Pool::__construct — Creates a new Pool of Workers
public Pool::__construct ( int $size [, string $class [, array $ctor ]] ) : Pool
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.
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
The new pool
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) }
