㈠ 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 $onlineip;
㈡ PHP根据Ip跳转
在最后加个判断就可以了吧!
比如:
if(in_array($cip,$lip)){
echo"<scriptlanguage='javascript'type='text/javascript'>window.location.href='$jump_domain'</script>";
}
㈢ php获取ip
$user_IP=$_SERVER["REMOTE_ADDR"];//获取访问者IP
$file_name=date('Y-m-d').'.txt'//以当前的日期建立txt文件
$file=fopen($file_name,"a+");//如果存在该文件就打开，如果不存在就创建
fwrite($file,$user_IP.'--'.date('Y-m-dH:i:s'));//将访问者IP及当前时刻写到文件最后
fclose($file);//关闭文件
//个人觉得txt文件不会很大所以一般无需一天一删除，因为在txt里删除一些行比起数据库要麻烦一些。
㈣ php 怎么获取记录ip所在地
<?php
header('Content-Type:text/html;Charset=utf-8');
function GetIp(){
$realip = '';
$unknown = 'unknown';
if (isset($_SERVER)){
if(isset($_SERVER['HTTP_X_FORWARDED_FOR']) && !empty($_SERVER['HTTP_X_FORWARDED_FOR']) && strcasecmp($_SERVER['HTTP_X_FORWARDED_FOR'], $unknown)){
$arr = explode(',', $_SERVER['HTTP_X_FORWARDED_FOR']);
foreach($arr as $ip){
$ip = trim($ip);
if ($ip != 'unknown'){
$realip = $ip;
break;
}
}
}else if(isset($_SERVER['HTTP_CLIENT_IP']) && !empty($_SERVER['HTTP_CLIENT_IP']) && strcasecmp($_SERVER['HTTP_CLIENT_IP'], $unknown)){
$realip = $_SERVER['HTTP_CLIENT_IP'];
}else if(isset($_SERVER['REMOTE_ADDR']) && !empty($_SERVER['REMOTE_ADDR']) && strcasecmp($_SERVER['REMOTE_ADDR'], $unknown)){
$realip = $_SERVER['REMOTE_ADDR'];
}else{
$realip = $unknown;
}
}else{
if(getenv('HTTP_X_FORWARDED_FOR') && strcasecmp(getenv('HTTP_X_FORWARDED_FOR'), $unknown)){
$realip = getenv("HTTP_X_FORWARDED_FOR");
}else if(getenv('HTTP_CLIENT_IP') && strcasecmp(getenv('HTTP_CLIENT_IP'), $unknown)){
$realip = getenv("HTTP_CLIENT_IP");
}else if(getenv('REMOTE_ADDR') && strcasecmp(getenv('REMOTE_ADDR'), $unknown)){
$realip = getenv("REMOTE_ADDR");
}else{
$realip = $unknown;
}
}
$realip = preg_match("/[\d\.]{7,15}/", $realip, $matches) ? $matches[0] : $unknown;
return $realip;
}
function GetIpLookup($ip = ''){
if(empty($ip)){
$ip = GetIp();
}
$res = @file_get_contents('http://int.dpool.sina.com.cn/iplookup/iplookup.php?format=js&ip=' . $ip);
if(empty($res)){ return false; }
$jsonMatches = array();
preg_match('#\{.+?\}#', $res, $jsonMatches);
if(!isset($jsonMatches[0])){ return false; }
$json = json_decode($jsonMatches[0], true);
if(isset($json['ret']) && $json['ret'] == 1){
$json['ip'] = $ip;
unset($json['ret']);
}else{
return false;
}
return $json;
}
$ipInfos = GetIpLookup('123.125.114.144'); //.com IP地址
var_mp($ipInfos);
使用了新浪的开放API
㈤ php屏蔽ip问题！！！
<?phpfunction check_ip($range,$ip='') {if($ip =='') $ip = getenv("REMOTE_ADDR");if ($ip == "127.0.0.1") return 1;$result = 1;if (ereg("([0-9]+).([0-9]+).([0-9]+).([0-9]+)/([0-9]+)",$range,$regs)) {$ipl = ip2long($ip);$rangel = ip2long($regs[1] .

㈥ php怎么记录访问者ip并生成日志
php获取访问者IP地址汇总
在很我的时候我们需要得到用户的真实IP地址，例如，日志记录，地理定位，将用户信息，网站数据分析等,其实获取IP地址很简单$_SERVER[\'REMOTE_ADDR\']就可以了。下面我们就来给大家汇总一下常用的几种获取IP地址的方法。
//方法1：
$ip = $_SERVER["REMOTE_ADDR"];
echo $ip;
//方法2：
代码如下:
$user_IP = ($_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 $onlineip;
//方法6：
print "您的IP地址是：";
if(!empty($_SERVER["HTTP_CLIENT_IP"])){
$cip = $_SERVER["HTTP_CLIENT_IP"];
}
elseif(!empty($_SERVER["HTTP_X_FORWARDED_FOR"])){
$cip = $_SERVER["HTTP_X_FORWARDED_FOR"];
}
elseif(!empty($_SERVER["REMOTE_ADDR"])){
$cip = $_SERVER["REMOTE_ADDR"];
}
else{
$cip = "无法获取！";
}
print $cip;
保存TEXT中
<?php
$ip = $_SERVER['REMOTE_ADDR'];
$time = gmdate("H:i:s",time()+8*3600);
$file = "123.txt" ;
$fp=fopen ("123.txt","a") ;
$txt= "$ip"."----"."$time"."\n";
fputs($fp,$txt);
?>
㈦ PHP正则 IP
<?php
$ip2="192.168.0.23";
$num=preg_match("/192.168.0.d{1,3}/",$ip2,$match);
var_mp($num);
var_mp($match);
?>
㈧ PHP实现代理IP
“代理IP”现在有很多种的，就是软件改IP的。
软件上有很多IP点提供给使用者切换的
在电脑上安装IP转换器，
在IP软件上选择不同的IP点连接就可以了的。
推荐软件。可找到类似软件的。
全国大多数城市（数百万IP点任意切换）
希望可以帮到你。多少电脑多可以使用的。
㈨ PHP如果获取IP地址
function getIP() {
if (@$_SERVER["HTTP_X_FORWARDED_FOR"])
$ip = $_SERVER["HTTP_X_FORWARDED_FOR"];
else if (@$_SERVER["HTTP_CLIENT_IP"])
$ip = $_SERVER["HTTP_CLIENT_IP"];
else if (@$_SERVER["REMOTE_ADDR"])
$ip = $_SERVER["REMOTE_ADDR"];
else if (@getenv("HTTP_X_FORWARDED_FOR"))
$ip = getenv("HTTP_X_FORWARDED_FOR");
else if (@getenv("HTTP_CLIENT_IP"))
$ip = getenv("HTTP_CLIENT_IP");
else if (@getenv("REMOTE_ADDR"))
$ip = getenv("REMOTE_ADDR");
else
$ip = "Unknown";
return $ip;
}
㈩ 为什么php获取ip显示::1
php自带函数获取ip地址函数
$_SERVER['SERVER_ADDR']
