Tiny library that simplifies launching multiple processes in parallel (or not).

Installation

composer require norberttech/symfony-process-executor

Examples

<?php

use NorbertTech\SymfonyProcessExecutor\AsynchronousExecutor;
use NorbertTech\SymfonyProcessExecutor\ProcessPool;
use NorbertTech\SymfonyProcessExecutor\ProcessWrapper;
use Symfony\Component\Process\Process;
use Aeon\Calendar\TimeUnit;

$processes = new ProcessPool(
    Process::fromShellCommandline('sleep 1 && echo 1'),
    Process::fromShellCommandline('sleep 2 && echo 2'),
    Process::fromShellCommandline('sleep 3 && echo 3'),
    Process::fromShellCommandline('sleep 4 && echo 4'),
    Process::fromShellCommandline('sleep 5 && echo 5')
);

$executor = new AsynchronousExecutor(
    pool: $processes,
    sleep: TimeUnit::milliseconds(100), // delay between checking for process completion
    timeout: TimeUnit::seconds(12),  // total timeout for all processes
    batchSize: 2 // number of processes to run in parallel at once, when null all processes will be run in parallel
);

$executor->execute();

$executor->pool()->each(function (ProcessWrapper $processWrapper) {
    var_dump($processWrapper->exitCode());
    var_dump(\trim($processWrapper->output()));
    var_dump($processWrapper->executionTime()->inSeconds());
    var_dump($processWrapper->executionTime()->inMilliseconds());
    var_dump($processWrapper->executionTime()->microsecond());
    echo "----\n";
});

echo \sprintf("Successfully finished child processes: %d\n", $executor->pool()->withSuccessExitCode());
echo \sprintf("Failure finished child processes: %d\n", $executor->pool()->withFailureExitCode());
echo \sprintf("Total execution time [s]: %d\n", $executor->executionTime()->inSecondsPreciseString());
