Example:

$Threads = [];
$Threads[] = new Thread(function(Thread $Thread) {
	$Thread->saveData(file_get_contents($Thread->getLaunchParams()[0]));
});
$Threads[] = clone $Threads[0];
$Threads[] = clone $Threads[0];
 
$Threads[0]->run('http://ya.ru');
$Threads[1]->run('http://mail.ru');
$Threads[2]->run('http://r0.ru');

while (array_filter($Threads, function (Thread $Thread) {return $Thread->isChildAlive();})) {
	sleep(1);
}

array_walk($Threads, function(Thread $Thread) {
	var_dump($Thread->getSavedResult());
});

ThreadPool

• Allows to execute unlimited number of threads.
• Manages child tasks and respawns them if they died without setting their status as "complete".
• It is useful to execute scripts with memory leak.
• Can be used for daemon implementation. Example:

$res = (new ThreadPool(10)) //threads count
	->setTask(function (Thread $Thread) {
		$data = $Thread->getSavedData();
		$i = isset($data['i']) ? $data['i'] : 0;
		$i++;
		var_dump($i);

		$Thread->saveResult([
			'i'   => $i,
			'num' => $Thread->getThreadNumber(),
		]);

		if ($i >= 10) {//script will exit after 10 iterations/launches
			$Thread->markFinished();
		}
	})->setInterruptedHandler(function (Thread $Thread, $signo) {
		//dump current state before exit
		file_put_contents('worker_' . $Thread->getThreadNumber(), json_encode($Thread->getSavedResult()));
		trigger_error('Interrupted with signal ' . $signo);
	})->run();

var_dump($res);

// will return [
//     0 => [
//         'i'   => 10,
//         'num' => 0
//     ],
//     1 => [
//         'i'   => 10,
//         'num' => 1
//     ]
// ];
