reading subdomain

[tolkienarda]

hi all
i have a wildcard subdomain that will redirect all subdomains to one page. this page is a php script that will read the what subdomain they entered and if it is valid it will redirect to the apporiate page and if not it will go the the home page. the reason i am doing this is because of a client who apparently has major intelligence issues. but the problem is that i don't know how to get the full url they entered in.
'http://subdomain.dumbc lient.com' the script is realy quite simple but i can't get that url and it is probaly some function that i just can't find below is the code that will process that so you can understand what i am doing a little better.

[PHP]
<?php
$a = 'http://subdomain.yours ite.com'; //will need the function to get the domain here
$sub = explode('.', $a);
$new_sub = explode('/', $sub[0]);


echo '<pre>';
echo var_dump($new_s ub);
echo '</pre>';
//do weird stuff with $new_sub[2]
?>
[/PHP]

thanks for all past present and future help

hi all
i found a function that will work

for all those who want to use it here you go

[PHP]
function selfURL()
{
$s = empty($_SERVER["HTTPS"]) ? '' : ($_SERVER["HTTPS"] == "on") ? "s" : "";
$protocol = strleft(strtolo wer($_SERVER["SERVER_PROTOCO L"]), "/").$s;
$port = ($_SERVER["SERVER_POR T"] == "80") ? "" : (":".$_SERVE R["SERVER_POR T"]);
return $protocol."://".$_SERVER['SERVER_NAME'].$port.$_SERVER['REQUEST_URI'];
}
function strleft($s1, $s2)
{
return substr($s1, 0, strpos($s1, $s2));
}
[/PHP]

and have a var = selfURL()
and it works perfectly

thanks

eric
