Script Name: Full Featured PHP Browser/OS detection

Special thanks to alanjstr for cleaning up the code, especially on function get_item_version(), which he improved
greatly. Also to Tapio Markula, for his initial inspiration of creating a useable php browser detector.

/******************************************
this is currently set to accept these parameters, although you can add as many as you want:
1. safe - returns true/false, you can determine what makes the browser be safe lower down,
currently it's set for ns4 and pre version 1 mozillas not being safe, plus all older browsers
2. ie_version - tests to see what general IE it is, ie5x-6, ie4, or ieMac, returns these values.
3. moz_version - returns array of moz version, version number (includes full version, + etc), rv number (for math
comparison), rv number (for full rv, including alpha and beta versions), and release date
4. dom - returns true/false if it is a basic dom browser, ie >= 5, opera >= 5, all new mozillas, safaris, konquerors
5. os - returns which os is being used - win, nt, mac, OR iphone, blackberry, palmos, palmsource,
symbian, beos, os2, amiga, webtv, linux, unix.
6. os_number - returns windows versions, 95, 98, ce, me, nt: 4; 5 [windows 2000];
5.1 [windows xp]; 5.2 [Server 2003]; 6.0 [Windows Vista], 6.1 [Windows 7].
Only win, nt, mac, iphone return os numbers (mac/iphone return 10 if OS X.)
OR returns linux distro/unix release name, otherwise returns null
7. browser - returns the browser name, in shorthand: ie, ie4, ie5x, op, moz, konq, saf, ns4
8. number - returns the browser version number, if available, otherwise returns '' [not available]
9. full - returns this array: $browser_name, $browser_version_number, $ie_version, $dom_browser,
$safe_browser, $os_type, $os_number, $s_browser [the browser search string from the browser array],
$ua_type, $math_version_number, $a_moz_data, $a_webkit_data, $mobile_test (null or string value),
$a_mobile_data (null or array of mobile data)
Note that moz/webkit_data are arrays which could contain null data, so always test first before
assuming the moz/webkit arrays contain any data, ie, if moz or if webkit, then...
10. type - returns: bot (web bot); bro (normal browser); bbro (simple browser); mobile (handheld)
dow (downloading agent); lib (http library)
11. math_number - returns basic version number, for math comparison, ie. 1.2rel2a becomes 1.2
12. webkit_version - returns array of webkit version name (Eg. Chrome), webkit version number
(Eg. Chrome's: 1.2), and the actual webkit version number (Eg. Webkit's: 436)
13. mobile_test - returns a string of various mobile id methods, from device to os to browser.
If string is not null, should be a mobile. Also see 10, 'type', which will be 'mobile' if handheld.
14. mobile_data - returns an array of data about mobiles. Note the browser/os number data is very
unreliable so don't count on that. No blackberry version handling done explicitly.
Make sure to test if this is an array because if it's not mobile it will be null, not an array
$mobile_device, $mobile_browser, $mobile_browser_number, $mobile_os, $mobile_os_number,
$mobile_server, $mobile_server_number
Note: $mobile_browser only returns if a specifically mobile browser is detected, like minimo.
Same for mobile os, with the exception of linux. Otherwise the standard script os/browser data
is used. $mobile_server is a handheld service like docomo, novarro-vision, etc. Sometimes the
string will contain no other usable data than this to determine if it's handheld or not.
