(PECL pthreads >= 2.0.0)
Pool::__construct — Creates a new Pool of Workers
Description
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.
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
<?phpclass 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) }
