php Get visitor IP address summary

Sometimes we need to get the user’s real IP address, for example, logging, geolocation, user information, website data analysis, etc. In fact, obtaining the IP address is very simple, just use the global variable $_SERVER[\'REMOTE_ADDR\'].

Let’s summarize some commonly used methods for obtaining IP addresses.

//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 : $_SERVER[&#39;REMOTE_ADDR&#39;]);
}
echo getRealIp();
//方法4:
if ($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(&#39;HTTP_CLIENT_IP&#39;)) {
$onlineip = getenv(&#39;HTTP_CLIENT_IP&#39;);
} elseif(getenv(&#39;HTTP_X_FORWARDED_FOR&#39;)) {
$onlineip = getenv(&#39;HTTP_X_FORWARDED_FOR&#39;);
} elseif(getenv(&#39;REMOTE_ADDR&#39;)) {
$onlineip = getenv(&#39;REMOTE_ADDR&#39;);
} else {
$onlineip = $HTTP_SERVER_VARS[&#39;REMOTE_ADDR&#39;];
}
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;

$time = gmdate("H:i:s",time()+8*3600);
$file = "123.txt" ;
$fp=fopen ("123.txt","a") ;
