Composer also prepares an autoload file that's capable of autoloading all of the classes in any of the libraries that it downloads. To use it, just add the following line to your code's bootstrap process:
require 'vendor/autoload.php';
You can find out more on how to install Composer, configure autoloading, and other best-practices for defining dependencies at getcomposer.org.
Example event script
<?php
// include the composer autoloader
require_once __DIR__ . '/vendor/autoload.php';
use Mtdowling\Supervisor\EventListener;
use Mtdowling\Supervisor\EventNotification;
$listener = new EventListener();
$listener->listen(function(EventListener $listener, EventNotification $event) {
$listener->log($event->getEventName());
$listener->log($event->getServer());
$listener->log($event->getPool());
// Try messing around with supervisorctl to restart processes and see what
// data is available
$listener->log(var_export($event->getData(), true));
return true;
});
Running the example
Open your supervisord.conf file and add the following:
[eventlistener:event_listener]
command=php /path/to/examples/log.php
process_name=%(program_name)s_%(process_num)02d
numprocs=1
events=PROCESS_STATE_STARTING,TICK_5
