How can I convert URLS like:

https://danielabruña.com/
https://fagualópez.com/
https://laconspiracióndelcastellano.com/

to their UTF-8 encoding variants?

It depends on the encoding of your text editor, but those are likely to be already UTF-8. You surely mean ASCII, as used by internationalized domain names.

First you need to extract the raw domain name with e.g. parse_url(), because IDN only applies to domains. Then you can use idn_to_ascii() the get the pure 7-bit ASCII encoding:

$urls = [
    'https://danielabruña.com/',
    'https://fagualópez.com/',
    'https://laconspiracióndelcastellano.com/',
];

foreach ($urls as $url) {
    $domain = parse_url($url, PHP_URL_HOST);
    var_dump($domain, idn_to_ascii($domain));
}

string(17) "danielabruña.com"
string(23) "xn--danielabrua-beb.com"
string(15) "fagualópez.com"
string(21) "xn--fagualpez-b7a.com"
string(32) "laconspiracióndelcastellano.com"
string(38) "xn--laconspiracindelcastellano-ctc.com"

For this to work, you need to set your text editor to save files as UTF-8. Otherwise, you'll need to do additional conversions with e.g. mb_convert_encoding().

Rebuilding the original URL is a bit trickier, but also out of the scope of the question. You can use a dedicated URL handling library or string replace functions.

With "utf8_encode":

echo(utf8_encode("https://danielabruña.com/")); 
echo(utf8_encode("https://fagualópez.com/")); 
echo(utf8_encode("https://laconspiracióndelcastellano.com/")); 

Result:

https://danielabruña.com/

https://fagualópez.com/
