PHP MVC Toolbox

PHP Neoform

This is a toolbox I've developed over the years that has been used for many websites I've built. The primary mission I had when creating this library was to make the code fast and east to use. The main features of this toolbox:, _(*1)

• MVC and Bootstrapping:
  • Request\Request (immutable object composed of the HTTP request data)
  • Routed via a Router\Routes map (cached for performance)
  • Neoform\Router\Controller then generates a Render\View object (eg, HTML, JSON, or Raw)
  • Response\Response object is passed the rendered View
  • Bootstrap decides what to do with the Response, usually echoing it
• Service provider tools via Service\Service, allowing for resource based objects to only be activated when needed. This helps greatly when doing dependency injection whilst avoiding unnecessary resource allocation (eg, opening a MySQL or Redis connection).
• Session handling via Session\Auth that connects with a powerful ACL (Acl) that allows for user control via roles and groups.
• Entity mapping from a data source automatically gets cached at the record level. Multiple different types of cache can be employed. Unlike most entity caching systems, this one can use Memcache/Redis (or others) and will never serve stale cache.
  • Loading a Entity\Model is as easy as: Neoform\User\Model::fromPk(591);. If the record does not exist in cache, it will be fetched and saved to cache for every subsequent lookup.
  • Loading an Entity\Collection has the same feature set: Neoform\User\Collection::byStatus(2);. The result will be cached, and the cache will be deleted as soon as any Model in the Collection has changed.
• Configs that are object based located in an Config\Environment file, which is subsequently cached for performance. Instead of just dumping a bunch of random array values into a big messy config file, configs are validated twice before being compiled/cached. This means you can always trust the values found in the config file, even if it's been inherited multiple times.
  • Sad Face: echo isset($config['core']['site_name']) ? $config['core']['site_name'] : 'Oops';
  • Happy Face: echo Neoform\Core\Config::get()->getSiteName();.
• Input Validation is done via an extremely flexible Model/Collection design pattern that allows for Input\Validation objects to be created for various scenarios, and applied to the Input\Collection. If any value has an error, or is absent whilst listed as required, an Input\Error\Collection will be made available.
• Auto-Generation of Entity classes based on MySQL/PostgreSQL table mappings. Tables, Fields, Indexes and Foreign keys are used to map out the relationships between Entity objects. Subdivided into two main groups (Entity\Records and Entity\Links) you can interact with the Entities in a very natural way, and the code is all generated for you with a simple CLI script.

Composer Install

If you wish you can install PHP Neoform via Composer., _(*2)

Add neoform/neoform as a dependency in your project's composer.json file:, _(*3)

{
    "require": {
        "neoform/neoform": "dev-master"
    }
}

Examples

Sample Index:

<?php
    // Include the framework's core
    require_once(realpath(__DIR__ . "/../library/Neoform/Core.php"));

    $core = Neoform\Core::build(
        __DIR__ . '/..',
        'MyApp\Environment\\ProductionEnvironment'
    );

    // Create bootstrap for the MVC
    $bootstrap = new MyApp\Bootstrap(
        (isset($_SERVER['REQUEST_URI']) ? rawurldecode($_SERVER['REQUEST_URI']) : '/'),
        $_GET,
        $_POST,
        $_FILES,
        $_SERVER,
        $_COOKIE
    );

    $bootstrap
        ->buildResponse()
        ->render();

Sample Bootstrap:

                ->loadSession();
        }

        /**
         * Executes the bootstrap
         * When buffer output is turned off, all content and headers generated by views are sent straight to the browser
