Obtain current machine IP using PHP

richie

Does php have a function for obtaining the ip address of the machine it is running on?

Microsoft windows does the same thing using WINIPCFG.

Thanks.

Richie.

use $_SERVER['REMOTE_ADDR'] variable.

Jayant,

What I need is the IP address of the machine that php is running on, not the ip address of a visitor to the website.

'REMOTE_ADDR'
The IP address from which the user is viewing the current page.

If you want to find an IP address given the host name try PHP's gethostbyname($hostname) function.

To find multiple IP address you could use the function gethostbyname1($hostname).

To get the $hostname automatically...in case you don't know:

gethostbyname($HTTP_SERVER_VARS["SERVER_NAME"])

Well your question is already answered now.

This gives me a lesson, never do things when you are half awake. One tends to overlook somethings

This is a piece of code I use for test.

Oops, sorry for previous post: I was missing THE POINT.

You can get the SERVER IP address using the function gethostbyname() with SERVER_NAME

Ciao. Michele.

echo "<td>server IP address</td><td><b>".gethostbyname($SERVER_NAME)."</b></td></tr>" ;

Thanks everybody for your help.

gethostbyname($SERVER_NAME) did it.

Richie.
