Method 2:

The code is as follows:

$user _ip = ($_server["Http_via"])? $_server["Http_x_forwarded_for"]: $_server["REMOTE_ADDR"];

$user _ip = ($user _ip)? $user _ip: $_server["REMOTE_ADDR"];

echo $user _ip;

Method 3:

?

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

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 ). ", $ips [$i])) {$ip = $ips [$i]; break;}} Return ($ip $ip: $_server[' remote_addr ')); Echo Getrealip ();

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_f or "); } elseif (getenv ("Http_client_ip")) {$ip = getenv ("Http_client_ip");} elseif (Getenv ("REMOTE_ADDR")) {$ip = getenv ("REM Ote_addr "); else {$ip = "Unknown";} Echo $ip;

Method 5:

?

1 2 3 4 5 6 7 8 9 10

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;

Method 6:

?

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

Print "Your IP address is:"; if (!empty ($_server["Http_client_ip")) {$cip = $_server["Http_client_ip"]; ElseIf (!empty $_server[ Forwarded_for "])) {$cip = $_server[" Http_x_forwarded_for "]; ElseIf (!empty ($_server[" REMOTE_ADDR "])) {$cip = $_server ["REMOTE_ADDR"]; } else{$cip = "cannot be obtained!" "; } Print $cip;

The above mentioned is the entire content of this article, I hope to learn PHP can help you.
