将域重定向到不同的.php文件

Question

I have a webhoster which does not serve Name aliases for my DNS Domain. I have 2 different domains. Both should be redirected to different targets (e.g. /index.php , /abc/index2.php), but at the same root-server.

How could i use both domains with one server with PHP or a tool (ubuntu)?

Thanks.

You should check the host header HTTP_HOST of the request to know on which domain the request is.

if (strpos($_SERVER["HTTP_HOST"], "domaina.com") !== false) {
  header('Location: '.$urldomaina);
}
else if (strpos($_SERVER["HTTP_HOST"], "domainb.com") !== false)
{
    header('Location: '.$urldomainb);
}
