Example #1 Creating Pools


<?php
class MyWorker extends Worker {
    
    public function __construct(Something $something) {
        $this->something = $something;
    }
    
    public function run() {

  ["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)
}
