PHP: Remove http://, http://www, https://, https:// from String and get the Domain name and TLD

I would like to create a function in PHP that removes all inputs like

http://
https://
http://www.
https://www.
http://xyz.

from a given domain name like

example.com

and returns an array like this:

'name' => 'example'
'tld' => 'com'

Any ideas how to do that?

Correct way for extracting real TLD is using package that operates Public Suffix List, only in this way you can correctly extract domains with two-, third-level TLDs (co.uk, a.bg, b.bg, etc.). I recomend use TLD Extract.

Here is sample code:

$extract = new LayerShifter\TLDExtract\Extract();

$result = $extract->parse('http://mail.yahoo.co.uk');
$result->getSubdomain(); // will return (string) 'mail'
$result->getHostname(); // will return (string) 'yahoo'
$result->getSuffix(); // will return (string) 'co.uk'

Try following regex:

(?:^|\s)(?:https?:\/\/)?(?:\w+(?=\.).)?(?<name>.*).(?<tld>(?<=\.)\w+)

See demo at https://regex101.com/r/lI2lB4/2

If you input is

www.google.com
mail.yahoo.com.in
http://microsoft.com
http://www.google.com
http://mail.yahoo.co.uk

Captured content will be:

MATCH 1
name       = `google`
tld        = `com`

MATCH 2
name       = `yahoo.com`
tld        = `in`

MATCH 3
name       = `microsoft`
tld        = `com`

MATCH 4
name       = `google`
tld        = `com`

MATCH 5
name       = `yahoo.co`
tld        = `uk`

I think you don't need to remove protocol, www or even subdomain, All you need is extracting name and tdl from the URL. So try this:

RegEx solution:

<?php

$url  = 'https://www.example.com#anchor';
$host = parse_url($url, PHP_URL_HOST);  // www.example.com
preg_match('/(\w+)\.(\w+)$/', $host, $matches);
$array_result = array ( "name" => $matches[1],
                        "tld"  => $matches[2] );
print_r($array_result);

Online Demo

Without RegEx:

<?php

$url  = 'https://www.example.com#anchor';
$host = parse_url($url, PHP_URL_HOST);  // www.example.com
$host_names = explode(".", $host);
$array_result = array ( "name" => $host_names[count($host_names)-2],
                        "tld"  =>  $host_names[count($host_names)-1] );
print_r($array_result);

Online Demo

/*
 Output:
 *    Array
 *    (
 *        [name] => example
 *        [tld] => com
 *    ) 
*/
