(PECL)
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.
The service name.
The client remote address. Can be either an IP address or a domain name.
An optional user name.
If address looks like domain name then DNS is used to resolve it to IP address; set nodns to TRUE to avoid this.
This function returns TRUE if access should be granted, FALSE otherwise.
Ejemplo 1. Deny all connections from localhost
If your /etc/hosts.deny file contains:
php: 127.0.0.1
And your code looks like:
<?phpif (!tcpwrap_check('php', $_SERVER['REMOTE_ADDR'])) { die('You are not welcome here');}?>
For more details please consult hosts_access(3) man page.
