Remove dots from dot com's

[mkelley]

I have the code below and it produces

 

<title>M.Kelley</title>
<link rel='stylesheet' href='mkelley.com.css' type='text/css' />

 

<?php

$new_domain = $_SERVER['HTTP_HOST'];
switch ($new_domain){
case "mkelley.com":
	echo "<title>M.Kelley</title>";
	echo "<link rel='stylesheet' href='$new_domain.css' type='text/css' />";
	break;	
case "www.mkelley.com":
	echo "<title>M.Kelley</title>";
	echo "<link rel='stylesheet' href='$new_domain.css' type='text/css' />";
	break;

}


?>

 

I'm very very new to regex, how can I remove the . from domain.com or from www.domain.com ? I'd like it to produce

 

<title>M.Kelley</title>
<link rel='stylesheet' href='mkelleycom.css' type='text/css' />

This is one way:

$text = preg_replace('/\.(?!css)/', '', $text);

Assuming you're just dealing with the form 'foo.com.css'
