A small simple multi-threading library to include in projects

Recent Update

The project just got released on packagist with release 1.0.0.


You need to have composer and autloader installed. To be able to install the package, add this entry in the "repositories" index of your composer.json

        "type": "vcs",
        "url":  ""

Just require the package with composer

composer require alicemajere/wonderland-thread


To start a multi-threading Pool, just create a new instance of ThreadPool

$threadPool = new ThreadPool(); 

We setup a maximum number of Thread to run at the same time. If we add 200 Threads to the Pool, only 5 of them will run at the same time until the Pool processed all the 200 Threads


Add one or more Thread to the Pool by creating a new instance of Thread. A Thread take two parameters, a name and a closure function that will tell the Thread what to do. The closure have to return an exit status from the ones defined in the Thread class constants.

$thread = ThreadFactory::create(
    function ($processName) {
        // Implements the Thread processing here
        echo $processName . PHP_EOL;
        // return an exit status at the end of the thread
        return Thread::EXIT_STATUS_SUCCESS;


To run the ThreadPool, you can just do


You can add Listeners that will trigger on a particular Event while the Pool is running the Threads. Using Listeners can be useful if you need to do particular things for every Threads, like opening a separate mysql connection for every Thread. A Listener object constructor need the Event name to listen to and a closure function that will tell the Listener what to do for this Event. The full list of Event definition is found in the Event class.

$threadPool->addListener(new Listener(
    Event::POOL_RUN_START, // Event to trigger the listener
    function (Event $event) use ($website) {
        // Implements the listener
$threadPool->addListener(new Listener(
    function (Event $event) {
