php gets visitor IP address summary

　php gets 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, getting the IP address is very simple, just $_SERVER['REMOTE_ADDR'] . Below we will summarize for you some commonly used methods of obtaining IP addresses.

//Method 1:

1 2	$ip = $_SERVER["REMOTE_ADDR"]; echo $ip;

$ip = $_SERVER["REMOTE_ADDR"];

echo $ip;

//Method 2:

The code is as follows:

$user_IP = ($_SERVER["HTTP_VIA"]) ? $_SERVER["HTTP_X_FORWARDED_FOR"] : $_SERVER["REMOTE_ADDR"];

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();

　$user_IP = ($user_IP) ? $user_IP : $_SERVER["REMOTE_ADDR"];

echo $user_IP;

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 ;

//Method 3: 　?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

//Method 4: 　?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29

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;

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;

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：　　?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

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;
