tcpwrap_check - Performs a tcpwrap check

SYNOPSIS
       bool tcpwrap_check (string  $daemon, string  $address, [string  $user], [bool  $nodns = false])

DESCRIPTION
	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
	      o $daemon
		- The service name.

	      o $address
		- The client remote address. Can be either an IP address or a domain name.

	      o $user
		- An optional user name.

	      o $nodns
		- If $address looks like domain name then DNS is used to resolve it to IP address; set $nodns to TRUE to avoid this.

RETURN VALUES
	This function returns TRUE if access should be granted, FALSE otherwise.

EXAMPLES
       Example #1

	      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');
	      }
	      ?>
