Class Phalcon\Config

implements ArrayAccess, Countable

Source on GitHub

Phalcon\Config is designed to simplify the access to, and the use of, configuration data within applications. It provides a nested object property based user interface for accessing this configuration data within application code.

<?php
$config = new \Phalcon\Config(
    [
        "database" => [
            "adapter"  => "Mysql",
            "host"     => "localhost",
            "username" => "scott",
            "password" => "cheetah",
            "dbname"   => "test_db",
        ],
        "phalcon" => [
            "controllersDir" => "../app/controllers/",
            "modelsDir"      => "../app/models/",
            "viewsDir"       => "../app/views/",
        ],
    ]
);
