Listeners

Listeners are object that are used when an event is fired!

<?php
namespace My\NM;

class Error
{
    public function error()
    {

    }
}

Of course we have to link listeners through the configuration:

// configs/app.php

"services" => arrray(
    "invokables" => array(
        "My\\NM\\Error" => "My\\NM\\Error",
    )
),
"listeners" => array(
    "404" => array(
        array("My\\NM\\Error", "error")
    )
)
