phpip查询
function getIP() {
$url=file_get_contents("";);
$ip=substr($url,85);
$ip=substr($ip,0,-4);
return $ip;
}
一个大神抛出的，不过需要访问一个链接（总是感觉慌慌的），建议用tp自带函数访问不到的再用这个方法
⑵ 用php如何获得用户ip地址
$ip = $_SERVER["REMOTE_ADDR"];
echo $ip;
//方法2：
$user_IP = ($_SERVER["HTTP_VIA"]) ? $_SERVER["HTTP_X_FORWARDED_FOR"] :
$_SERVER["REMOTE_ADDR"];
$user_IP = ($user_IP) ? $user_IP : $_SERVER["REMOTE_ADDR"];
echo $user_IP;
//方法3：
function getRealIp()
{
$ip=false;
if(!empty($_SERVER["HTTP_CLIENT_IP"])){
$ip = $_SERVER["HTTP_CLIENT_IP"];
}
if (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])) {
$ips = explode (", ", $_SERVER['HTTP_X_FORWARDED_FOR']);
if ($ip) { array_unshift($ips, $ip); $ip = FALSE; }
for ($i = 0; $i < count($ips); $i++) {
if (!eregi ("^(10│172.16│192.168).", $ips[$i])) {
$ip = $ips[$i];
break;
}
}
}
return ($ip ? $ip : $_SERVER['REMOTE_ADDR']);
}
echo getRealIp();
//方法4：
if ($HTTP_SERVER_VARS["HTTP_X_FORWARDED_FOR"])
{
$ip = $HTTP_SERVER_VARS["HTTP_X_FORWARDED_FOR"];
}
elseif ($HTTP_SERVER_VARS["HTTP_CLIENT_IP"])
{
$ip = $HTTP_SERVER_VARS["HTTP_CLIENT_IP"];
}
elseif ($HTTP_SERVER_VARS["REMOTE_ADDR"])
{
$ip = $HTTP_SERVER_VARS["REMOTE_ADDR"];
}
elseif (getenv("HTTP_X_FORWARDED_FOR"))
{
$ip = getenv("HTTP_X_FORWARDED_FOR");
}
elseif (getenv("HTTP_CLIENT_IP"))
{
$ip = getenv("HTTP_CLIENT_IP");
}
elseif (getenv("REMOTE_ADDR"))
{
$ip = getenv("REMOTE_ADDR");
}
else
{
$ip = "Unknown";
}
echo $ip ;
//方法5：
if(getenv('HTTP_CLIENT_IP')) {
$onlineip = getenv('HTTP_CLIENT_IP');
} elseif(getenv('HTTP_X_FORWARDED_FOR')) {
$onlineip = getenv('HTTP_X_FORWARDED_FOR');
} elseif(getenv('REMOTE_ADDR')) {
$onlineip = getenv('REMOTE_ADDR');
} else {
$onlineip = $HTTP_SERVER_VARS['REMOTE_ADDR'];
}
echo $onlineip;

调用方法:
$iploca = new ip_location;
$iploca -> init();
$iploca -> getiplocation($ip);
$area['country'] = str_replace(array('CZ88.NET'), '', $iploca -> get('country'));
$area['area'] = str_replace(array('CZ88.NET'), '', $iploca -> get('area'));
$area['country']=='' && $area['country']='未知';
$area['area']=='' && $area['area']='未知';
return $area;
⑷ php到底怎么获取IP地址，为什么三种方法获取的IP都不一样
你电脑接了路由器，127.0.0.1是本地回环地址，网上测试那个是公网IP地址，本机做服务器，服务器地址就是127.0.0.1
⑸ 利用php怎么获取用户ip
php获取用户真实ip的方法：
方法1：
//获取REMOTE_ADDR属性，直接可以得到ip
$ip = $_SERVER["REMOTE_ADDR"];
echo $ip;
方法2：
//从Server中获取HTTP_VIA，如果获取到就用HTTP_X_FORWARDED_FOR的值替换，如果获取不到就取REMOTE_ADDR的值。
$user_IP = ($_SERVER["HTTP_VIA"]) ? $_SERVER["HTTP_X_FORWARDED_FOR"] :
$_SERVER["REMOTE_ADDR"];
$user_IP = ($user_IP) ? $user_IP : $_SERVER["REMOTE_ADDR"];
echo $user_IP;
方法3：
function getRealIp()
{
$ip=false; //初始化ip为false
if(!empty($_SERVER["HTTP_CLIENT_IP"])){ //如果HTTP_CLIENT_IP不为空
$ip = $_SERVER["HTTP_CLIENT_IP"]; //获取HTTP_CLIENT_IP的值
}
if (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])) { //如果HTTP_X_FORWARDED_FOR不为空
$ips = explode (", ", $_SERVER['HTTP_X_FORWARDED_FOR']);
//把HTTP_X_FORWARDED_FOR的值用,分割后存放数组ips
if ($ip) { array_unshift($ips, $ip); $ip = FALSE; }//遍历处理
for ($i = 0; $i < count($ips); $i++) {
if (!eregi ("^(10│172.16│192.168).", $ips[$i])) {
$ip = $ips[$i]; //获得真实ip
break;
}
}
}
return ($ip ? $ip : $_SERVER['REMOTE_ADDR']);
}
echo getRealIp();
⑹ php 根据url 获取ip及端口
你可以试一下这个，比如你要想知道wqzbxh.top这个域名对应的IP 可以使用以下函数：
$hosts=gethostbynamel('wqzbxh.top'); //获取ip地址列表
print_r($hosts);
返回结是数组形式的返回结果：
⑺ php获取本机主板网卡IP地址.跳转读取相应的数据
大家一般都是用$_SERVER['REMOTE_ADDR']来获取用户IP，
但是如果使用了反向代理的，HTTP头中REMOTE_ADDR就不是用户的地址，反而是上一级代理的地址了。
经过我的研究有两种方法来获取用户的真实外网IP。
方法一：curl
复制代码代码如下:
function get_onlineip() {
$ch = curl_init('http://www.ip138.com/ip2city.asp');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$a = curl_exec($ch);
preg_match('/\[(.*)\]/', $a, $ip);
return $ip[1];
}
方法二：$_SERVER['HTTP_X_FORWARDED_FOR']来获取相应的地址
复制代码代码如下:
function get_onlineip() {
$onlineip = '';
if(getenv('HTTP_CLIENT_IP') && strcasecmp(getenv('HTTP_CLIENT_IP'), 'unknown')) {
$onlineip = getenv('HTTP_CLIENT_IP');
} elseif(getenv('HTTP_X_FORWARDED_FOR') && strcasecmp(getenv('HTTP_X_FORWARDED_FOR'), 'unknown')) {
$onlineip = getenv('HTTP_X_FORWARDED_FOR');
} elseif(getenv('REMOTE_ADDR') && strcasecmp(getenv('REMOTE_ADDR'), 'unknown')) {
$onlineip = getenv('REMOTE_ADDR');
} elseif(isset($_SERVER['REMOTE_ADDR']) && $_SERVER['REMOTE_ADDR'] && strcasecmp($_SERVER['REMOTE_ADDR'], 'unknown')) {
$onlineip = $_SERVER['REMOTE_ADDR'];
}
return $onlineip;
}
⑻ 如何使用php获取本机IP地址
function ip() {
if(getenv('HTTP_CLIENT_IP') && strcasecmp(getenv('HTTP_CLIENT_IP'), 'unknown')) {
$ip = getenv('HTTP_CLIENT_IP');
} elseif(getenv('HTTP_X_FORWARDED_FOR') && strcasecmp(getenv('HTTP_X_FORWARDED_FOR'), 'unknown')) {
$ip = getenv('HTTP_X_FORWARDED_FOR');
} elseif(getenv('REMOTE_ADDR') && strcasecmp(getenv('REMOTE_ADDR'), 'unknown')) {
$ip = getenv('REMOTE_ADDR');
} elseif(isset($_SERVER['REMOTE_ADDR']) && $_SERVER['REMOTE_ADDR'] && strcasecmp($_SERVER['REMOTE_ADDR'], 'unknown')) {
$ip = $_SERVER['REMOTE_ADDR'];
}
return preg_match ( '/[\d\.]{7,15}/', $ip, $matches ) ? $matches [0] : '';
}
以上函数取自phpcms的获取ip方法
