php獲取系統信息的方法

用 getenv函數進行處理：

<? = ('DOCUMENT_ROOT'); 
 = ('SERVER_PORT'); 
 = ('SCRIPT_NAME'); 
 = ('HTTP_USER_AGENT'); 
 = ('REQUEST_METHOD'); 
 = ('SERVER_PROTOCOL'); 
()， 
()， 
?>

示例：

<?() (例：Windows NT COMPUTER 5.1 build 2600('s') (或：('r') (例：5.1["HTTP_HOST"(['SERVER_NAME'["SERVER_ADDR"] (有時候獲取不到，推薦用：(['SERVER_NAME'['REMOTE_ADDR'['SERVER_SOFTWARE'['PROCESSOR_IDENTIFIER'['SystemRoot'['SERVER_NAME'] (建議使用：["HTTP_HOST"['USERDOMAIN'['HTTP_ACCEPT_LANGUAGE'['SERVER_PORT'?>
