The document discusses various PHP power tools that can be used to improve code quality, including syntax checkers (PHPLint), documentation generators (PHPDocumentor), coding standard checkers (PHP_CodeSniffer), copy/paste detectors (PHPCPD), and dependency/complexity analyzers (PDepend, PHPMD). It also presents Phing, an automation tool that can integrate these tools into a single automated build process, and demonstrates running Phing targets to generate reports from tools like PHP_CodeSniffer, PDepend, and PHPMD. The presentation emphasizes that using these tools can help produce cleaner, more consistent code and improve knowledge of a codebase.

3. Why PHP Power Tools
• early detection of issues
• cleaner & consistent code
• knowledge about the codebase
• better code

4. Usual Suspects
PHP_CodeSniffer

5. Example Code
•- Zend Framework QuickStart app
http://framework.zend.com/manual/en/learning.quickstart.intro.html

6. VirtualHost Settings
<VirtualHost *:80>

8. Syntax Checking
•- PHPLint
comes with PHP binary
- validates code for syntax errors
• Website
- http://www.icosaedro.it/phplint/

9. Demo PHPLint

10. Code Documentation
•- PHPDocumentator
creates automated API documentation
- based on inline code blocks
• Installation
- pear install PhpDocumentor
• Website
- http://www.phpdoc.org

11. Demo PHPDoc

12. Output PHPDoc

13. Coding Standards
•- PHP_CodeSniffer
sniffs for coding standard violations
- ensures code is clean and consistent
- using standard and custom coding standards
• Installation
- pear install PHP_CodeSniffer
• Website
- http://pear.php.net/package/PHP_CodeSniffer

14. Demo PHP_CodeSniffer

15. PHPCPD
•- PHP Copy/Paste Detector
detects code duplication
•- Installation
pear channel-discover pear.phpunit.de
- pear channel-discover components.ez.no
- pear install --alldeps phpunit/phpcpd
• Website
- http://github.com/sebastianbergmann/phpcpd

16. Demo PHPCPD

17. Output

18. Mess Detection
•- PDepend & PHPMD
detects code mess
•- Installation
pear channel-discover pear.pdepend.org
- pear install pdepend/PHP_Depend
- pear channel-discover pear.phpmd.org
- pear install phpmd/PHP_PMD
• Websites
- http://www.pdepend.org
- http://www.phpmd.org

19. Demo detecting mess

20. Output codesize

21. Output unused code

22. Unit Testing
•- PHPUnit
tests code on unit level
- includes database tests
- integrates well with many PHP frameworks
• Installation
- pear channel-discover pear.phpunit.de
- pear install phpunit/PHPUnit
• Website
- http://www.phpunit.de

23. See other presentation

24. Automated builds
•- Phing
automated build tool
- like Apache Ant
- integrates well with other PHP tools
• Installation
- pear channel-discover pear.phing.info
- pear install phing/phing
• Website
- http://phing.info
