Ding: Dependency Injection in your PHP Applications

About Ding

The name "Ding" comes from the action of using/doing dependency injection (DI), the result is something like "di'ing".

Also, Ding is based on (and tries to be designed as) the Spring framework from SpringSource, which offers a lot of great features not available to the php world. You now know where those great ideas came from ;) Ding also supports some of the JSR-250 and JSR-330 annotations, like @Configuration, @Bean, @Required, @Resource, etc.

Ding is intended to be used not only for web applications, but for desktop and embedded applications too. As a matter of fact, it has more features for desktop, server, and embedded applications than for web applications.

Where to find

You can find Ding:

Current Version

1.6.3 (If you are updating from 1.1.x please see README.1.3.x before upgrading to be sure about how it might affect you).

Features

  • Scalable architecture, allowing to easily adopt new features.
  • Supports XML, YAML, and annotations as bean definitions providers.
  • Lightweight, easy of use, and useful.
  • Loosed-couple, just use what you need and nothing more.
  • JSR-250: @PostConstruct, @PreDestroy, @Resouce
  • JSR-330: @Named, @Inject, @Singleton
  • Spring specific: @Configuration, @Primary, @Value, @Scope, @Component, @Aspect, @Required, @Bean, @Controller, @RequestMapping
  • Own specific: @Prototype, @InitMethod, @DestroyMethod, @ListensOn, @MethodInterceptor, @ExceptionInterceptor
  • Aware interfaces: IContainerAware, IMessageSourceAware, IResourceLoaderAware, IBeanNameAware, IAspectManagerAware, ILoggerAware
  • Bean inheritance through normal OOP or xml/yaml declarations.
  • Bean aliasing for xml, yaml, and annotations.
  • Extensions in the lifecycle: AfterDefinition, BeforeCreate, AfterCreate, BeforeAssemble, AfterAssemble
  • Extensions for providing your own definitions: IBeanDefinitionProvider, IAspectProvider, IPointcutProvider
  • Resources through php streams.
  • Setter Injection (For arrays, scalar values, php code, and references to other beans).
  • Constructor Injection (For the same data types as above).
  • Method Injection (So you can have dependencies in singletons that must be created on demand).
  • Can define factory beans, factory classes, and factory methods to create beans.
  • Managed bean lifecycle (for singletons and prototypes).
  • Initialization and destruction methods called by the container.
  • Aspects (as in aspect oriented programming), for xml, yaml, and annotation drivers.
  • Lightweight implementation of the MVC (Model View Controller) pattern. Can be used with or without Twig, and Smarty
  • Annotations used by helpers and the container (i.e: @InitMethod, @DestroyMethod, @Controller, etc).
  • Can cache proxies and bean definitions with Zend_Cache, Memcached, Filesystem, and APC.
  • Integration with PAMI and PAGI. So you can make asterisk (telephony) applications via agi and ami.
  • Helpers: Syslog, TCPServer, TCPClient, etc.
  • Error Handling, Signal Handling, Shutdown Handling, all via events.

See the README file for more information.
