nexusphp使用cf cdn后，无法获取到pt站用户当前真实ip解决办法，HTTP_X_FORWARDED_FOR只获取第一个xff地址

include文件夹打开文件globalfunctions.php
源代码

function getip() {
if (isset($_SERVER)) {
if (isset($_SERVER['HTTP_X_FORWARDED_FOR']) && validip($_SERVER['HTTP_X_FORWARDED_FOR'])) {
$ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
} elseif (isset($_SERVER['HTTP_CLIENT_IP']) && validip($_SERVER['HTTP_CLIENT_IP'])) {
$ip = $_SERVER['HTTP_CLIENT_IP'];
} else {
$ip = $_SERVER['REMOTE_ADDR'];
}
} else {
if (getenv('HTTP_X_FORWARDED_FOR') && validip(getenv('HTTP_X_FORWARDED_FOR'))) {
$ip = getenv('HTTP_X_FORWARDED_FOR');
} elseif (getenv('HTTP_CLIENT_IP') && validip(getenv('HTTP_CLIENT_IP'))) {
$ip = getenv('HTTP_CLIENT_IP');
} else {
$ip = getenv('REMOTE_ADDR');
}
}
return $ip;
}

新代码

function getip() {
if (isset($_SERVER)) {
if (isset($_SERVER['HTTP_CLIENT_IP']) && validip($_SERVER['HTTP_CLIENT_IP'])) {
$ip = $_SERVER['HTTP_CLIENT_IP'];
} elseif (isset($_SERVER['HTTP_X_FORWARDED_FOR']) && preg_match_all('#\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}#s', $_SERVER['HTTP_X_FORWARDED_FOR'], $matches)) {
$ip = $matches[0][0];
} else {
$ip = $_SERVER['REMOTE_ADDR'];
}
} else {
if (getenv('HTTP_CLIENT_IP') && validip(getenv('HTTP_CLIENT_IP'))) {
$ip = getenv('HTTP_CLIENT_IP');
} elseif (getenv('HTTP_X_FORWARDED_FOR') && preg_match_all('#\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}#s', getenv('HTTP_X_FORWARDED_FOR'), $matches)) {
$ip = $matches[0][0];
