I would like to get the host name of any url for example if i've the following url

$url = "http://www.google.com";

then i want to get only google what is after dot . and before extension dot . so that it can be applied for all types of urls.

so the results should be google ! i think this might needs regex or somehow any idea how to do it , Thanks.

You can try

echo __extractName("http://google.com"); 
echo __extractName("http://office1.dept1.google.com");
echo __extractName("http://google.co.uk");


function __extractName($url)
{
  $domain = parse_url($url , PHP_URL_HOST);
  if (preg_match('/(?P<domain>[a-z0-9][a-z0-9\-]{1,63}\.[a-z\.]{2,6})$/i', $domain, $list)) {
    return substr($list['domain'], 0,strpos($list['domain'], "."));
  }
  return false;
}

Output 

google
google 
google

You should have a look at PHP's parse_url() function which returns an associative array of the various components that constitute a URL. 

$url = "http://www.google.com";
print_r(parse_url($url));

Will echo the following array. 

Array ( [scheme] => http [host] => www.google.com )

The above function will just give you a start. Check into the following Stackoverflow archives on how to take it up from here.

  • Note that you can also pass `PHP_URL_HOST` as the second parameter, and it will just return the hostname instead of an array. – Waleed Khan Oct 02 '12 at 11:31
  • well based on your idea and very amazing archives, i will use 'explode' and then will results an array where i can print only the exact part of url i want. ~ thanks – Reham Fahmy Oct 02 '12 at 11:34
  • for sure. Next time around, ensure that you "google" :) Lest you'll either be downvoted or your question will be closed. – verisimilitude Oct 02 '12 at 11:36
