README

ConcurrencyHelper is a library for easily and efficiently running any callable via multiple parallel PHP instances.

It's aim is to substantially simplify massively parallelized operations.

Notable use cases include the Bettergist Collector project, which uses ConcurrencyHelper to massively parallize the downloads of every www.Packagist.org package, using 50-200 PHP processes.

This library requires the ext-pcntl extension.

Usage

```php
$myParallelizedFunction = function (int $childNumber, array $packages, $optionalExtraParameter) {
echo "Thread $childNumber: " . implode(', ', $packages) . " of $optionalExtraParameter\n";

    sleep($childNumber * 1);

    echo "Finished Thread $childNumber.\n";
};

$states = [
'Alabama', 'Alaska', 'Arizona', 'Arkansas', 'California', 'Colorado',
'Connecticut', 'Delaware', 'Florida', 'Georgia', 'Hawaii', 'Idaho',
];

$runner = new BettergistCollective\ConcurrencyHelper\ConcurrencyHelper();
$runner->concurrentlyRun($states, 6, $myParallelizedFunction, [count($states)]);
```
