README

A lightweight concurrency framework for PHP based on zeromq.

Summary

Brook was created to make concurrent stream processing more accessible in PHP. It's built on top of zeromq and uses the fan-out pattern to distribute work.

Usage

Here is a simple examlpe where 20 messages are fanned out and multiplied then collected and confirmed back in the main thread of execution.

 class MultiplicationTask implements \Brook\TaskInterface {
   const MULTIPLIER = 2;

   public function setup() { }
   public function tearDown() { }

   public function work($value) {
     return sprintf("%d %d", $value, $value * self::MULTIPLIER);
   }
 }


 $messageCount = 20;

 $fanOut = new Brook\FanOut();
 $fanOut->distributeWork(2, new MultiplicationTask());

 for ($i=1; $i<=$messageCount; $i++) {
   $fanOut->enqueue($i);
   echo "sent $i", PHP_EOL;
 }

 for ($i=1; $i<=$messageCount; $i++) {
   $result = $fanOut->readFromSink();
   list($value, $multiplied) = explode(' ', $result);

   echo "got $value, $multiplied", PHP_EOL;
   assert($multiplied == (MultiplicationTask::MULTIPLIER * $value));
 }

 $fanOut->shutdown();
