Once you're done coding, the project is all but finished. There are lots of tools to keep control over your code outside your IDE. Especially continuous integration tools are really helpfull for this purpose. Under the hood of a CI, or at commandline, Phing can be used for lots of PHP specific tasks that are usually executed within a CI. Phing is a sort of PHP version of the Apache Ant tool, which is neatly integrated with some handy PEAR packages. During this presentation you'll get a basic understanding about Phing and its features. We will walk through some examples and screens, so you get some basic knowledge about phing and in what type of fields it can be really usefull.

4. What is Phing
 Phing homepage: http://phing.info
“PHing Is Not GNU make; it's a PHP project
build system or build tool based on Apache Ant”
 Phing is like a jigsaw
puzzle. It has a lots
of easy to use building
blocks to cover everything
between a code base and
a live production
environment

5. Why using Phing
 Phing homepage:
“If you find yourself writing custom scripts to
handle the packaging, deploying, or testing of
your applications”
 A shared platform that is maintained →
less programming && less communication with
(new) developers I'm not needed,
so I can be empty
“An excellent developer
makes himself needless”

6. Features
In a nutshell

7. Example deployment
 “Phing look and feel” Info target
 e-sites library (ESL)
 Deploy ESL
 Revert version

8. <?xml version="1.0" encoding="UTF-8"?>
Deployment code
<project name="ESL" default="info">
<target name="deployMinor">
<version releasetype="Minor" file="VERSION" property="version"/>
<svncommit workingcopy="." message="Updated VERSION file to ${version}" username="user" password="password"/>
<svncopy repositoryurl="http://svn.dev/library/esl/Branches/v1" todir="http://svn.dev/library/esl/Tags/release-${version}" username="user"
password="password"/>
<svnupdate todir="." username="user" password="password"/>
<phingcall target="deploy"/>
</target>
<target name="deploy" description="Deploy ESL" depends="tarball">
<fail unless="version" message="Please specify version to export e.g. -Dversion=1.0.0" />
<phingcall target="deployserver">
<property name="host" value="dev"/>
</phingcall>
<!-- clean up mess →
<delete dir="/tmp/eslpackage" quiet="true"/>
</target>
<target name="tarball">
<fail unless="version" message="Please specify version to export e.g. -Dversion=1.0.0" />
<!-- this is to check if SVN tag exists →
<svnlastrevision repositoryurl="http://svn.dev/library/esl/Tags/release-${version}" propertyname="tag" username="user" password="password"/>
<property name="build.dir" value="/tmp/eslpackage" />
<delete dir="${build.dir}" quiet="true"/>
<svnexport username="user" password="password" repositoryurl="http://svn.dev/library/esl/Tags/release-${version}" todir="${build.dir}"/>
<delete file="${build.dir}/build.xml"/>
<tar destfile="/tmp/eslpackage/esl.tar" compression="gzip">
<fileset dir="${build.dir}">
<include name="**/**" />
</fileset>
</tar>
</target>
<target name="deployserver" if="host,version">
<scp username="esites" host="${host}" todir="/tmp" file="/tmp/eslpackage/esl.tar" pubkeyfile="/var/www/.ssh/id_rsa.pub"
privkeyfile="/var/www/.ssh/id_rsa"/>
<!-- untar and symlink →
<ssh username="esites" host="${host}" command="mkdir /var/www/includes/ESL-${version}; cd /var/www/includes/ESL-${version}; tar -zvxf /tmp/esl.tar; ln
-s ./ESL-${version} /var/www/includes/ESLv1_tmp; mv -Tf /var/www/includes/ESLv1_tmp /var/www/includes/ESLv1;rm -f /tmp/esl.tar"
pubkeyfile="/var/www/.ssh/id_rsa.pub" privkeyfile="/var/www/.ssh/id_rsa"/>
</target>

9. Phing and CI
 Example with Jenkins (Hudson) “building ESL”
 Execute unit tests
 Codesniffer for standards
 PHPMD for mess detection
 Code coverage report for unit test
 PHPDepend stats
+

10. <?xml version="1.0" encoding="UTF-8"?>
<project name="ESL">
<target name="build" description="Build ESL">
Jenkins build file
<mkdir dir="./reports"/>
<fileset dir="./ESL" id="php.fileset">
<include name="**/*.php"/>
</fileset>
<!-- Set up coverage db →
<coverage-setup database="./reports/coverage.db">
<fileset refid="php.fileset"/>
</coverage-setup>
<!-- Execute unit tests →
<phpunit bootstrap="./bootstrap.php" codecoverage="true">
<formatter type="clover" todir="reports"/>
<formatter type="xml" todir="reports"/>
<batchtest>
<fileset id="unittests" dir="./tests">
<include name="**/*Test.php"/>
</fileset>
</batchtest>
</phpunit>
<!-- Do codesniffing →
<phpcodesniffer standard="Esites" format="checkstyle">
<fileset refid="php.fileset"/>
<formatter type="checkstyle" outfile="./reports/checkstyle.xml"/>
</phpcodesniffer>
<!-- Do PMD checks →
<phpmd rulesets="Esites">
<fileset refid="php.fileset"/>
<formatter type="xml" outfile="./reports/pmd.xml"/>
</phpmd>
<!-- Copy paste detection →
<phpcpd>
<fileset refid="php.fileset"/>
<formatter type="pmd" outfile="./reports/cpd.xml"/>
</phpcpd>
<!-- Get PHPDepend stats →
<phpdepend>
<fileset refid="php.fileset"/>
<logger type="jdepend-xml" outfile="./reports/jdepend.xml"/>
<logger type="jdepend-chart" outfile="./reports/dependencies.svg"/>
<logger type="overview-pyramid" outfile="./reports/overview-pyramid.svg"/>
<analyzer type="coderank-mode" value="method"/>
</phpdepend>
</target>
</project>

12. Extending Phing
 Example
Existing SSH task is incomplete. We want
to capture SSH output for string matching
 Add your task/class to defaults.properties
 Create user directory in tasks
 Create your own task with setters and
main method

13. <?xml version="1.0" encoding="UTF-8"?>
Custom task
<project name="ESL" default="build">
<property name="dir.source" value="/var/www/html/workingcopies/mdkrijger/personal/esltest" />
<property name="dir.destination" value="/tmp/phingdemo" />
<target name="compare" description="Compare 2 fixed directories">
<!-- Create package (tarball) →
<tar destfile="tarball.tar" compression="gzip">
<fileset dir="${dir.source}">
<include name="**/**" />
</fileset>
</tar>
<!-- upload it to production environment →
<scp username="esites" host="dev" todir="/tmp" file="tarball.tar" pubkeyfile="/var/www/.ssh/id_rsa.pub" privkeyfile="/var/www/.ssh/id_rsa"/>
<!-- Extract the uploaded image, display its activity →
<ssh username="esites" host="dev" command="mkdir /tmp/phingdemo; cd /tmp/phingdemo; tar -zxvf /tmp/tarball.tar"
pubkeyfile="/var/www/.ssh/id_rsa.pub" privkeyfile="/var/www/.ssh/id_rsa"/>
<!-- This is the custom task →
<!-- get directory sizes →
<sshterm username="esites" host="devlocal" display="false" property="size1" command="du -bs ${dir.destination} | egrep -o '([0-9]*)'"
pubkeyfile="/var/www/.ssh/id_rsa.pub" privkeyfile="/var/www/.ssh/id_rsa"/>
<exec command="du -bs ${dir.source} | egrep -o '([0-9]*)'" outputproperty="size2"/>
<!-- compare them →
<if>
<not>
<equals arg1="${size1}" arg2="${size2}"/>
</not>
<then>
<fail message="Directories are not in sync! Size source: ${size2}, Size destination: ${size1}"/>
</then>
<else>
<echo message="Directories are in sync"/>
</else>
</if>
</target>
<target name="clean">
<delete dir="/tmp/phingdemo"/>
<delete file="/tmp/tarball.tar"/>
</target>
<target name="break">
<copy file="/tmp/tarball.tar" tofile="${dir.destination}/tarball.tar" overwrite="true"/>
</target>
</project>
