PHP Industrialization
The document discusses the industrialization of PHP development, emphasizing the need for efficient coding practices, code refactoring, and the use of version control systems. It outlines a three-stage approach to scaling PHP applications, which includes conventions, frameworks, unit testing, and continuous integration. Additionally, it highlights the importance of documentation, agile methodologies, and collaboration in software development.

- 11. PHP industrialization Goingfrom single to multiple Being proactive, rather than reactive Scale your work, not your server Otherwise, go to Rasmus session
- 12.
- 13. Conventions PEAR, Zend Frameworks, Symfony... Choose one, useone Bring unity Code_sniffer
- 14. IDE Choose it forease of use Netbean / Symfony, Zend tools, Komodo / cakePHP Code browser, editor, debugger, unit test integration, VCS integration, framework integration.
- 15. VCS Subversion, git, CVS,bazaar Resolve conflicts Stores and distribute the code Allow versioning, paralell development, rollback Code not in VCS does not exists
- 16. VCS Code Bug Track Production VCS Continuous Unit Test integration
- 17. Recommanded sessions Clean Code/ Zend Framework
- 18.
- 19. Methodologies Explain how youproduce code Get your users involved Make short cycles to deliver, adapt and polish Agile methodologies : SCRUM, XP, Lean SD, Open Unified Process
- 20.
- 21. Frameworks Frameworks Choose one,for development speed Components, conventions, scafolding, tests Community, expertise, training
- 22. Unit Tests PHPUnit, Simple Test, Lemon, Zend_Test, phpt
- 23. Tests helps decouple Production Avoid regression Code Platform Prevent your recall Shows progress Serves as manual Help at communication Customer use
- 24. Functional tests GreenPepper,Fitnesse
- 25. Recommanded sessions Agile developmentfor PHP, SCRUM con exito Symfony 2.0 State of quality assurance tools
- 26.
- 27. Automated deployment Phing, maven,ant, pear Needed for continuous integration The forgotten part of development Compulsory for large plat-forms, high scaling
- 28. Continuous integration Checkthe code in back ground phpUnderControl, Xinc, Hudson Graphs the results Compilation, code sniffer, unit tests, coverage Log, inclusion, performances... Share with the team
- 30. Conception Class diagram, databaseschema, navigation ArgoUML, StarUML, PowerArchitect Describe the general organisation List everything that will need name Class, methods, constants, SESSION, includes... Check the result
- 31. Conception Document things beforehand Auto-generate phpdoc Check usage in the code, check undocumented
- 32. Documentation From developper tousers Have developper start it Add comments Turn it into a wiki
- 33. Recommanded sessions Tallar dePHING Continuous integration
- 34. Even further? Continuousdeployment (a la flickr) Cross auditing Collaborative auditing Static analysis
- 35. Most tools comefrom Java Hudson / Xinc Junit / PHPUnit CheckStyle / Code Sniffer UML to PHP (but not the reverse) Static audit analysis? Code navigation ? Code audit tool ? almost...

- 39. Documentation Level 0 :in code Level 1 : automated, manual PHPdoc, PHPdocumentor, Doxygen Level 2 : Wiki, blogues Level 3 : books, conferences
- 40. Scaling up coding Domore Leave part of it to others
- 41. Handling bugs Level 1: manual test before production Level 2 : automate tests before production Level 3 : hand out tests to functional
- 42. Tools Firefox, Web Developper PHPUnit, Simple Tests, phpt, Push 2 Test GreenPepper, Fitnesse
- 43. More tests Get moretests Hand them to your users Use them in requirements Use them for docs
- 44. Team Conception à cyclescourts Conventions de programmation Mantras de programmation Audits croisés
- 45.
- 46. Progression Tests unitaires Tests fonctionnels Intégrationcontinue Documentation automatique Suivi des conventions
- 47.
- 48. Avoid dead endtools Writing comments that are rarely read Producing doc ? Reusing unit tests ?
- 49. Scale up yourwork direct communication is OK for 2 mail is OK for 4 mantis is better
- 50. Aspects Automation API,PHPUnit, Including users in the tests Standards (SOAP/WSDL)
- 51. 3 phases ofevolution Experimentation Mission critical Strategy
- 52. Approach of coding We’lldo what we need We’ll gather in the end to make this a good library This shows a lack of anticipation
