script read blocklist ips and restrict page
Hi
This php code try to read Ips from blacklist.txt file and then restrict access to page from visitors with same IP in blacklist.txt
[CODE]<?php
if ( !file_exists(‘blacklist.txt’) ) {
$deny_ips = array(
‘127.0.0.1’,
‘192.168.1.1’,
‘83.76.27.9’,
‘192.168.1.163’
);
} else {
$deny_ips = file(‘blacklist.txt’);
}
// read user ip adress:
$ip = isset($_SERVER[‘REMOTE_ADDR’]) ? trim($_SERVER[‘REMOTE_ADDR’]) : ”;
// search current IP in $deny_ips array
if ( (array_search($ip, $deny_ips))!== FALSE ) {
// address is blocked:
echo ‘Your IP adress (‘.$ip.’) was blocked!’;
exit;
}
?>
But
-This code can’t read blacklist.txt if it has been tons thousands IP listed , how can fix it and make it available to read big list
and
– How can i make script to read Ips from an external URL for get low load in CPU . for example blacklist be on another server and address :[url]http://domain2.com/blacklist.txt

@NogDogJan 02.2017 — #Well, one approach:[code=php]
$pdo = new PDO($dsn, $user, $pwd); // read the documentation
$stmt = $pdo->prepare("SELECT COUNT(*) FROM table_name WHER IP_ad = :ip");
$stmt->bind_param(':ip', $ip_address);
$stmt->execute();
if($stmt->fetchColumn() > 0) {
// match found
}
[/code]
