find domain name dynamically

[jackvull]

I have 2 registered domains, which point to the same web root folder.
I would like to display a different logo image depending on which domain the user requested.
Is it possible to find the domain name with PHP?

I believe $_SERVER['HTTP_HOST'] should do it.

this will do it

<?
if (strpos(getenv('SERVER_NAME'), 'domain1.com')!==false) {
echo "<img src='1.jpg'>";
} elseif (strpos(getenv('SERVER_NAME'), 'domain2.com')!==false) {
echo "<img src='2.jpg'>";
};
?>
