Below the short php function to parse a URL and return just the domain name without using regex.

function getDomain($url)
{
$exten="";
$explode = explode(".", $url);
$firstpart = $explode[0];
$secondpart = $explode[1];
if(!strstr($url,"www")) // for url have www
{
$secondpart=explode("/",$secondpart);
$secondpart=$secondpart[0];
}
else // not have www
{
$thirdpart = $explode[2];
$thirdpart = explode("/", $thirdpart);
$exten = ".".$thirdpart[0];
}

return $firstpart.".".$secondpart.$exten;
}

$domain=getdomain("http://www.qualitypointtech.net/NewsFeed/view_allfeed.php");
$domain1=getdomain("http://qualitypointtech.net/NewsFeed/view_allfeed.php");

the first one return the 'http://www.qualitypointtech.net' and second one return the 'http://qualitypointtech.net' as output.

so we need not worry about whether the url have www or not.

In the above code it return domain name with http:// and http://www.

I needed only host name like this, 'qualitypointtech.net' if my input is anything. I used below code getting this.

While executing the above code we got the error message as getHostName() in line23

This error message will display, based on the server settings. So to resolve this problem we have changed the function name now it was working fine.
