PHP: Print string depending on domain or subdomain

I need a PHP-script that shows/prints different strings depending on whether the current document is on a domain or subdomain. If it is on a subdomain it is to print different string depending on the first letter (a-z), if not a-z then yet another string is to be printed.

The script must be tolerant to whether "www" is used or not.


I need it ASAP. $10 thru paypal.

 

I am interested !
PM me with all the details !

 

i am not exper but i think this can be done by something like this

$exploded= explode (".", $array);

Code (markup):

then u need to add something which will automatically print out if the $explode[3] exists or not?

if it exists then it means that it is a subdomain otherwise domain

 

# Find subdomain
preg_match('@^(www\.)?(.*)yourdomain\.com$@i',$_SERVER['HTTP_HOST'],$tmp);
$sub = empty($tmp[2]) ? false : $tmp[2];
unset($tmp);

if ( $sub ) {
  # Subdomain - extract first character
  $first = substr($sub,0,1);
  if ( ctype_alpha($first) )
    # First char is A-Z
    include 'subdomaina-z.html';
  else
    # First char is not A-Z
    include 'subdomainnota-z.html';
} else {
  # Main domain
  include 'maindomain.html';
}

PHP:

Untested but should be something along those lines.
