PHP — API para Obter todos os Países

Olá Gente!

Quantas vezes não precisamos de dados de regiões, e temos que ficar buscando?

Para obter Países temos uma API Excelente:

https://restcountries.com/

Para obter todos os países basta fazer uma GET para:

https://restcountries.com/v3.1/all

Exemplo:

<?php
$curl 		= curl_init();

curl_setopt_array($curl, array(
CURLOPT_URL 				=> "https://restcountries.com/v3.1/all",
CURLOPT_RETURNTRANSFER 		=> true,
CURLOPT_MAXREDIRS 			=> 10,
CURLOPT_TIMEOUT 			=> 30,
CURLOPT_SSL_VERIFYHOST 		=> false,
CURLOPT_SSL_VERIFYPEER 		=> false
));

$response 	= curl_exec($curl);
$response2  = json_decode($response, true);

curl_close($curl);

foreach( $response2 as $RegResponse )
{
    
    var_dump($RegResponse);
    echo "\n\r";
    
}
?>

Iremos receber um array onde cada país vem em um elemento:
