Class Phalcon\Mvc\Model\MetaData\Session

extends abstract class Phalcon\Mvc\Model\MetaData

implements Phalcon\Mvc\Model\MetaDataInterface, Phalcon\Di\InjectionAwareInterface

Source on GitHub

Stores model meta-data in session. Data will erased when the session finishes. Meta-data are permanent while the session is active.

You can query the meta-data by printing $_SESSION[‘$PMM$’]

<?php

$metaData = new \Phalcon\Mvc\Model\Metadata\Session(
    [
       "prefix" => "my-app-id",
    ]
);
