PHP-Handbuch: Creates a new Pool of Workers

Beschreibung

public Pool Pool::__construct ( integer $size [, string $class [, array $ctor ]] )

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.

Parameter-Liste

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: An array of arguments to be passed to new workers' constructors

Rückgabewerte

The new pool

Beispiele

Beispiel #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);
?>

Das oben gezeigte Beispiel erzeugt folgende Ausgabe:

object(Pool)#1 (6) {
  ["size":protected]=>
  int(8)
  ["class":protected]=>
  string(8) "MyWorker"
  ["workers":protected]=>
  NULL
  ["work":protected]=>
  NULL
  ["ctor":protected]=>
  array(1) {
    [0]=>
    object(Something)#2 (0) {
    }
  }
  ["last":protected]=>
  int(0)
}
