Presentation for Codeworks 2012 Atlanta. This presentation went through what Phing is, how to set it up, example, and how we implemented it with our applications.

1. Presented by Joey Rivera

2. Introduction

• Manger of Technology Development at
Cengage Learning

3. Summary
• Why we need Phing
• Installing and Usage
• Extending
• Examples
• Our implementations

4. Problem
http://www.seniorark.com/Humor/Double%20Takes/crooked%20line.gif

5. Problem Cont.
• We make mistakes
• Manual process can be time consuming
• Busy work is no fun

6. Our Goals
• Identify manual process at work
– daily, weekly, monthly processes
• Analyze amount of time spent on those
• Automate them

7. Our Before

8. Our After

9. Phing is
• PHing Is Not GNU make
• Build tool based on Ant
• XML based build files
• Written in PHP5
• Flexible and extendable
• Platform independent

10. Why Phing
• Automation
• Save time
• Less errors
• Tons of built-in
tasks and features

11. Install
• http://www.phing.info
• PEAR install
– pear channel-discover pear.phing.info
– pear install phing/phing
– Get necessary dependencies
• Non-PEAR Install
– Download
– Configure multiple env variables

12. Dependencies
http://www.phing.info/docs/guide/stable/

13. Using Phing
• Command line
– phing -v
– phing -f buildfile
– phing -f buildfile targetname
– phing
– phing -l
– phing -debug

14. Build File
• XML file
– Project
– Targets
– Tasks
– Types and properties
– Filters
– Mappers
– Conditions

15. Example Build File
http://www.phing.info/docs/guide/stable/

16. Project Node
• Requires one per build.xml
• Requires a default target declaration
• Optional attributes:
– name
– basedir
– description

17. Targets
• Grouping of tasks
• Can depend on other tasks

18. Tasks
• Single piece of executable
code
• Core:
– Copy, Delete, Echo, Exec, Mo
ve, Foreach, and more
• Optional:
– FtpDeploy, GitPush, PDOSQL
Exec, Scp, Zip, and more

19. Properties
• Variables
• global vs. target specific
• Declaration
– inline
– external file
– input

20. Built-in Properties
http://www.phing.info/docs/guide/stable/

21. Property File
• Text file Example:
• Good way to
organize variables
into one location
• Useful for
environment specific
files

22. Types
• Used within a task Example:
• More complex data
variables
– FileSet
• PatternSet
• * vs. **
– Excludes

23. Filters and Mappers
• Filters Transform data/file contents within a task
– Tidy
– ExpandProperty
– StripPhpComments
• Mappers are like filters for files and directories
– Flatten
– Glob
– RegExp

24. Conditions
• Used through the following
two tasks: Example:
– condition
– if
• Compare using
– equals
– isset
– contrains
– istrue
– available
• Can nest
– or
– and
– not

25. Extending $PHING_HOME
|-- bin
|-- classes
• Can extend | `-- phing
| |-- filters
| | `-- util
– Tasks | |-- mappers
– Types |
|
|-- parser
|-- tasks
– Mappers | | |-- ext
| | |-- system
– Ad hoc | | | `-- condition
| | `-- user
| `-- types
|-- docs
| `-- phing_guide
`-- test
|-- classes
`-- etc

26. Custom Task
http://www.phing.info/docs/guide/stable/

27. Examples
• Version Control
• Packaging
• Unit Testing
• Documentation
• Deployment
• DbDeploy
• Exec

28. Version Control
• SVN
• Git

29. Packaging
• Tar
• Zip
• PharPackage

30. Unit Testing
• PhpUnit
• PhpUnitReport

31. Documentation
• PhpDocumentor2
– http://www.phpdoc.org/

32. Documentation Cont.

33. Deploying
• Copy
• Scp
• FtpDeploy

34. Database Deployment
• DbDeploy
– Database change management tool
– Creates script file based on deltas
– Tracks db version
– Easy to move version forward or backwards
– http://dbdeploy.com/

35. DbDeploy cont.
• Create changelog table
http://www.phing.info/docs/guide/stable/

36. DbDeploy Example
Deltas – each representing Deploy file after running DbDeploy
a version

37. DbDeploy Delta Example

38. Other
• Exec
– Can run any system command
– OS specific

39. Our Implementation
• Restoring our DB’s
• Automate SVN Exports
• Automate Tagging

40. Restoring DB’s
• Dev, Test, Staging, QA, Prod
• Environment specific data

41. Automate SVN Exports
• Trunk to Dev
– Export diff between last
rev and newest rev
• ‘Release’ Branch to
Testing
– Export diff between last
rev and newest rev
• Tag to
Staging, QA, Prod
– Export diff between last
tag and newest tag

42. Tagging
• From branch to Tag
– Diff between rev of last
release and last tag of
the same iteration
