/**
* 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.
*
