代码如下：
class CookieTool{..................protected function getIPAddress(): string{$ipaddress = "";if (isset($_SERVER['HTTP_CLIENT_IP']))$ipaddress = $_SERVER['HTTP_CLIENT_IP'];else if(isset($_SERVER['HTTP_X_FORWARDED_FOR']))$ipaddress = $_SERVER['HTTP_X_FORWARDED_FOR'];else if(isset($_SERVER['HTTP_X_FORWARDED']))$ipaddress = $_SERVER['HTTP_X_FORWARDED'];else if(isset($_SERVER['HTTP_FORWARDED_FOR']))$ipaddress = $_SERVER['HTTP_FORWARDED_FOR'];else if(isset($_SERVER['HTTP_FORWARDED']))$ipaddress = $_SERVER['HTTP_FORWARDED'];else if(isset($_SERVER['REMOTE_ADDR']))$ipaddress = $_SERVER['REMOTE_ADDR'];else$ipaddress = 'UNKNOWN';return $ipaddress;}protected function getBrowser($agent): string{$browserAgent = "";if(strstr($agent, 'MSIE')) {$browserAgent="Internet Explorer";}else if(strstr($agent, 'Opera')) {$browserAgent="Opera";}else if(strstr($agent, 'Firefox')) {$browserAgent="Firefox";}else if(strstr($agent, 'Chrome')) {$browserAgent = "Chrome";}else if(strstr($agent, 'Safari')) {$browserAgent = "Safari";}else{$browserAgent = "unknown";}return $browserAgent;}protected function getPlatform($agent): string{$agent = strtolower($agent);$platform = "";if(strstr($agent, 'win')) {$platform="windows";}else if(strstr($agent, 'linux')) {$platform = "linux";}else{$platform = "unknown";}return $platform;}protected function getMacAddress(): string{$MAC = exec('getmac');print_r($MAC);$MAC = strtok($MAC, ' ');return $MAC;}public function printCookieArray(){global $cookieAndSessionArray;print_r($cookieAndSessionArray);}public function XXXXXX(){$ipAddress = $this->getIPAddress();$browserAgent = $this->getBrowser($_SERVER['HTTP_USER_AGENT']);$platform = $this->getPlatform($_SERVER['HTTP_USER_AGENT']);echo $ipAddress . "<br/>";echo $browserAgent . "<br/>";echo $platform . "<br/>";}}
