1. ZF2 For COMMON by Ralph Schindler Wednesday, April 10, 13
2. Who Am I? •Ralph Schindler (ralphschindler) Software Engineer on the Zend Framework team •At Zend for 5 years •Before that TippingPoint/3Com Programming PHP for 13+ years Live in New Orleans, LA. •Lived in Austin, Tx for 5 years 2 Wednesday, April 10, 13
3. Before we get started •Slides: https://speakerdeck.com/ralphschindler/zf2-for-common 3 Wednesday, April 10, 13
4. Outline of Talk •ZF2 Intro •ZF2 Application Quickstart •MVC Application Core Concepts •Zend\Db Connectivity •Modules / Exploring / Development 4 Wednesday, April 10, 13
5. ZF 2.0 •Next generation of Zend Framework •Embrace 5.3 (and 5.4 in some places, not required) •Embrace multiple programming paradigms AOP Event driven programming •More SOLID http://en.wikipedia.org/wiki/SOLID_(object-oriented_design) More interfaces, more possibility for extension Practice dependency injection •More Agile and open! No more CLA Code on github.com 5 Wednesday, April 10, 13
6. Insert->Header & Footer ZF2 Application Quickstart 6 Wednesday, April 10, 13
7. Quickstart •Get ZF2 Application Skeleton: download the zip [or] use composer’s create-skeleton 7 Wednesday, April 10, 13
8. Skeleton •Download skeleton https://github.com/zendframework/ZendSkeletonApplication •Copy files to project on i •Start coding! 8 Wednesday, April 10, 13
9. Insert->Header & Footer Tutorial / Demo 9 Wednesday, April 10, 13
10. Insert->Header & Footer Core Concepts 10 Wednesday, April 10, 13
11. Why Core Concepts •“How does my action controller get dispatched?” •“How do I create re-usable components/modules for my team/public consumption?” •“I’m just generally curious about the architecture.” 11 Wednesday, April 10, 13
12. 3 Central Components •Zend\Mvc composes: Zend\EventManager to build a workflow based on an event model Zend\ServiceManager for members in this workflow to consume and provide instances of objects Zend\ModuleManager to encapsulate members together 12 Wednesday, April 10, 13
13. Insert->Header & Footer Zend\EventManager 13 Wednesday, April 10, 13
14. Events •Some objects trigger an events •Some objects listen for events 14 Wednesday, April 10, 13
15. Terminology •An Event is both an action and a value object. •A Listener is a callback that accepts an Event and acts on it. •An Event Manager is an object that aggregates listeners for named events, and which triggers events. 15 Wednesday, April 10, 13
16. Example: Listener 16 Wednesday, April 10, 13
17. Example: Triggering 17 Wednesday, April 10, 13
18. Example: Implication 18 Wednesday, April 10, 13
19. Other Features •Shared listeners attach listeners even when you don't have the target instance •Priority specify the order in which listeners are triggered 19 Wednesday, April 10, 13
20. •Stop propagation from inside a listener, or based on the result of a listener •Aggregate and introspect listener results 20 Wednesday, April 10, 13
21. Insert->Header & Footer Zend\ServiceManager 21 Wednesday, April 10, 13
22. Services •Objects you work with (including Controllers!) •Substitutable, replaceable •Define how you want them built •Inversion of Control 22 Wednesday, April 10, 13
23. Types •Instances (services) •Constructor-less classes (invokables) •Factories when objects have dependencies (factories) •Factories for multiple related objects (abstract_factories) •Aliased services (aliases) •Automated initialization (initializers) 23 Wednesday, April 10, 13
24. Examples notes •Can be done programmatically •Or in Zend\Mvc Application: via configuration •(both shown) 24 Wednesday, April 10, 13
25. Instances 25 Wednesday, April 10, 13
26. Invokables 26 Wednesday, April 10, 13
27. Factories 27 Wednesday, April 10, 13
28. Abstract Factories 28 Wednesday, April 10, 13
29. Aliases 29 Wednesday, April 10, 13
30. Initializers 30 Wednesday, April 10, 13
31. ZF2 MVC Implications / Other Features •All plugin managers are service managers! You can now inject dependencies into helpers, plugins, etc! •Services are shared by default; you can disable this selectively •Manager "peering" is available 31 Wednesday, April 10, 13
32. Services Are Configurable •Application configuration •Module classes (we'll get to that...) •Module configuration •"Global" and "Local" override configuration 32 Wednesday, April 10, 13
33. Insert->Header & Footer Modules & Zend\ModuleManager 33 Wednesday, April 10, 13
34. What is a Module? •A named encapsulation of “stuff” •Provide the MVC with: Autoloading Configuration Services (including controllers, plugins, etc.) Event listeners / event wiring •Are reusable 34 Wednesday, April 10, 13
35. “stuff” •At least a namespaced “Module.php” •... anything: file assets classes mvc members 35 Wednesday, April 10, 13
36. Zend\ModuleManager •Loops through modules •Consumes the EventManager to: Triggers an event for each module allowing listeners to act on Module classes 36 Wednesday, April 10, 13
37. ModuleManager Events •loadModules: the loop in which modules are loaded •loadModule: triggered once we have a Module class instance •loadModules.post: to allow listeners to act on aggregated information from all Modules 37 Wednesday, April 10, 13
38. ModuleManager Built-in Listeners •AutoloaderListener •ConfigListener: aggregate config from all modules •ServiceListener: aggregate `ServiceManager` (and plugin manager) !configurations from Module classes and/or module configuration •OnBootstrapListener: register a Module as a "bootstrap" event listener !more ... including any you want to write 38 Wednesday, April 10, 13
39. Simple Example 39 Wednesday, April 10, 13
40. Insert->Header & Footer Zend\Mvc 40 Wednesday, April 10, 13
41. Zend\Mvc •Composes EventManager so that Everything is an Event 41 Wednesday, April 10, 13
42. Everything Is An Event 42 Wednesday, April 10, 13
43. The MVC Events •bootstrap •route •dispatch and dispatch.error •render (and, in 2.1, render.error) •finish •(These are actual event names) 43 Wednesday, April 10, 13
44. Mvc: Routing •Routing matches the Request to a Controller (really a set of parameters that the dispatch listener will use to marshall a controller) •Route definitions are a tree structure (i.e., routes can have child routes!) Zend\Mvc\Router implementation •(See Ben Scholzens Zendcon Router Slides) 44 Wednesday, April 10, 13
45. Mvc: Routing •Literal: /foo •Segment: /literal/:id[/:optional] •Regex:/literal(?P<id>[a-f0-9]{8}) •Scheme •Method •Wildcard 45 Wednesday, April 10, 13
46. Mvc: Controllers •Controllers are Services •Controllers must implement Zend\Stdlib \DispatchableInterface more useful to extend a base controller: •AbstractController •AbstractActionController •AbstractRestfulController 46 Wednesday, April 10, 13
47. 47 Wednesday, April 10, 13
48. Everything is a Module 48 Wednesday, April 10, 13
49. Philosophy •Models are still up to you to decide how to implement •More functionality can be found in 3rd party modules ... •so ......... 49 Wednesday, April 10, 13
