Get domain name from full URL

say someone enters a URL like this:

http://i.imgur.com/a/b/c?query=value&query2=value

And I want to return: imgur.com

not i.imgur.com

This is code I have right now

$sourceUrl = parse_url($url);
$sourceUrl = $sourceUrl['host'];

But this returns i.imgur.com

Check Simaple Code You can get host, subdomain, domain, extension

$urls = array("https://www.face.com","www.asdasd.asd","sasdas.com/asdas","sdfsdf.sdf","https://app.abcdlink.com/user/test/");

Function :-

function getDomainname($a)
{
   $r = "(?P<host>(?:(?P<subdomain>[\w\.]+)\.)?" . "(?P<domain>\w+\.(?P<extension>\w+)))";
   $r = "!$r!";// Delimiters
   preg_match($r, $a, $out);

// if you need only domain then return $out['domain'];
// if you need only host then return $out['host'];
// if you need only subdomain then return $out['subdomain'];
// if you need only extension then return $out['extension'];

// Full Data array
    return $out;

}

$urls = array_map('getDomainname', $urls);

OR

function getsingaldomainHost($a)
{
    $a = (substr($a, 0, 7) == "http://" || substr($a, 0, 8) == "https://") ?  $a : 'http://' . $a;
    $r = "/(?P<host>(?:(?P<subdomain>[a-z0-9][a-z0-9\-]{0,63}\.[a-z0-9]{0,62}))?(?P<domain>[a-z0-9][a-z0-9\-]{0,63}\.[a-z0-9]{0,62})(?P<extension>[a-z0-9][a-z0-9\-]{0,63}\.[a-z\.]{0,61}))$/i";
    $pieces = parse_url($a);
    if (isset($pieces['host'])) {
        $domain = substr($pieces['host'], 0, 4) == "www." ?  $pieces['host'] : 'www.' . $pieces['host'];
    } else {
        $domain = $pieces['path'];
    }

    if (preg_match($r, $domain, $regs)) {
        return substr($regs['host'], 0, 4) == "www." ? substr($regs['host'], 4) : $regs['host'];
    } else {
        if ($rr == 1) {
            return false;
        } else {
            return $a;
        }
    }
}
$urls = array_map('getsingaldomainHost', $urls);

The code below should be perfect for the job.

function get_domain($url){
  $charge = explode('/', $url);
  $charge = $charge[2]; //assuming that the url starts with http:// or https://
  return $charge;
}

echo get_domain('http://www.example.com/example.php');

Check the code below, it should do the job fine.

<?php

function get_domain($url)
{
  $pieces = parse_url($url);
  $domain = isset($pieces['host']) ? $pieces['host'] : $pieces['path'];
  if (preg_match('/(?P<domain>[a-z0-9][a-z0-9\-]{1,63}\.[a-z\.]{2,6})$/i', $domain, $regs)) {
    return $regs['domain'];
  }
  return false;
}

print get_domain("http://mail.somedomain.co.uk"); // outputs 'somedomain.co.uk'

?>

I have found a very useful library using publicsuffix.org, PHP Domain Parser is a Public Suffix List based domain parser implemented in PHP.

https://github.com/jeremykendall/php-domain-parser

 <?php 
 // this will do the job

 require_once '../vendor/autoload.php';

 $pslManager = new Pdp\PublicSuffixListManager();
 $parser = new Pdp\Parser($pslManager->getList());
 var_dump($parser->getRegistrableDomain('www.scottwills.co.uk'));
 ?>

string(16) "scottwills.co.uk"

You need package that using Public Suffix List. Yes, you can use string functions arround parse_url() or regex, but they will produce incorrect result in complex URLs.

I recomend TLDExtract for domain parsing, here is sample code:

$url = 'http://i.imgur.com/a/b/c?query=value&query2=value';

parse_url($url, PHP_URL_HOST); // will return 'i.imgur.com'

$extract = new LayerShifter\TLDExtract\Extract();
$result = $extract->parse($url);
$result->getFullHost(); // will return 'i.imgur.com'
$result->getSubdomain(); // will return 'i'
$result->getRegistrableDomain(); // will return 'imgur.com'
$result->getSuffix(); // will return 'com'

If you only want the domain name, try the following:

$domain = $_SERVER['SERVER_NAME'];

echo $domain;

use this:

$uri = "$_SERVER[REQUEST_URI]";<br>
print($uri);

Example:

http://exemple.com/?directory<br>
Result:
/?diretory

The command get the directory and not domain.
