Pool::__construct

(PECL pthreads >= 2.0.0)

Pool::__constructCreates a new Pool of Workers

Description

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.

Parameters

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

Return Values

The new pool

Examples

Example #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);
?>

The above example will output:

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)
}
