PHP Framework Battle

The document presents a tech talk on PHP frameworks led by Zakir Hemraj, covering an overview of various frameworks, their basic concepts, and comparisons. It highlights the strengths and weaknesses of frameworks like Zend, CodeIgniter, and CakePHP, along with performance metrics from benchmark tests. The goal is to equip developers with knowledge to choose the right framework for their needs without an in-depth code walkthrough.
PHP Framework Battle
- 1. PHP Framework “Battle” Zakir Hemraj
- 2. • Slides and code will be posted on the meetup group • Video will be posted on: achievers.com/tech • Tell your friends!
- 3. About Me • Dev Team Lead @ Achievers • Professional Web Framework Experience: – J2EE with Spring, Hibernate – PHP with CodeIgniter – Ruby on Rails • Not an expert in Zend Framework, CakePHP or Symfony
- 6. Goal 1. Give you “flavor” of a few frameworks 2. Share some scientific and subjective comparisons 3. Make you better equipped to compare and choose the right framework
- 7. What I’m not doing… • In-depth framework code walkthrough of all features and functions • Handing you a silver bullet
- 8. Agenda 1. Overview of frameworks 2. Review basic concepts – MVC, ORMs 3. The application – requirements, db schema 4. Code walkthrough 5. Performance and other comparisons 6. Final thoughts

- 11. “You can write shitty code in any language, any framework”
- 12. Review - MVC Source: http://en.wikipedia.org/wiki/Model%E2%80%93view%E2%80%93controller • Most web frameworks are MVC these days • Lots of inconsistencies with the “model” layer HTTP Request HTML Business Logic & DB Access
- 13. Review - ORM • Object Relational Mapping • Maps database records to objects • 1-to-1 table to object class – E.g. job table -> job class • Layer of abstraction to: – Make code more maintainable – Enable stronger OO programming class TechTalk{ } table: tech_talk O R M
- 14. Now What?
- 15. The Application • A basic job board where people can: – Add jobs – View a listing of jobs – Look at a post in more detail • So simple, you could probably code it in your sleep
- 16. The Schema
- 17. Setup 1. Download framework * 2. Configure your app with your db 3. Point your web server to the directory (i.e. vhost in apache) 4. Start coding
- 19. Zend Code Summary • Nice command line tools -> less typing • Hard object instantiations play nice with IDE • Good, OO separation of layers, including db access, business logic, and forms • Cons: We’ll discuss later ;)
- 21. CI Code Summary • Super lightweight • Very few conventions or “magic” – Doesn’t force things on you – Very explicit • Lots of well documented tools and libraries
- 23. CAKE Summary • Rails-like convention over configuration • Very powerful, with convenient tools like scaffolding and strong relational mapping • Lots of “magic” that you need to be aware of
- 25. Documentation • Zend: – Complete, but fragmented – hard to follow. • CI – Great • CAKE – Outstanding
- 26. Other Comparisons Zend CI CAKE i18n Y Y Y unit testing Y N * Y templating Y Y * Y security utils Y Y Y authentication Y N Y caching Y Y Y
- 27. Performance • Source: http://www.ruilog.com/blog/view/b6f0e42cf7 05.html • Simple MVC logic, no DB connection • See site for full hardware specs

- 34. AND LASTLY…
- 35. My Two Cents • Too much abstraction is bad • Understand the tradeoffs • You will need to break out of the framework • Stay curious
Editor's Notes
- #5: -PHP Developers? -Experience with Zend, Cake, CodeIgniter, RoR, J2EE frameworks?-Had to choose a web framework for your company
- #6: Choosing a web frameworkis a lot like this. Claims to be:More enjoyable to useBetter securityBetter layers of separation
- #10: ZendRun by Zend technologiesCakeStarted in 2005Modeled on RoRIn 2009, some members left to start the Lithium framework
- #11: All frameworks “work” and have their benefitsThe reality is that
- #15: Poll audience -> what things do you look for
- #17: MySQLUsually would use singular labels for table nameInts, varchars, and datetime
- #19: Zend topics to cover:Zend command line utilities (zf)zf create project jobs_zendModel layerDifference between model and db_tablezf create model xzf create db-table job jobs (or create test)db tabledb table objects have built in functions and are 1-to-1 to tables (but not necessarily an orm). Simple DAOs. Override variables that define table, primary, and other options.Can write custom “queries” in db table objectsModelsMeant to encapsulate business logicDon’t extend anythingStrong object declaration makes for good IDE experienceIntroduce skinny controller, fat model ControllerIndex Contoller is defaultNaming conventions -> xAction, and url patterns -> not that cleanViewsBasic manipulation of dataSide notes:-good separation of staging, production, etc. out of the box
- #27: Go to wikipedia framework comparisons if you want more
- #36: AbstractionJavascript and html abstraction can lead to problems, working around framework to get what you wantQuery abstraction from ORM should be used with cautionTradeoffsRAD frameworks with lots of magic have their benefits, but also abstract devs from underlying performance issuesLite frameworks offer great performance, but you need to develop your own standards, especially for your own teamsBreakout-For almost any serious application, you’ll need to change or modify something about the framework-At Achievers, we needed to modify CI routing, logging, application loading, security filtering, etc. Understand the extendability of your applicationStay curiousLook under the covers always, and don’t be scaredUnderstand what’s happening behind the scenesUltimately, it’s the developer, not the framework
