PHP rocks !


Higher Quality

design patterns

coding standards

development methodologies (agile, scrum, …)

version control (CVS, Subversion, GIT, …)

documentation

unit testing (PHPUnit, SimpleTest, PHPT)


Design Patterns

a solution to common coding challenges

tried and tested

specific “lingo” for developers

increases readability of code


Coding Standards

increase readability of code

consistent code usage by each developer

easier detection of flaws and security holes

a must for corporate/enterprise development


Dev Methodologies

improvement of a development job

better understanding of

project’s scope

project’s lifetime

immediate feedback


Version Control

keeps track of changes of the codemerges changes on same code base(when some developers change same file)multiple versions exists in branchesenables release managementrevert back in case of errorsprovides a back up


Documentation

in-code documentation (doc blocks)used for API documentation (PHPDocumentator)

end user documentationxml for DocBookwiki on intranet/extranet/interneta digital document as reference


Why test ?

behaves the code as expected ?

triggers exceptions when it should ?

are security issues tackled ?

is a reported issue a valid one ?

where am I in my project (TDD) ?


Testing

I pity the fool who doesn’t write tests!


Benefits of testing

more testing == less debugging!

applications should work as expected

actually takes less time

provides higher quality

easier to refactor and change

makes confident developers


Testing


Get Certified

Zend PHP 5 certification

Zend Framework Certification

Why:

Differentiate when looking for a job

Get listed in Zend Yellow Pages

Confirmation of a decent PHP skill set
