Hoa is a modular, extensible and structured set of PHP libraries. Moreover, Hoa aims at being a bridge between industrial and research worlds.

This library allows to transform a processus as a zombie: not alive, not dead!

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

To create a zombie, all we have to do is to call the Hoa\Zombie\Zombie::fork method. And 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!
Hoa\Zombie\Zombie::fork();
// I'm a zombie!
Hoa\Zombie\Zombie::decapitate();
// I'm dead…

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

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

echo 'I guess I am sick…', "\n";
Hoa\Zombie\Zombie::fork();

// Do whatever you want here, e.g.:
sleep(10);
file_put_contents(
    __DIR__ . DS . 'AMessage',
    'Hello from after-life… or somewhere about!'
);
Hoa\Zombie\Zombie::decapitate();

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

$fastcgi = new Hoa\Fastcgi\Responder(
    new Hoa\Socket\Client('tcp://127.0.0.1:9000')
);
echo $fastcgi->send(array(
    'GATEWAY_INTERFACE' => 'FastCGI/1.0',
    'REQUEST_METHOD'    => 'GET',
    'SCRIPT_FILENAME'   => __DIR__ . DS . 'Zombie.php'
));

And finally, we can test:

$ php-fpm -d listen=127.0.0.1:9000
$ 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!.
