Is it possible to create subdomains using php

[GUIR]

Hi,

I d like to know about the possibility of creating subdomains using php . Even an alternative would help until it helps to have the url format, http://subDomainOrAlias.domain.com

The answer is probably yes.

Do you want a PHP script that will update DNS records for you? Or, do you want a PHP script that will "forward" HTTP requests to the appropriate files/scripts based on the HTTP Host header?

If you're looking for the 1st option ... umm ... find a DNS service with a nice API and let us know how it turns out

If you're looking for the 2nd option, see the HTTP_HOST environment variable: http://www.php.net/manual/en/reserve...les.server.php


EDIT: In regards to the 2nd option, the assumption is that you've set up a wildcard host: *.yourdomain.com A <your apache server's IP>

Set up a wildcard host -- ask your hosting provider for help with their DNS control panel if you're not sure how to do this. And then start with something like this:

<?php
$valid_hosts = array(
  'host1',
  'host2',
  'host3'
);

if (in_array($_SERVER['HTTP_HOST'], $valid_hosts)) {
  require($_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI']);
} else {
  require('404.inc');
}
?>

Make sense?
