php проверь, занесен ли ip-адрес пользователя в черный список, и заблокируй его из моего приложения.

Question

php проверь, занесен ли ip-адрес пользователя в черный список, и заблокируй его из моего приложения.

Я хочу написать функцию php, которая берет IP-адрес пользователя, проверяет его по известным черным спискам и перенаправляет пользователей с ip-адресов из черного списка на страницу по умолчанию «Access Forbidden». Я хочу разрешить доступ к моей домашней странице только пользователям с IP-адресов, которые не попали в черный список. Кто-нибудь может помочь? Вот что у меня так далеко.

<?php

$ip=$_SERVER["REMOTE_ADDR"];

function flush_buffers()
{
ini_set('output_buffering','on');
ini_set('zlib.output_compression', 0);
ini_set('implicit_flush',1);
ob_implicit_flush();

echo ("<html><head><head><body>");
for($i=0;$i<20;$i++) {
echo $i;
echo str_repeat(" ", 500);
ob_flush();
flush();
sleep(1);
}
}

настоящая проблема в том, сколько времени это займет.

Сделано несколько изменений, чтобы показать, что я имею в виду

среднее время 60 секунд, и это долго ждать на сайте
