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
-
size -
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 -

例
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]=>
NULL
["work":protected]=>
NULL
["ctor":protected]=>
