How do I get the inner IP address in my webpage? Can be any language for designing a website (javascript,php,etc.). What I need to do actually, is to make a local web server, and to let the clients in the same wifi network to connect via its shown IP address(192.168.X.X) on a webpage. But I always get 127.0.0.1 in php instead of 192.168.X.X, any ideas?

    When you run your page on your localhost you always get your localhost IP: 127.0.0.1 If you upload it to another server you can see your WAN IP – zkanoca Mar 02 '13 at 11:12

I solved by the following code, getting the wireless local IP address(192.168.X.X):

$myIP = gethostbyname(trim(`hostname`));

// PHP < 5.3.0
$Local_IP = @gethostbyname(php_uname('n'));

// PHP >= 5.3.0
$Local_IP = @gethostbyname(getHostName());

You just have to read it in 

$ip = $_SERVER['SERVER_ADDR'];

If you want to know all data available in $_SERVER use:

print("<pre>\n");
print_r($_SERVER);
print("\n</pre>\n");

$_SERVER contains lots of useful informations. You may also want to check: 

$_SERVER['LOCAL_ADDR']

    the server is using localhost, so it won't get the expected ip by using **$_SERVER**, it return 127.0.0.1 to me. thanks anyway. – Jeffrey Neo Mar 02 '13 at 15:06
