$requestInformation = $_SERVER['REMOTE_ADDR'].', '.$_SERVER['HTTP_USER_AGENT'].', http://'.$_SERVER['HTTP_HOST'].htmlentities　　　　 ($_SERVER['PHP_SELF']). '?'.$_SERVER['QUERY_STRING']."n";
　$fileName = RootPath.'/log/'.date('Y-m-d').'.log'; //Website root directory RootPath It is in the configuration file define('RootPath', substr(dirname(__FILE__)));
　writeFile($fileName, $requestInformation, 'a'); //Indicates appending
