Retrive client's ip address

[John]

My script is:

<?
$host = gethostbyaddr($REMOTE_ADDR);

print "Your host name is $host ($REMOTE_ADDR).";
?>

but when I run the script I get this:

Notice: Undefined variable: REMOTE_ADDR in E:\Abyss Web Server\htdocs\test.php on line 11

Notice: Undefined variable: REMOTE_ADDR in E:\Abyss Web Server\htdocs\test.php on line 13
Your host name is John ().


Please help me, thanks

Use $_SERVER["REMOTE_ADDR"].
