Example script that uses pcntl_fork() to fork itself a few dozen times, and System V IPC functions to create a message queue,
  let the child processes send data to it and the parent process read and display it.

#!/usr/bin/env php
<?php
// Create or attach to a message queue
$queue = msg_get_queue(ftok(__FILE__, 'a'), 0600); # set permissions so that only the owner can read/write to this queue
# ftok() creates a message queue key based on the file's inode and a single character project identifier. The latter lets
# one create several queues all based on/in the same file.
