current user ip

[anilshiv]

While looking in the PHP predefined variables i found an intersting one: $_ENV["REMOTE_ADDR"]. what this does is it gives the current IP of the person viewing your site. This is quite good if you are making a poll for a intranet where each user has their own username.

Have a look at this and tell me what you think.

PHP Code:

PHP Code:

<?php
$ip = $_ENV["REMOTE_ADDR"]; //set variable

echo $ip; //show the value of the variable

?>

I hope somebody finds it helpful
