ReactPHP Child Process Messenger/Pool Closure child class

Run closures in a child process messenger or pool

Installation

To install via Composer, use the command below, it will automatically detect the latest version and bind it with ~.

composer require wyrihaximus/react-child-process-closure 

Usage

Run a closure on the child process and get the results. (Note that results have to be a JSON serializable array.)

use React\EventLoop\Factory as EventLoopFactory;
use WyriHaximus\React\ChildProcess\Closure\ClosureChild;
use WyriHaximus\React\ChildProcess\Closure\MessageFactory;
use WyriHaximus\React\ChildProcess\Messenger\Factory as MessengerFactory;
use WyriHaximus\React\ChildProcess\Messenger\Messages\Payload;
use WyriHaximus\React\ChildProcess\Messenger\Messenger;

$loop = EventLoopFactory::create();

MessengerFactory::parentFromClass(ClosureChild::class, $loop)->then(function (Messenger $messenger) use ($loop) {
    $messenger->rpc(MessageFactory::rpc(function () {
        return resolve(['time' => time()]);
    })->done(function (Payload $payload) {
        echo 'Time in the child process: ', $payload['time'], PHP_EOL;
    });
});

$loop->run();

The usage example above also works with wyrihaximus/react-child-process-pool, just be sure to use WyriHaximus\React\ChildProcess\Closure\MessageFactory to create the RPC messages as shown in the example.
