README

ext-parallel runtime wrapping adding error, signal, and exception handling.

Installation

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

composer require wyrihaximus/parallel-runtime

Usage

The Runtime class transparently wraps ext-parallel's runtime class. But instead of what you return from your closure it will return an Outcome object. The Outcome object containers the results of your closure, but also any reported errors. Consider the following example:

<?php

declare(strict_types=1);

use WyriHaximus\Parallel\Runtime;

use function trigger_error;

use const WyriHaximus\Constants\ComposerAutoloader\LOCATION;

$runtime = new Runtime(LOCATION);
$future  = $runtime->run(static function (): string {
    trigger_error('Error! Error! Error!');

    return 'yay';
});
posix_kill(posix_getpid(), SIGUSR1);
$outcome = $future->value();
echo get_class($outcome), PHP_EOL; // WyriHaximus\Parallel\Outcome
echo $outcome->result(), PHP_EOL; // yay
foreach ($outcome->errors() as $error) {
    echo $error->message(), PHP_EOL; // Error! Error! Error!
}
foreach ($outcome->signals() as $signal) {
    echo $signal->signal(), PHP_EOL; // SIGUSR1
}
