Class!

[Dark_Phoenix]

Okay, I wrote a class for detecting user's browser & OS if the server doesn't have a browscap. But I need your help! I need people to try it out and spot any errors that might remain in the program.

http://crystalsanctuary.thatfinalfantasysite.com/uitest.php

That leads to a test page that uses the program to detect your info. Post and tell me how accurate it is (please note I rounded off some version numbers; Opera & IE have 20 or so incarnations!).

I'll release the source code later; but first I want to make sure that it works on most browsers.

Also, if you have a browser you think I should add to the list, post and I'll add it.

Current browsers that can be detected:

IE4
IE5
IE5.5
IE6
NN4.x
NN6.x (untested)
NN7
Opera 4.x (untested)
Opera 5.x (untested)
Opera 6.x
Opera 7.x
Konqueror (all versions) (untested)
Mozilla 1.0
Mozilla 1.1
Mozilla 1.2
AOL 6.0
AOL 7.0
AOL 8.0

I checked out that page with

MSIE 6
Netscape7
Opera7
Mozilla 1.0.0

Right on the money every time.

I have a question for you.. How did you detect Opera 7?
This is what i'm doing. I've tried quite a few different ways, but no matter how I go about it, I can't seem to detect Opera 7!

<?php

$ip = getenv("REMOTE_ADDR");  // Getting the Internet Address
$usrcmp = getenv("HTTP_USER_AGENT");  // Getting misc. information 
$referrer = getenv("HTTP_REFERER");  // Getting Referrer

// Getting Operating System Information - INCOMPLETE
// I know for a fact that Mac and Win XP work. The rest I dont know!
if(strstr($usrcmp, "Windows 95")) $OS= 'Windows 95'; 
else if(strstr($usrcmp, "Windows 98")) $OS = 'Windows 98';
else if(strstr($usrcmp, "Windows 2000")) $OS = 'Windows 2000';
else if(strstr($usrcmp, "Windows NT 5.1")) $OS = 'Windows XP';
// else if(strstr($usrcmp, "Windows XP")) $OS = 'Windows XP';
else if(strstr($usrcmp, "Windows ME")) $OS = 'Windows ME';
else if(strstr($usrcmp, "Windows NT")) $OS = 'Windows NT';
else if(strstr($usrcmp, "Mac")) $OS = 'Macintosh';
else if(strstr($usrcmp, "Linux")) $OS = 'Linux';
else if(strstr($usrcmp, "Unix")) $OS = 'Unix';
else if(strstr($usrcmp, "Solaris")) $OS = 'Solaris';
else if(strstr($usrcmp, "FreeBSD")) $OS = 'FreeBSD'; // :shrug: dunno if that works or not.
else $OS = '<b>Unavailable!</b>';

// Getting Browser - INCOMPLETE
if(strstr($comp, "MSIE 7")) $browser = 'IE 7'; 
else if(strstr($usrcmp, "MSIE 6")) $browser = 'Internet Explorer 6';
else if(strstr($usrcmp, "MSIE 5")) $browser = 'Internet Explorer 5';
else if(strstr($usrcmp, "MSIE 4")) $browser = 'Internet Explorer 4';
else if(strstr($usrcmp, "Netscape7")) $browser = 'Netscape 7';
else if(strstr($usrcmp, "Netscape6")) $browser = 'Netscape 6';
else if(strstr($usrcmp, "Netscape5")) $browser = 'Netscape 5';

// I'm not sure if the rest of these are accurate!

else if(strstr($usrcmp, "Opera7")) $browser = 'Opera 7'; // displays as IE5 for some reason. :KoRnfused:
else if(strstr($usrcmp, "Opera6")) $browser = 'Opera 6';
else if(strstr($usrcmp, "Opera5")) $browser = 'Opera 5';
else if(strstr($usrcmp, "Mozilla 1.0.0")) $browser = 'Mozilla 1.0.0';
else if(strstr($usrcmp, "Mozilla 1.0.1")) $browser = 'Mozilla 1.0.1';
else if(strstr($usrcmp, "Mozilla 1.0.2")) $browser = 'Mozilla 1.0.2';
else $browser = '<b>Unavailable</b>';

echo "Browser: $browser<br />\nOperating System: $OS<br />\n";
echo "IP: $ip<br />\n";
if (!$referrer) { echo "Direct Hit<br />\n"; }
else {
echo "$referrer<br />\n"; }

?>

I'm running Windows XP
Using the code above, I visited the page with
Opera 7 - which returns Internet Explorer 6. Anyone know why?
Also, it says OS is Unavailable!

Netscape 7 - Browser is Unavailable
OS - Windows XP

Same for Mozilla 1.0.0

Everything seemed to work fine when I visited with Internet Explorer 6.

Any suggestions / Fixes ?

I did it like this:

	if(ereg("Opera", $http_user_agent))
		{
			$this->browsername = "Opera";
			if(ereg("Mozilla", $http_user_agent))
			{
				ereg("Opera ([0-9\\.]*)", $http_user_agent, $numbers);
				$this->browserversion = $numbers[1];
			}else{
				ereg("Opera/([0-9\\.]*)", $http_user_agent, $numbers);
				$this->browserversion = $numbers[1];
			}
			if(ereg("4\\.", $this->browserversion))
			{
				$this->browserversion = "4";
			}
			if(ereg("5\\.", $this->browserversion))
			{
				$this->browserversion = "5";
			}
			if(ereg("6\\.", $this->browserversion))
			{
				$this->browserversion = "6";
			}
			if(ereg("7\\.", $this->browserversion))
			{
				$this->browserversion = "7";
			}
			if(ereg("Windows 2000", $http_user_agent))
			{
				$this->os = "Windows 2000";
			}
			if(ereg("Windows 95", $http_user_agent))
			{
				$this->os = "Windows 95";
			}
			if(ereg("Windows 98", $http_user_agent))
			{
				$this->os = "Windows 98";
			}
			if(ereg("Windows NT 4.0", $http_user_agent))
			{
				$this->os = "Windows NT";
			}
			if(ereg("Windows ME", $http_user_agent))
			{
				$this->os = "Windows ME";
			}
			if(ereg("Windows XP", $http_user_agent))
			{
				$this->os = "Windows XP";
			}
			if(ereg("Linux", $http_user_agent))
			{
				$this->os = "Linux";
			}
			if(ereg("SunOS", $http_user_agent))
			{
				$this->os = "Solaris";
			}
			if(ereg("Mac_PowerPC", $http_user_agent))
			{
				$this->os = "Macintosh";
			}
			if(ereg("OS/2", $http_user_agent))
			{
				$this->os = "OS/2";
			}

The problem with Opera is unlike Internet Explorer & Netscape Navigator, Opera's HTTP_USER_AGENT result can differ; the reason you get IE6 is because in your case, Opera is probably using this incarnation:

Mozilla/4.0 (compatible; MSIE 6.0; MSIE 5.5; (your OS)) Opera 7.0

Opera has one defining characteristic; it alwas puts "Opera" SOMEWHERE in the HTTP_USER_AGENT string.

As for Netscape 7, they made a change in the way the string looks. In Netscape 6, it was Netscape6/6.2, but in Netscape 7 it's Netscape/7.0.

Netscape Communicator was much harder, 'cause Communicator has NO defining characteristics; so I had to locate it by making sure it wasn't something else 😉

This is quite impressive

A few notes about OS detection:

Windows 95 sometimes shows up as Win95.
Windows 3.1 sometimes shows up as Windows16.
Windows 98 sometimes shows up as Win98.
Windows NT sometimes shows up as WinNT.
Windows 2000 sometimes shows up as Windows NT 5.0.
Windows XP sometimes shows up as Windows NT 5.1.
Windows ME sometimes shows up as Win 9x 4.90.
Linux and FreeBSD can show up as X11; however, FreeBSD will ALWAYS have FreeBSD imbedded somewhere.
Solaris shows up as SunOS ALL THE TIME.
Macintosh shows up as Mac_PowerPC; that's why yours works.

BTW, anyone out there have a working copy of the MSN Browser? I'd like to get a look at a copy of the HTTP_USER_AGENT for that (I have a feeling I know what it'll look like, but I want to see anyway).

The Mozilla browser which ships with Suse Linux 8.0 Professional shows up as

"Mozilla running on Linux"

$_SERVER["HTTP_USER_AGENT"] is
Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.8) Gecko/20020204

The Konqueror browser (also with Suse Linux 8.0) yields
Netscape Communicator 5.0 running on Linux

$_SERVER["HTTP_USER_AGENT"] is
Mozilla/5.0 (compatible; Konqueror/3.0.0; Linux)

nice, reported correctly with IE 5 and windows 2000(well, its professional, but ill let it slide) nice!

[Dark_Phoenix]

Okay, I fixed the problems.

For Mozilla, it was because I didn't plan for versions of Mozilla lower than 1.0, but now there's a 0.9 option.

For Konqueror, I forgot to tell the program that if it finds "Konqueror", then it's not Netscape Communicator (because NC doesn't have anything to mark it as different than the other browsers, so I have to make sure the browser ISN'T anything else, but still qualifies).

For the types of OS'es, there is no way to tell what version of Windows 2000 it is, or anything else (this wouldn't be able to tell the difference between the types of Windows XP either; because this info isn't sent in the string).

Updated the browser test list 🙂
