Question

I’ve got a site that is pretty customized, set up on subdomains; sitename.domain.com and it’s got some pages (that are the same for ALL subdomains) sitename.domain.com/this-page. Every single site has “/this-page”.

We’ve got someone interested in using some of the stuff we’ve developed, but they are MARRIED to using subdirectories; domain.com/sitename which would, of course, have domain.com/sitename/this-page as well.

My question is, I’ve got some code

$sN = 'http://www.' . $_SERVER['HTTP_HOST'];
$PAGE = $sN . '/this-page/';

• but of course this does not work for the subdirectory install (it looks for domain.com/this-page/ instead of domain.com/sitename/this-page

is there a way I can differentiate between subdomains and subdirectories?

$setup = "GET THE HOME PAGE, REGARDLESS OF SETUP"
if($setup ( CONTAINS www.X.X.com)) { //do the code above }
else if ($setup ( CONTAINS www.X.com/X)) { //do different code }

[EDIT] Tried the solution from http://www.php.net/manual/en/reserved.variables.server.php#100881 but didn’t work for me, so I did this:

<?php
$sitename = 'sitename';
if (strpos($_SERVER['HTTP_HOST'],$sitename)!==false){
    echo 'you are in http://'.$_SERVER['HTTP_HOST'] . '/'; 
 // you are in http://sitename.domain.com/
} else {
    $path = explode('/',$_SERVER['PHP_SELF']);
    unset ($path[count($path)-1]);
    echo 'you are in http://' . $_SERVER['HTTP_HOST'] . implode('/',$path) .'/'; 
 // you are in http://www.domain.com/sitename/
}
?>
