Description 

Author

This package can create threads and send messages between them.

It can create a parallel process and execute PHP code of a given callback function on that process.

It can also create mutexes that can be used to guarantee that only on process runs certain critical section code.

The processes may communicate sending and receiving messages between the master process and child processes. The communication may be implemented with different drives to use for instance message queues or Redis.

# Main Goal The mail goal of [Threadator](https://github.com/AlexanderC/Threadator) package is to provide an easy way to run multithreaded applications in PHP. You may notice that there are other packages like this, but: - This is a modern package (Using Generators, Traits and other language sugar + build as a composer library) - It is providing most native implementation ever (all that you need are posix, pcntl) - You have full controll on your threads (Mutex and bidirectional Communication betweed threads and master) # Installation - Via [Composer](https://getcomposer.org/) "alexanderc/threadator": "dev-master" # Basic usage ```php <?php require '/path/to/vendor/autoload.php'; $runtime = new \Threadator\Runtime(); $factory = new \Threadator\Factory($runtime); // instead of built in drivers names ["msgQueue", "redis"] you can use your own driver // by providing fully qualified class name (with NS), like My\CommunicationDriver\TestDriver // IMPORTANT: in order to get a stable work of communication- use "redis" instead of "msgQueue" $communication = \Threadator\Communication\Communication::create($runtime, 'msgQueue' /* 'redis', ['127.0.0.1'] */ ); $runtime->setCommunication($communication); // now we can create some threads for($i = 0; $i < 5; $i++) { // you can also use your own thread implementation by calling $factory->create("You\\Thread\\Implementation\\TestThread"); // IMPORTANT: your TestThread class should extend Threadator\Thread /** @var \Threadator\Thread $thread */ $thread = $factory->createCallable(function($thread) { // create mutex // for more mutex types check \Threadator\Mutex::T_* constants $mutex = $thread->createMutex("echo", \Threadator\Mutex::T_FUNCTION); // wait until we aquire the mutex $mutex->waitAcquire(); // do some work here... sleep(mt_rand(1, 3)); echo "Running Thread #{$thread->getPid()}...\n"; // wait until we get a message from the main process $thread->receiveMessage($message); // send back this message $thread->sendMessage("#{$thread->getPid()}: {$message}"); }); } echo "Main process #{$runtime->getPid()} running!\n"; // start all threads $runtime->run(); // send a message to all threads foreach($runtime->broadcastMessage(microtime(true)) as list($result, $thread)) { // if result == 1 than message was sent echo "Result for msg #{$thread->getPid()} -> {$result}\n"; } // wait until we receive thread messages $messages = []; foreach($runtime->receiveMessage() as $result => $message) { if($result) { $messages[] = $message; } } echo "Thread messages: " . implode(", ", $messages) . "\n"; // wait until all the threads runs $runtime->join(); exit("Main process #{$runtime->getPid()} stopped!\n"); ``` For more examples check "test" folder # Is it extendable Yes it is! You can easily write your communication driver or an thread implementation. # How to extend If you need to add (for example) a new communication driver- you just need to extend Threadator\Communication\Driver like this ```php <?php /** * @author AlexanderC <self@alexanderc.me> * @date 4/10/14 * @time 2:04 PM */ use Threadator\Communication\Driver\ADriver; class TestDriver extends ADriver { /** * @return void */ protected function init() { // TODO: Implement init() method. } /** * @param int $key * @param mixed $message * @return bool */ public function send($key, $message) { // TODO: Implement send() method. } /** * Try to get message, but do not block * * @param int $key * @param mixed $message * @return bool */ public function touch($key, & $message) { // TODO: Implement touch() method. } /** * Block until the first message arrives * * @param int $key * @param mixed $message * @return bool */ public function receive($key, & $message) { // TODO: Implement receive() method. } } ``` # ToDo - Create unit tests - Implement more communication drivers - ...your suggestions # Contributors - [AlexanderC](mailto:self@alexanderc.me) - ...[all contributors](https://github.com/AlexanderC/Threadator/graphs/contributors)
