Calling a CLI script inside a Phalcon MVC project

Hi,

I have a MVC application inside which I want to include a CLI project and call a task from a controller. Is this possible ? By the way, each element works fine except when I combine both.

Folder structure :

MyApp
    app
        config
        controllers
            MyController.php
        models
        tasks
            MyTask.php
        views
        cli.php

Controller :

        use Phalcon\Mvc\Model\Criteria;
        use Phalcon\Paginator\Adapter\Model as Paginator;

        class MyController extends ControllerBase {

            public function cliAction() {

                if (filter_input(INPUT_GET, 'ORDERID', FILTER_SANITIZE_ENCODED)) {

                    $orderID = filter_input(INPUT_GET, 'ORDERID', FILTER_SANITIZE_ENCODED);
                    $subscriberID = filter_input(INPUT_GET, 'SUBSCRIBERID', FILTER_SANITIZE_ENCODED);
                    $email = filter_input(INPUT_GET, 'CUSTOMEREMAIL', FILTER_SANITIZE_EMAIL);

                    if (filter_input(INPUT_GET, 'IP', FILTER_SANITIZE_ENCODED)) {

                        $IP = filter_input(INPUT_GET, 'IP', FILTER_SANITIZE_ENCODED);
                    } else {

                        $IP = filter_input(INPUT_SERVER, 'REMOTE_ADDR');
                    }

                    exec("php app/cli.php task main $orderID $subscriberID $email $IP");

                    $this->view->disable();
                }
            }
        }

Task :

    class mytaskTask extends \Phalcon\CLI\Task {

        public function mainAction(array $param) {

            $orderID = $param[0];
            $subscriberID = $param[1];
            $email = $param[2];
            $IP = $param[3];

            $timeZone = new DateTimeZone('America/Montreal');

            $date = new DateTime();
            $date->setTimezone($timeZone);
            $transactionDate = $date->format('Y-m-d h:i:s');

            $transactionLog = new TransactionLog();
            $transactionLog->IP = $IP;
            $transactionLog->Email = $email;
            $transactionLog->OrderID = $orderID;
            $transactionLog->SubscriberID = $subscriberID;
            $transactionLog->TransactionDate = $transactionDate;

            $transactionLog->create();
        }
    }

Thank you!
