This package can process events with collections of objects.

There is a container class that can hold a collection of objects treating it like an array.

The container class can invoke custom functions to all objects in the collection, sort the objects, dispatch events using an object handler class, and perform all other operations typical of arrays.

<?php
include 'objbox.class.php';
include 'objhandler.class.php';
// small debug helper function
function debug($var) { echo "<pre>".stripslashes(var_export($var,true))."</pre>"; }

// an example event handler function
function event_handler( event $ev ) {
  debug($ev);
}

// set the evenet handler
objhandler::set_event_handler('event_handler');

// an example object to be passed around
class passobj {
  public $var = 0;
}

// an axample object number 1
class example1 {

  public function hook($obj) {
    debug("example1");
    $obj->var++;

  }
  public function hook_with_exception() {
    throw new exception('some bad has happened.');
  }

}

// an example object number 2
class example2 {

  public function hook($obj) {
    echo debug("example2");
    $obj->var++;
  }
  public function hook_with_exception() {
    // nothing bad happened here
    //throw new exception('some bad has happened.');
  }
}

// create the new container
$box = new objbox();

// add some objects
$box['e1'] = new example1();
$box[] = new example2();
debug($box);

$var = new passobj();
debug($var);

$box->hook($var); // var plus 2 | 2 Events are fired

debug($var);

// access directly like this
$box['e1']->hook($var); // var plus 1 | Event is fired
// or like this
$box->e1->hook($var); // var plus 1 | Event is fired

debug($var);

$box->hook_with_exception(); // 3 events are fired, to calls, and 1 exception
