Using Eloquent Model without the whole Laravel structure

EloquentModel.php

<?php

class EloquentModel extends Illuminate\Database\Eloquent\Model {
    public function getConnection()
    {
        // In case of Phalcon 3.4
        $di = new \Phalcon\Di();
        $config = $di->getDefault()->getShared('config');
        $db = $config['database'];
        $host = explode(':', $db->host);
        $host = 'mysql:host='.$host[0].';port='.$host[1].';dbname='.$db->dbname;
        $username = $db->username;
        $password = $db->password;

        // If you are using structured PHP or another project, just remember to use this syntax:
        // $host = 'mysql:host=172.17.0.1;port=3306;dbname=mydatabase';
        return new Illuminate\Database\MySqlConnection(
            new PDO($host, $username, $password)
        );
    }
}

/*
 * Then create a class extending `EloquentModel`, remember to use the Classname
 * as the singular of the table name, otherwise you will have to set it manually
