Need to remove www from $_SERVER['HTTP_HOST'] how?

Question

I need to remove www from the string given by $_SERVER['HTTP_HOST']

How can I do that in PHP?

Answer 1

$server_name = str_replace("www.", "", $_SERVER['HTTP_HOST']);

That should do the trick...

Answer 2

if (substr($_SERVER['HTTP_HOST'], 0, 4) == 'www.') {
    $domain = substr($_SERVER['HTTP_HOST'], 4);
} else {
    $domain = $_SERVER['HTTP_HOST'];
}
