How does PHP get all the IPs between IP ranges?

Let's use the for loop, for example

for ($ii = 0; $ii <256; $ii++)echo "".$ii;

Hope it helps!

Your computer is connected to the router, which is the local loopback address, and the online test is the public IP address, and the local server is the server, and the server address is.

Don't tell me that you want to get access to the customer's external IP in the local test environment...

You put ** on the server of the external network, and then access the external network ** to get your external IP.

if(getenv( "http_client_ip ")) elseif(getenv( "http_x_forwarded_for ")) else If you intentionally hide, you can't get it.

The easiest way to get an IP address is an example.

reip=$_server["remote_addr"];

echo $reip;

PHP tutorial algorithm to get IP.

if(getenv(http_client_ip)) elseif(getenv(http_x_forwarded_for)) elseif(getenv(remote_addr)) else

echo $onlineip;

function getip_out()

if (!empty($_server[http_x_forwarded_for]))

for ($i = 0; $i < count($ips); i++)

return ($ip ? ip : server[remote_addr]);

echo getip_out();

PHP algorithm to get IP, used? expression.

user_ip = ($server["http_via"]) server["http_x_forwarded_for"] :server["remote_addr"];

user_ip = ($user_ip) ?user_ip : server["remote_addr"];

Hope it will help you.

Use this function to function user realip() elseif (getenv('http_x_forwarded_for'))

elseif (getenv('remote_addr'))else

return $ip;

Happy programming

Simple acquisition:

ip = $_server["remote_addr"];

echo $ip;

Or better with this method:

function getip()

Obtain the real client IP address

function realip(){

if(getenv('Let's get the http client ip'))ip=getenv('http_client_ip');

elseif(getenv('deficit http x forwarded for'))

ip=getenv('http_x_forwarded_for');

elseif(getenv('remote_addr'))ip=getenv('remote_addr');

else{ip=$http_server_vars['remote_addr'pin slippery land];

return $ip;

That's it: $server['remote_addr']

Perfecting the point can do this:

if (!empty($_server['http_client_ip']))elseif (!empty($_server['http_x_forwarded_for']))else

1. Remote Addr The IP address of the user's computer that is browsing the current page.

2. http x forwarded for the gateway of the user's computer browsing the current page.

The IP address of the client

In PHP, use the remote addr to get the client's IP address, but if the client is using a server to access, it will get the server's IP address, not the actual client IP address.

In order to get the real IP address of the client through the server, you need to use http x forwarded for to read it.

However, it should be noted that not every server can use HTTP x Forwarded for to read the real IP of the client, and some of them still read the IP of the server using this method.

Another thing to note is that if the client is not accessed through the server, then the value retrieved by HTTP x forwarded for will be empty.
