PHP how to get local IP of system

Question

I need to get local IP of computer like 192.*.... Is this possible with PHP?

I need IP address of system running the script, but I do not need the external IP, I need his local network card address.

Answer 1

try this (if your server is Linux):

$command="/sbin/ifconfig eth0 | grep 'inet addr:' | cut -d: -f2 | awk '{ print $1}'";
$localIP = exec ($command);
echo $localIP;

Answer 2

If you are in a dev environment on OS X, connected via Wifi:

echo exec("/sbin/ifconfig en1 | grep 'inet ' | cut -d ' ' -f2");

Answer 3

$_SERVER['REMOTE_ADDR']

• PHP_SELF Returns the filename of the current script with the path relative to the root

• SERVER_PROTOCOL Returns the name and revision of the page-requested protocol

• REQUEST_METHOD Returns the request method used to access the page

• DOCUMENT_ROOT Returns the root directory under which the current script is executing

Answer 4

This is an old post, but get it with this:

function getLocalIp()
{ return gethostbyname(trim(`hostname`)); }

For example:

die( getLocalIp() );

Found it on another site, do not remove the trim command because otherwise you will get the computers name.

BACKTICKS (The special quotes): It works because PHP will attempt to run whatever it's between those "special quotes" (backticks) as a shell command and returns the resulting output.

gethostbyname(trim(`hostname`));

Is very similar (but much more efficient) than doing:

$exec = exec("hostname"); //the "hostname" is a valid command in both windows and linux
$hostname = trim($exec); //remove any spaces before and after
$ip = gethostbyname($hostname); //resolves the hostname using local hosts resolver or DNS

Answer 5

hostname(1) can tell the IP address: hostname --ip-address, or as man says, it's better to use hostname --all-ip-addresses

Answer 6

$localIP = gethostbyname(trim(exec("hostname")));

I tried in Windows pc and Its worked and also think that Will work on Linux to.
