This PHP 5.4+ library provides IP filtering features.
A lot of filters can be used.
It is also possible to customize the error handling.
Add this line in your composer.json :
{
"require": {
"tramtro/m6web-firewall": "^1.0"
}
}Update your vendors :
$ composer update tramtro/m6web-firewall
use nguyenanhung\Component\Firewall\Firewall;
$whiteList = array(
'127.0.0.1',
'192.168.0.*',
);
$blackList = array(
'192.168.0.50',
);
$firewall = new Firewall();
$connAllowed = $firewall
->setDefaultState(false)
->addList($whiteList, 'local', true)
->addList($blackList, 'localBad', false)
->setIpAddress('195.88.195.146')
->handle()
;
if (!$connAllowed) {
http_response_code(403); // Forbidden
exit();
}In this example, only IPs starting with 192.168.0 (but not 192.168.0.50) and 127.0.0.1 will be allowed by the firewall.
In all other case handle() return false.
setDefaultState(false)defines default firewall response (Optional - Default false),addList($whiteList, 'local', true)defines$whiteListlist, calledlocalas allowed (true),addList($blackList, 'localBad', false);defines$blackListlist, calledlocalBadas rejected (false).
