/**
 * PHP_Fork class usage examples
 * ==================================================================================
 * NOTE: In real world you surely want to keep each class into
 * a separate file, then include() it into your application.
 * For this examples is more useful to keep all_code_into_one_file,
 * so that each example shows a unique feature of the PHP_Fork framework.
 * ==================================================================================
 * basic.php
 *
 * This is the most basic example I can think about...
 * Simply increment an internal counter every second, printing it to
 * stdout. Repeat this 10 times, then exit. The class extends PHP_Fork, so we have
 * multiple instances running cuncurrently, as shown by the timestamp of each thread.
 *
