Getting current user's IP address

asgsoft · Mar 4, 2006

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:

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

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

?>

I hope somebody finds it helpful.

Thanks for the information...I was looking for such a info to be used with a Quiz PHP Script!

I personally uses JS for that :D But I guess PHP overcomes it in simplicity

Slightly different method, same info:

Code:

 <?php


   echo "<html><head><title>lifted from www.scanmybrowser.com</title></head>";
   echo "<body><h1>A few request header variables:</h1>";
   echo "HTTP_REFERER=".getenv("HTTP_REFERER")."<br>";
[COLOR=DarkOrange]   echo "REMOTE_ADDR=".getenv("REMOTE_ADDR")."<br>";
[/COLOR]   echo "HTTP_USER_AGENT=".getenv("HTTP_USER_AGENT")."<br>";
   echo "HTTP_ACCEPT=".getenv("HTTP_ACCEPT")."<br>";
   echo "HTTP_ACCEPT_LANGUAGE=".getenv("HTTP_ACCEPT_LANGUAGE")."<br>";
   echo "HTTP_ACCEPT_CHARSET=".getenv("HTTP_ACCEPT_CHARSET")."<br>";
   echo "HTTP_ACCEPT_ENCODING=".getenv("HTTP_ACCEPT_ENCODING")."<br>";
   echo "</body></html>";

?>
