Open Swoole 4.5.3 released

Swoole v4.5.3 is released with multiple new features and enhancement.

Swoole Process Manager

Swoole Process Manager can be used to manage multiple different functions and execute them within multiple processes.

Example:

<?php
$pm = new Swoole\Process\ProcessManager();
$atomic = new Atomic(0);
$pm->add(function (Pool $pool, int $workerId) use ($atomic) {
    usleep(100000);
    $atomic->wakeup();
});
$pm->add(function (Pool $pool, int $workerId) use ($atomic) {
    $atomic->wait(1.5);
    $pool->shutdown();
});
$pm->start();

Barrier

We can use Barrier to sync multiple coroutines since v4.5.3, wait until multiple coroutines are finished.

Example:

<?php
declare(strict_types=1);

use Swoole\Coroutine\Barrier;

Co\run(function() {
    $barrier = Barrier::make();
    $count = 0;
    $N = 4;
    foreach (range(1, $N) as $i) {
        \Swoole\Coroutine::create(function () use ($barrier, &$count) {
            System::sleep(5);
            $count++;
        });
    }
    Barrier::wait($barrier);
});

Coroutine::parallel

Coroutine::parallel can be used to run multiple copy of the function in multiple coroutines concurrently.

Example:

<?php
declare(strict_types=1);

use Swoole\Coroutine;
use Swoole\Runtime;
use function Swoole\Coroutine\parallel;

Co\run(function() {
    $c = 4;
    $results = [];
    parallel($c, function () use (&$results) {
        System::sleep(2);
        $results[] = System::gethostbyname('localhost');
    });
    var_dump($results);
});
