This function will return the users operating system, or 'Unknown OS' if the code doesn't know. PHP: <?php function define_os () { global $_SERVER; define("USERAGENT", $_SERVER['HTTP_USER_AGENT']); $operatingSystems = array( 'Windows Vista' => '/windows nt 6.0/i', 'Windows Server 2003' => '/windows nt 5.2/i', 'Windows XP' => '/windows nt 5.1/i', 'Windows 2000 SP1' => '/windows nt 5.01', 'Windows 2000' => '/windows nt 5.0/i', 'Windows NT 4.0' => '/windows nt 4.0/i', 'Windows NT' => '/windows nt/i', 'Windows ME' => '/win 9x 4.90/i', 'Windows 98' => '/windows 98/i', 'Windows 95' => '/windows 95/i', 'Windows 3.x' => '/windows 3.1/i', 'Windows XP (IE7 Beta)' => '/win32/i', 'Linux' => '/linux/i', 'FreeBSD' => '/freebsd/i', 'NetBSD' => '/netbsd/i', 'OpenBSD' => '/openbsd/i', 'Mac (68000)' => '/mac_68000/i', 'Mac (PPC)' => '/mac_ppc/i', 'Mac PowerPC' => '/mac_powerpc/i', 'PPC Mac OS X' => '/ppc mac os x/i', 'SunOS' => '/sunos/i', 'Windows Vista Media Center' => '/media center pc 5.0/i', 'Windows Media Center' => '/media center pc/i', 'Windows Media Center' => '/mediacenter/i', 'Windows ME' => '/win 9x 4.90/i', 'Windows 98' => '/win98/i', 'Windows 95' => '/win95/i', ); $array['operating_system'] = 'Unknown OS'; foreach ($operatingSystems as $systemName => $pattern) { if(preg_match($pattern, USERAGENT)) { return $systemName; } } } // Browser name with a icon echo '<b>Your Operating System:</b> <i>' . define_os() . '</i>'; ?> I am working on the arrays of more operating systems to create a more detailed list of operating systems this code can show. I will update this topic soon. EDIT: More detailed list here, this is if you want to a wider variety of OS's: PHP: <?php function define_os () { global $_SERVER; define("USERAGENT", $_SERVER['HTTP_USER_AGENT']); $operatingSystems = array( 'Windows Vista' => '/windows nt 6.0/i', 'Windows Vista Media Center' => '/media center pc 5.0/i', 'Windows Media Center' => '/media center pc/i', 'Windows Media Center' => '/mediacenter/i', 'Windows Server 2003' => '/windows nt 5.2/i', 'Windows XP' => '/windows nt 5.1/i', 'Windows 2000 SP1' => '/windows nt 5.01', 'Windows 2000' => '/windows nt 5.0/i', 'Windows 2000 (Opera)' => '/windows 2000/i', 'Windows NT 4.0' => '/windows nt 4.0/i', 'Windows NT' => '/windows nt/i', 'Windows ME' => '/win 9x 4.90/i', 'Windows 98' => '/windows 98/i', 'Windows 95' => '/windows 95/i', 'Windows 3.x' => '/windows 3.1/i', 'Windows CE/Mobile' => '/windows ce/i', 'Windows CE 4.21' => '/windows ce 4.21/i', 'Windows XP (IE7 Beta)' => '/win32/i', 'Windows ME' => '/win 9x 4.90/i', 'Windows 98' => '/win98/i', 'Windows 95' => '/win95/i', 'Windows 3.11' => '/win3.11/i', 'Windows NT 3.51' => '/winnt3.51/i', 'Windows NT 4.0' => '/winnt4.0/i', 'Linux' => '/linux/i', 'Ubuntu Feisty Fawn' => '/\(Ubuntu-feisty\)/i', 'FreeBSD' => '/freebsd/i', 'NetBSD' => '/netbsd/i', 'OpenBSD' => '/openbsd/i', 'Mac (68000)' => '/mac_68000/i', 'Mac (PPC)' => '/mac_ppc/i', 'Mac PowerPC' => '/mac_powerpc/i', 'PPC Mac OS X' => '/ppc mac os x/i', 'PPC Mac OS X Mach-O' => '/ppc mac os X mach-O/i', 'Mac OS X (Intel)' => '/intel mac os x/i', 'SunOS' => '/sunos/i', 'Symbian OS (Mobile)' => '/symbian os/i', 'Nitro (Nintendo DS)' => '/nitro/i', 'Playstation Portable' => '/psp/i', 'Playstation 3' => '/playstation 3/i', 'Windows 64-bit' => '/win64/i', 'Intel Intanium Processor' => '/ia64/i', '64-bit AMD Athlon Processor' => '/amd64/i', 'x64 Processor' => '/x64/i', 'MSIE Crawler' => '/msiecrawler/i', 'SunOS (IE)' => '/x11/i', 'Pocket PC' => '/ppc/i', 'Smart Phone' => '/smartphone/i', 'Motorola Phone' => '/motorola/i', 'Nokia Phone' => '/nokia/i' ); $array['operating_system'] = 'Unknown OS'; foreach ($operatingSystems as $systemName => $pattern) { if(preg_match($pattern, USERAGENT)) { $return = $systemName; break; } } return $return; } // Browser name with a icon echo '<b>Your Operating System:</b> <i>' . define_os() .

Why thanks Bill. I do try to help people who aren't so wise in PHP. And no, I am not talking about you as Pandemix has told me of your skills
