Features of FuelPHP

Using a Bespoke PHP or a custom-developed framework could give you a greater performance. FuelPHP provides many features, documentation, and a great community. The following sections describe some of the most useful features.

(H)MVC Although FuelPHP is a Model-View-Controller (MVC) framework, it was built to support the HMVC variant of MVC. Chapter 3, The Architecture, covers the MVC design pattern in detail. Hierarchical Model-View-Controller (HMVC) is a way of separating logic and then reusing the controller logic in multiple places. This means that when a web page is generated using a theme or a template section, it can be split into multiple sections or widgets. Using this approach, it is possible to reuse components or functionality throughout a project or in multiple projects. In addition to the usual MVC structure, FuelPHP allows the use of presentation modules (ViewModels). These are a powerful layer that sits between the controller and the views, allowing for a smaller controller while still separating the view logic from both the controller and the views. If this isn't enough, FuelPHP also supports a router-based approach where you can directly route to a closure. This then deals with the execution of the input URI.

Modular and extendable The core of FuelPHP has been designed so that it can be extended without the need for changing any code in the core. It introduces the notion of packages, which are self-contained functionality that can be shared between projects and people. Like the core, in the new versions of FuelPHP, these can be installed via the Composer tool. Just like packages, functionality can also be divided into modules. For example, a full user-authentication module can be created to handle user actions, such as registration. Modules can include both logic and views, and they can be shared between projects. The main difference between packages and modules is that packages can be extensions of the core functionality and they are not routable, while modules are routable. Both packages and modules are covered in Chapter 5, Packages and Chapter 6, Advanced Topics.

Security Everyone wants their applications to be as secure as possible; to this end, FuelPHP handles some of the basics for you. Views in FuelPHP will encode all the output to ensure that it's secure and is capable of avoiding Cross-site scripting (XSS) attacks. This behavior can be overridden or can be cleaned by the included htmLawed library. The framework also supports Cross-site request forgery (CSRF) prevention with tokens, input filtering, and the query builder, which tries to help in preventing SQL injection attacks. PHPSecLib is used to offer some of the security features in the framework.

Oil â the power of the command line If you are familiar with CakePHP or the Zend framework or Ruby on Rails, then you will be comfortable with FuelPHP Oil. It is the command-line utility at the heart of FuelPHPâdesigned to speed up development and efficiency. It also helps with testing and debugging. Although not essential, it proves indispensable during development. Oil provides a quick way for code generation, scaffolding, running database migrations, debugging, and cron-like tasks for background operations. It can also be used for custom tasks and background processes. Oil is a package and can be found at https://github.com/fuel/oil.

ORM FuelPHP also comes with an Object Relation Mapper (ORM) package that helps in working with various databases through an object-oriented approach. It is relatively lightweight and is not supposed to replace the more complex ORMs such as Doctrine or Propel. The ORM also supports data relations such as: belongs-to

has-one

has-many

many-to-many relationships Another nice feature is cascading deletions; in this case, the ORM will delete all the data associated with a single entry. The ORM package is available separately from FuelPHP and is hosted on GitHub at https://github.com/fuel/orm.

Base controller classes and model classes FuelPHP includes several classes to give a head start on projects. These include controllers that help with templates, one for constructing RESTful APIs, and another that combines both templates and RESTful APIs. On the model side, base classes include CRUD (Create, Read, Update, and Delete) operations. There is a model for soft deletion of records, one for nested sets, and lastly a temporal model. This is an easy way of keeping revisions of data.

The authentication package The authentication framework gives a good basis for user authentication and login functionality. It can be extended using drivers for new authentication methods. Some of the basics such as groups, basic ACL functions, and password hashing can be handled directly in the authentication framework. Although the authentication package is included when installing FuelPHP, it can be upgraded separately to the rest of the application. The code can be obtained from https://github.com/fuel/auth.

Template parsers The parser package makes it even easier to separate logic from views instead of embedding basic PHP into the views. FuelPHP supports many template languages, such as Twig, Markdown, Smarty, and HTML Abstraction Markup Language (Haml).
