本文介绍如何使用PHP获取用户的真实ip，并且写入到txt文档
首先创建一个php文件，将下面代码放到PHP文件中
<?php function getIp() { if (getenv("HTTP_CLIENT_IP") && strcasecmp(getenv("HTTP_CLIENT_IP"), "unknown")) $ip = getenv("HTTP_CLIENT_IP"); else if (getenv("HTTP_X_FORWARDED_FOR") && strcasecmp(getenv("HTTP_X_FORWARDED_FOR"), "unknown")) $ip = getenv("HTTP_X_FORWARDED_FOR"); else if (getenv("REMOTE_ADDR") && strcasecmp(getenv("REMOTE_ADDR"), "unknown")) $ip = getenv("REMOTE_ADDR"); else if (isset ($_SERVER['REMOTE_ADDR']) && $_SERVER['REMOTE_ADDR'] && strcasecmp($_SERVER['REMOTE_ADDR'], "unknown")) $ip = $_SERVER['REMOTE_ADDR']; else $ip = "unknown"; return ($ip); } //输出ip $myfile = fopen("ip.txt", "a+") or die("Unable to open file!"); $txt = "ip:"; fwrite($myfile, $txt); $txt = getIp(); fwrite($myfile, $txt); $txt = "时间:"; fwrite($myfile, $txt); $txt = date('Y-m-d h:i:s', time()); fwrite($myfile, $txt); $txt = "\n"; fwrite($myfile, $txt); fclose($myfile); ?>
然后在连接起来就可以了
