php获取当前电脑ip的六种常见方法代码

六种常见方法代码php获得ip地址
方法一：

<?php
function GetIP(){
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！";
}
return $cip;
}
echo GetIP();
?>

方法二：

<?php
error_reporting (E_ERROR | E_WARNING | E_PARSE);
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;
?>

方法三：

<?php
$iipp = $_SERVER["REMOTE_ADDR"];
echo $iipp ;
?>

方法四：

<?php
$user_IP = ($_SERVER["HTTP_VIA"]) ? $_SERVER["HTTP_X_FORWARDED_FOR"] : $_SERVER["REMOTE_ADDR"];
$user_IP = ($user_IP) ? $user_IP : $_SERVER["REMOTE_ADDR"];
echo $user_IP
?>

方法五：

<?php
function get_real_ip()
{
$ip=false;
if(!empty($_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 get_real_ip();
?>

方法六：

<?php
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;
?>

PHP 获取当前的域名和本地IP

        <?
    //获取当前的域名:
    echo $_SERVER['SERVER_NAME'];
    //获取来源网址,即点击来到本页的上页网址
    echo $_SERVER["HTTP_REFERER"];
    $_SERVER['REQUEST_URI'];//获取当前域名的后缀
    $_SERVER['HTTP_HOST'];//获取当前域名
    dirname(__FILE__);//获取当前文件的物理路径
    dirname(__FILE__)."/../";//获取当前文件的上一级物理路径
    ?>

   <?
    function get_client_ip()
    {
    if ($_SERVER['REMOTE_ADDR']) {
    $cip = $_SERVER['REMOTE_ADDR'];
    } elseif (getenv("REMOTE_ADDR")) {
    $cip = getenv("REMOTE_ADDR");
    } elseif (getenv("HTTP_CLIENT_IP")) {
    $cip = getenv("HTTP_CLIENT_IP");
    } else {
    $cip = "unknown";
    }
    return $cip;
    }
    echo "你的IP地址是：".get_client_ip();
    ?>
