@so_is_thisNov 02.2006 — If it is the host name for the current document which you want, then you can use this:

$_SERVER["HTTP_HOST"]

The protocol being used is found here:

$_SERVER["SERVER_PROTOCOL"]

@bokehNov 02.2006 — please suggest me about this. bye[/QUOTE]So what is supposed to happen if there is no trailing slash. And why are you using the "[I]s[/I]" flag? A domain shouldn't have line feeds in it.

@martin_arickyNov 03.2006 — This can be used to get the domain from url.

$url = "http://www.search.com/abcd.html";

$parts = parse_url($url);

echo $parts['scheme'] eg: http://

echo $parts['host']; eg: www.search.com // domain name

echo $parts['path']; eg : abcd.html
