Pool::__construct — Creates a new Pool of Workers
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.
sizeThe maximum number of workers for this pool to create
classThe class for new Workers. If no class is given, then it defaults to the Worker class.
ctorAn array of arguments to be passed to new workers' constructors
例1 Creating Pools
<?php
class MyWorker extends Worker {
public function __construct(Something $something) {
$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。
object(Pool)#1 (6) {
["size":protected]=>
int(8)
["class":protected]=>
string(8) "MyWorker"
["workers":protected]=>

["work":protected]=>
