There is a link: http://www.site.com

Please tell me how to cut a subdomain from this address.

Ie any link http: // (*) .site.com, turned into site.com

http://site.com = site.com http://blocg.site.com = site.com http://forum.site.com = site.com http://www.site.com = site.com

    IMHO without regulars will be faster:

    function get_subdomain($url) { $segments = parse_url($url); return current(explode('.', $segments['host'], 2)); } echo get_subdomain('http://blocg.site.com'); //blocg
