Pool::__construct — Creates a new Pool of Workers
説明
Construct a new pool of workers. Pools lazily create their threads, which means new threads will only be spawned when they are required to execute tasks.
パラメータ

The maximum number of workers for this pool to create
class-
The class for new Workers. If no class is given, then it defaults to the Worker class.
ctor-
An array of arguments to be passed to new workers' constructors
例

$this->something = $something;
}
public function run() {
/** ... **/
}
}
$pool = new Pool(8, \MyWorker::class, [new Something()]);
var_dump($pool);
?>上の例の出力は以下となります。
