Echo only a part of an URL (string)

I have an input field where the user can type an URL. He could type the URL in many different ways, for example:

No matter how he types it, I want to echo it like this: example.com

Only when it is an sub domain, then it should look like this: subdomain.example.com

How can I do this?

I allow myself to answer my own question:

$url = 'https://www.example.com/index.php';
$str = preg_replace('#^https?://|www.#', '', rtrim($url,'/'));
echo (strpos($str,'/') !== false) ? strstr($str, '/', true) : $str;

You can define $url however you want. The result is always example.com

Use parse_url() with the PHP_URL_HOST component as the second parameter:

$url = 'example.com/index.php';
if (preg_match("#https?://#", $url) === 0) {
    $url = 'http://'.$url;
}
echo parse_url($url, PHP_URL_HOST);

(I had some help from this answer to make sure there is always a protocol attached to the URL.)
