(PECL tcpwrap >= 0.1.0)
Performs a tcpwrap check
bool tcpwrap_check ( string $daemon, string $address [, string $user [, bool $nodns = false ]] )
This function consults the /etc/hosts.allow and /etc/hosts.deny files to check if access to service daemon should be granted or denied for a client.
Parameters:
daemon
The service name.
address
The client remote address. Can be either an IP address or a domain name.
user
An optional user name.
nodns
If address looks like domain name then DNS is used to resolve it to IP address; set nodns to TRUE to avoid this.
Returns:
This function returns TRUE if access should be granted, FALSE otherwise.
Examples:
Deny all connections from localhost
If your /etc/hosts.deny file contains:
php: 127.0.0.1
And your code looks like:
<?php
if (!tcpwrap_check('php', $_SERVER['REMOTE_ADDR'])) {
die('You are not welcome here');
}
?>
