Examples

Example #1 Submitting tasks to a specific worker

<?php
class Task extends Threaded {
    public function run() {
        var_dump(Thread::getCurrentThreadID());
    }
}

$pool = new Pool(2);

$pool->submit(new Task());

for ($i = 0; $i < 5; ++$i) {
    $pool->submitTo(0, new Task()); // stack all tasks onto the first worker
}

$pool->submitTo(1, new Task()); // cannot stack the task onto the second worker due to it not existing yet

$pool->shutdown();

The above example will output:

int(4475011072)
