/**
 * ---------------------------------------------------------------------------------------------------------------------
 * DESCRIPTION
 * ---------------------------------------------------------------------------------------------------------------------
 * This file contains the example of using methods created for getting the information about the incoming/outcoming
 * socket connections.
 *
 * ---------------------------------------------------------------------------------------------------------------------
 * USAGE
 * ---------------------------------------------------------------------------------------------------------------------
 * To run this example in CLI from project root use following syntax
 *
 * $> php ./example/socket_info.php
 *
 * Following flags are supported to test example:
 *
 * --mode  : define whether socket or client should be created, default: standard, supported: [ client, server ]
 *
 * Remember that to see working communication, you need to create server and at least one client!
 *
 * $> php ./example/socket_info.php --mode=server
 * $> php ./example/socket_info.php --mode=client
 *
