Summary

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

Problem

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

Problem Cont.

• We make mistakes• Manual process can be time

consuming• Busy work is no fun

Our Goals

• Identify manual process at work– daily, weekly, monthly processes

• Analyze amount of time spent on those

• Automate them

Our Before

Our After

Phing is

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

Why Phing

• Automation• Save time• Less errors• Tons of built-in

tasks and features

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

Dependencies

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

Using Phing

• Command line– phing -v – phing -f buildfile– phing -f buildfile targetname– phing– phing -l– phing -debug

Build File

• XML file– Project – Targets– Tasks– Types and properties– Filters–Mappers– Conditions

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

Example Build File

Project Node

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

Targets

• Grouping of tasks• Can depend on other tasks

Tasks

• Single piece of executable code• Core:

– Copy, Delete, Echo, Exec, Move, Foreach, and more

• Optional:– FtpDeploy, GitPush, PDOSQLExec,

Scp, Zip, and more

Properties

• Variables• global vs. target specific• Declaration

– inline– external file– input

Built-in Properties

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

Property File

• Text file• Good way to

organize variables into one location

• Useful for environment specific files

Example:

Types

• Used within a task• More complex

data variables– FileSet• PatternSet• * vs. **

– Excludes

Example:

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

Conditions

• Used through the following two tasks:– condition– if

• Compare using– equals– isset– contrains– istrue– available

• Can nest– or– and– not

Example:

Extending

• Can extend– Tasks– Types–Mappers– Ad hoc

$PHING_HOME |-- bin |-- classes | `-- phing | |-- filters | | `-- util | |-- mappers | |-- parser | |-- tasks | | |-- ext | | |-- system | | | `-- condition | | `-- user | `-- types |-- docs | `-- phing_guide `-- test |-- classes

`-- etc

Custom Task

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

Examples

• Version Control• Packaging• Unit Testing• Documentation• Deployment• DbDeploy• Exec

Version Control

• SVN• Git

Packaging

• Tar• Zip• PharPackage

Unit Testing

• PhpUnit• PhpUnitReport

Documentation

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

Documentation Cont.

Deploying

• Copy• Scp• FtpDeploy

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/

DbDeploy cont.

• Create changelog table

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

DbDeploy Example

Deltas – each representing a version

Deploy file after running DbDeploy

DbDeploy Delta Example

Other

• Exec– Can run any system command– OS specific

Our Implementation

• Restoring our DB’s• Automate SVN Exports• Automate Tagging

Restoring DB’s

• Dev, Test, Staging, QA, Prod• Environment specific data

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

Tagging

• From branch to Tag– Diff between rev of

last release and last tag of the same iteration
