PHP记录来访IP,记录来访UA,记录时间,UserAgent记录代码源码

自动记录来访ip和ua并在同目录下生成一个ua.txt文本 海宁家政

<?php
header('Content-type: text/html; charset=utf-8');
$time = date('Y-m-d H:i:s',time());
$ip = $_SERVER["REMOTE_ADDR"];
$ua = $_SERVER["HTTP_USER_AGENT"];
$file = fopen("ua.txt",  "a+");
fwrite( $file, "($time|$ip|$ua)\r\n");
?>
