I would like to delete the URI, that is to say what follows from a URL, as in the example in the title of the question with PHP.
http://misitio.com/uri/uri/loquesea - > http://misitio.com
@ RobertoLeónOramas I am requesting a php sanitizer, not a rewrite htaccess rule.
@MrViKxD Returns the hostname in which the site is accessed, I need a sanitizer, that's not what I need.
You can use the array $ _SERVER
$_SERVER['SERVER_ADDR'];
$url = explode('/', $url);
$url = implode('/', array_slice($url, 0, 3));
If you want to extract the current domain, it would suffice:
$host = $_SERVER['HTTP_HOST']; //HTTP_HOST devuelve el dominio.com o www.dominio.com
$host = 'http://'.$host //Si quieres añadir http
If what you want is a function that from a url is left with the domain part:
$url = 'http://misitio.com/uri/uri/loquesea';
$parse = parse_url($url);
print $parse['host']; // devuelve misitio.com
print $parse['scheme'].'//'.$parse['host']; //devuelve http://misitio.com
You can find the parse_url($url) documentation here:
