Agenda
• Introduction to Phing

• Continues Integration

• Deployment Strategy Examples

• Q&A


Hands Up!
• Who knows or uses build tools?

• Who is using Continues Integration?


Phing is not GNU make
• PHP build tool

• based on Apache Ant

• Originally developed by Binarycloud

• Ported to PHP5 by Hans Lellelid

• Lead is Michiel Rook


Why use build tools?
• We all hate repetition

• We forget things

• We make mistakes

• We have other things
todo

• Be independent of key
staff


Automate it!
• Helps developers, • Improve quality
testers, administrators
• Reduce errors
• Great for new team
members • Save time

• Consolidate scripts

• Standardize tasks

• Deﬁne task
dependencies


Installation
• Use PEAR
# pear channel-discover pear.phing.info
# pear install [--alldeps] phing/phing
• Download package
# http://www.phing.info/trac/wiki/Users/Download
• GIT
# git clone git://github.com/phingofﬁcial/phing.git


Phing Features
• Syntax Checks (PhpLint/JsLint)
• Testing (PHPUnit/SimpleTest)
• Static code analysis (pdepend)
• Version Control (SVN/GIT)
• Documentation (ApiGen/phpDox)
• File manipulation (mv/rm/chmod)
• Compression (Zip/Gzip)


XML Build File
<?xml version="1.0" encoding="UTF-8" ?>
<project name="php-git-wrapper" default="test">


<property name="src" value="${project.basedir}/php-git-wrapper" />
<property file="build.properties" />


<fileset dir="${src}/tests" id="tests">
<include name="**/*Test.php" />
<exclude name="**/Abstracts*.php" />
</fileset>


<target name="prepare" description="Prepare environment" />
<target name="test" depends="prepare" description="Start PHPUnit" />
<target name="document" description="Generate HTML documentation" />

</project>

Target List
# phing -l

Buildfile: /build.xml
[property] Loading /build.properties
Default target:
------------------------------------------------------
test Start PHPUnit Tests

Main targets:
------------------------------------------------------
document Generate HTML documentation
prepare Prepare environment
test Start PHPUnit Tests


A Closer Look

Extending Phing
• Tasks (copy, mkdir, camouﬂage, ...)

• Types (strings, integer, boolean, DSN, ...)

• Selectors (contain, date, ...)

• Filters (replace, stripwhitespace, ...)

• Mappers (glob, regexp, ...)

• Loggers (xml, html, ...)


Continues Integration
• Automated build tools

• Short integration phase

• High frequency

• Focus on testing

• Source is XP

Deployment
All of the activities that make a
software system available for use.

Packaging Distribution Installation


What matters
• Product • Dependencies

• Project • Code size

• Library • Conﬁguration
complexity
• Framework

• Open-Source

• Proprietary code


Where matters
• Self managed server • Cluster

• Local server (intranet) • Cloud

• Customer server • Appliance

• Multi platform

• Single host

• Server farm


Who matters
• Internal administrators

• DevOps

• Customers with IT
department

• Some developers

• Trained staff

• Anti geek


Deployment Strategies
Packaging Distribution Installation
• zip • version • ftp • zookeeper • shell scripts
control
• phar • scp • doozer • composer
• composer • rsync • noah • dep / apt-get
• pear • ssh • accord • rpm / yum
• web page • MS WPI
• chef /
puppet / juju
