Beispiel #1 Creating Pools


<?php
class MyWork extends Stackable {
    public function __construct() {
        $this->complete = false;
    }

    public function run() {
        printf(
            "Hello from %s in Thread #%lu\n", 
            __CLASS__, $this->worker->getThreadId());
        $this->complete = true;
    }

    public function isComplete() { 
        return $this->complete; 
    }

    protected $complete;
}

class MyWorker extends Worker {
    
    public function __construct(Something $something) {
        $this->something = $something;
    }
    
    public function run() {
        /** ... **/
    }
}

$pool = new Pool(8, \MyWorker::class, [new Something()]);
$pool->submit(new MyWork());

usleep(1000);

$pool->collect(function($work){
    return $work->isComplete();
});
var_dump($pool);
?>

Das oben gezeigte Beispiel erzeugt folgende Ausgabe:
