This library allows to transform a process into a zombie: not alive, nor dead!

This is possible only if the program is running behind PHP-FPM (which manages processes for us).

Learn more.


With Composer, to include this library into your dependencies, you need to require hoa/zombie:

$ composer require hoa/zombie '~3.0'

For more installation procedures, please read the Source page.


Before running the test suites, the development dependencies must be installed:

$ composer install

Then, to run all the test suites:

$ vendor/bin/hoa test:run

For more information, please read the contributor guide.

Quick usage

To create a zombie, all we have to do is to call the Hoa\Zombie\Zombie::fork method. To kill a zombie, we have the choice between different weapons:

  • Hoa\Zombie\Zombie::decapitate, ziip;
  • Hoa\Zombie\Zombie::bludgeon, tap tap;
  • Hoa\Zombie\Zombie::burn, if you are cold;
  • Hoa\Zombie\Zombie::explode, boom;
  • Hoa\Zombie\Zombie::cutOff, sausage?

All these methods have been proven. Thus:

// I'm alive!
// I'm a zombie!
// I'm dead…

But we have to run the script behind FastCGI, that is why we will use the Hoa\Fastcgi library in the following example.

In the Zombie.php file, we write the following instructions:

echo 'I guess I am sick…', "\n";

// Do whatever you want here, e.g.:
    __DIR__ . DS . 'AMessage',
    'Hello from after-life… or somewhere about!'

Then, in the Run.php file, we write:

$fastcgi = new Hoa\Fastcgi\Responder(
    new Hoa\Socket\Client('tcp://')
echo $fastcgi->send([
    'GATEWAY_INTERFACE' => 'FastCGI/1.0',
    'REQUEST_METHOD'    => 'GET',
    'SCRIPT_FILENAME'   => __DIR__ . DS . 'Zombie.php'

And finally, we can test:

$ php-fpm -d listen=
$ php Run.php
I guess I am sick…

And 10 seconds after, we will see the AMessage file appear with the content: Hello from after-life… or somewhere about!.


The hack book of Hoa\Zombie contains detailed information about how to use this library and how it works.

To generate the documentation locally, execute the following commands:

$ composer require --dev hoa/devtools
$ vendor/bin/hoa devtools:documentation --open
