Topic awaiting preservation: PHP: Domain-based redirection via an array...

I'm trying to create a page that will redirect users from a few different sites to a different page, and I'm having some trouble making it work for more than one page. Basically, here's what works for one page:

Before the DOCTYPE declaration:

<?php
	$comingFrom = $_SERVER['HTTP_REFERER'];
	$itWorked = "It worked, indeed!";
	$sitesArray = array("mydomain.com", "otherdomain1com", "otherdomain2.com");
?>

In the body:

<?php 
if(substr_count($comingFrom, 'mydomain.com')) {
	echo $itWorked;
} else {
	echo $comingFrom;
}
 ?>

The $comingFrom variable is there just to confirm that it works (for now). Later on, I'll replace that with the code to redirect folks to the other page.

You'll notice there's an array declared up at the top. What I want to do is call that array in place of 'mydomain.com' in the "body code". My question is, how can I do that?

Thanks.

<?php 
$from = parse_url($comingFrom);
$pattern = '#('.str_replace('.','\.',implode('|',$sitesArray)).')$#i';
if(preg_match($pattern,$from[host])) {
	echo $itWorked;
} else {
	echo $comingFrom;
}
 ?>

Tested and works.
