You may integrate your application queue (such as Redis) with Queue Worker Controller. PHP is a lack of support for multithreading at the core language level, this library implements multithreading by managing multiprocessing. For more concepts, the following diagram shows the implementation structure of this library: [![](https://raw.githubusercontent.com/yidas/codeigniter-queue-worker/master/img/introduction-structure.png)](https://raw.githubusercontent.com/yidas/codeigniter-queue-worker/master/img/introduction-structure.png) Listener (Daemon) could continue to run for detecting new jobs until it is manually stopped or you close your terminal. On the other hand , Worker could continue to run for processing new jobs until there is no job left, which the workers could be called by Listener. Launcher is suitable for launching a listener process, which the running Listener process could be unique that the second launch would detect existent listener and do NOT launch again. --- REQUIREMENTS ------------ [](#requirements) This library requires the following: - PHP CLI 5.4.0+ - CodeIgniter 3.0.0+ --- INSTALLATION ------------ [](#installation) Run Composer in your Codeigniter project under the folder `\application`: ``` composer require yidas/codeigniter-queue-worker ``` Check Codeigniter `application/config/config.php`: ``` $config['composer_autoload'] = TRUE; ``` > You could customize the vendor path into `$config['composer_autoload']` --- CONFIGURATION ------------- [](#configuration) First, create a controller that extends the working controller, and then use your own queue driver to design your own handler to implement the worker controller. There are common interfaces as following: ``` use yidas\queue\worker\Controller as WorkerController; class My_worker extends WorkerController { // Initializer protected function init() {} // Worker protected function handleWork() {} // Listener protected function handleListen() {} } ``` These handlers are supposed to be designed for detecting the same job queue, but for different purpose. For example, if you are using Redis as message queue, Listener and Worker detect the same Redis list queue, Listener only do dispatching jobs by forking Worker, while Worker continue to takes out jobs and do the processing until job queue is empty. ### How to Design a Worker [](#how-to-design-a-worker) #### 1. Build Initializer [](#1-build-initializer) ``` protected void init() ``` The `init()` method is the constructor of worker controller, it provides you with an interface for defining initializartion such as Codeigniter library loading. *Example Code:* ``` class My_worker extends \yidas\queue\worker\Controller { protected function init() { // Optional autoload (Load your own libraries or models) $this->load->library('myjobs'); } // ... ``` > As above, `myjobs` library is defined by your own application which handles your job processes. [Example code of myjobs with Redis](https://github.com/yidas/codeigniter-queue-worker/blob/master/examples/myjobs/MyjobsWithRedis.php) #### 2. Build Worker [](#2-build-worker) ``` protected boolean handleWork(object $static=null) ``` The `handleWork()` method is a processor for Worker that continue to take out jobs and do the processing. When this method returns `false`, that means the job queue is empty and the worker will close itself. *Example Code:* ``` class My_worker extends \yidas\queue\worker\Controller { protected function handleWork() { // Your own method to get a job from your queue in the application $job = $this->myjobs->popJob(); // return `false` for job not found, which would close the worker itself. if (!$job) return false; // Your own method to process a job $this->myjobs->processJob($job); // return `true` for job existing, which would keep handling. return true; } // ... ``` #### 3. Build Listener [](#3-build-listener) ``` protected boolean handleListen(object $static=null) ``` The `handleListen()` method is a processor for Listener that dispatches workers to handle jobs while it detects new job by returning `true`. When this method returns `false`, that means the job queue is empty and the listener will stop dispatching. *Example Code:* ``` class My_worker extends \yidas\queue\worker\Controller { protected function handleListen() { // Your own method to detect job existence // return `true` for job existing, which leads to dispatch worker(s). // return `false` for job not found, which would keep detecting new job return $this->myjobs->exists(); } // ... ``` ### Porperties Setting [](#porperties-setting) You could customize your worker by defining properties. ``` use yidas\queue\worker\Controller as WorkerController; class My_worker extends WorkerController { // Setting for that a listener could fork up to 10 workers public $workerMaxNum = 10; // Enable text log writen into specified file for listener and worker public $logPath = 'tmp/my-worker.log'; } ``` #### Public Properties [](#public-properties) PropertyTypeDeafultDescription$debugbooleantrueDebug mode$logPathstringnullLog file path$phpCommandstring'php'PHP CLI command for current environment$listenerSleepinteger3Time interval of listen frequency on idle$workerSleepinteger0Time interval of worker processes frequency$workerMaxNuminteger4Number of max workers$workerStartNuminteger1Number of workers at start, less than or equal to $workerMaxNum$workerWaitSecondsinteger10Waiting time between worker started and next worker starting$workerHeathCheckbooleantrueEnable worker health check for listener--- USAGE ----- [](#usage) There are 3 actions for usage: - `listen` A listener (Daemon) to manage and dispatch jobs by forking workers. - `work` A worker to process and solve jobs from queue. - `launch` A launcher to run `listen` or `work` process in background and keep it running uniquely. You could run above actions by using Codeigniter 3 PHP-CLI command after configuring a Queue Worker controller. ### Running Queue Worker [](#running-queue-worker) #### Worker [](#worker) To process new jobs from the queue, you could simply run Worker: ``` $ php index.php myjob/work ``` As your worker processor `handleWork()`, the worker will continue to run (return `true`) until the job queue is empty (return `false`). #### Listener [](#listener) To start a listener to manage workers, you could simply run Listener: ``` $ php index.php myjob/listen ``` As your listener processor `handleListen()`, the listener will dispatch workers when detecting new jobs (return `true`) until the job queue is empty with stopping dispatching and listening for next new jobs (return `false`). Listener manage Workers by forking each Worker into running process, it implements Multi-Processes which could dramatically improve job queue performance. ### Running in Background [](#running-in-background) This library supports running Listener or Worker permanently in the background, it provides you the ability to run Worker as service. #### Launcher [](#launcher) To run Listener or Worker in the background, you could call Launcher to launch process: ``` $ php index.php myjob/launch ``` By default, Launcher would launch `listen` process, you could also launch `work` by giving parameter: ``` $ php index.php myjob/launch/worker ``` Launcher could keep launching process running uniquely, which prevents multiple same listeners or workers running at the same time. For example, the first time to launch a listener: ``` $ php index.php myjob/launch Success to launch process `listen`: myjob/listen. Called command: php /srv/ci-project/index.php myjob/listen > /dev/null & ------ USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND user 14650 0.0 0.7 327144 29836 pts/3 R+ 15:43 0:00 php /srv/ci-project/index.php myjob/listen ``` Then, when you launch the listener again, Launcher would prevent repeated running: ``` $ php index.php myjob/launch Skip: Same process `listen` is running: myjob/listen. ------ USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND user 14650 0.4 0.9 337764 36616 pts/3 S 15:43 0:00 php /srv/ci-project/index.php myjob/listen ``` For uniquely work scenario, you may use database as application queue, which would lead to race condition if there are multiple workers handling the same jobs. Unlike memcache list, database queue should be processed by only one worker at the same time. #### Process Status [](#process-status) After launching a listener, you could check the listener service by command `ps aux|grep php`: ``` ... www-data 2278 0.7 1.0 496852 84144 ? S Sep25 37:29 php-fpm: pool www www-data 3129 0.0 0.4 327252 31064 ? S Sep10 0:34 php /srv/ci-project/index.php myjob/listen ... ``` According to above, you could manage listener and workers such as killing listener by command `kill 3129`. Workers would run while listener detected job, the running worker processes would also show in `ps aux|grep php`. > Manually, you could also use an `&` (an ampersand) at the end of the listener or worker to run in the background. ### Health Score 21 — LowBetter than 18% of packages Maintenance20 Infrequent updates — may be unmaintained Popularity5 Limited adoption so far Community6 Small or concentrated contributor base Maturity44 Maturing project, gaining track record Bus Factor1 Top contributor holds 100% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
