$oses = array (

‘Windows 95’ => ‘(Windows 95)|(Win95)|(Windows_95)’, // Use regular expressions as value to identify operating system

foreach($oses as $os=>$pattern){ // Loop through $oses array
// Use regular expressions to check operating system type
if(eregi($pattern, $userAgent)) { // Check if a value in $oses array matches current user agent.
return $os; // Operating system was matched so return $oses key
return ‘Unknown’; // Cannot find operating system so return Unknown
