<?php$refer = '';if (isset($_SERVER['HTTP_REFERER'])){ $refer = $_SERVER['HTTP_REFERER'];}$user_agent = '';if (isset($_SERVER['HTTP_USER_AGENT'])){ $user_agent = $_SERVER['HTTP_USER_AGENT'];}$ip = $_SERVER['REMOTE_ADDR'];if (isset($_GET['stay_ms'])){ $log = '[' . date("Y-m-d H:i:s") . '] ' . $ip . ' ' . $refer . ' @ ' . number_format($_GET['stay_ms']) . "ms\r\n"; file_put_contents("log/log_" . date("Y-m-d") . ".txt", $log, FILE_APPEND);}if ($_SERVER['QUERY_STRING'] == '' || isset($_GET['day'])){ $day = isset($_GET['day']) ? $_GET['day'] : date("Y-m-d"); $file = "log/log_" .$day . ".txt"; if (file_exists($file)) { $log = file_get_contents($file); echo nl2br($log); }} |
