[SOLVED] I need to extract the domain name out of the hostname?

[oni-kun]

Hello. I have a script which currently uses..

$fullhost = gethostbyaddr($ip);

 

To get the host and it returns usually something long like.. d11.22.33.44.bschi.host.com ..

 

I use

$host = preg_replace("/^[^.]+./", "*.", $fullhost);

and it seems make it.. "*.bschi.host.com" but I just want.. "host.com"

 

How do I do this? I tried for hours last night to use strchr and strrpos etc but it always game out wrong.. how to I ignore everything before host.tld?

 

Thank you! This is not an important application, so it can be basic..

try this

<?php
$url="d11.22.33.44.bschi.host.com";
preg_match("/^(http:\/\/)?([^\/]+)/i",$url, $matches);
$host = $matches[2]; 
preg_match("/[^\.\/]+\.[^\.\/]+$/", $host, $matches);
echo $matches[0];
?>

<?php
$url="d11.22.33.44.bschi.host.com";
preg_match("/^(http:\/\/)?([^\/]+)/i",$url, $matches);
$host = $matches[2]; 
preg_match("/[^\.\/]+\.[^\.\/]+$/", $host, $matches);
echo $matches[0];
?>

 

Works perfect! Thanks. I can now put a [whois] autogenerated link beside the host, it's useful for my project.
