The document discusses deploying PHP applications using Phing, a PHP project build tool that facilitates automation of repetitive tasks such as testing, version control, and database migrations. It explores the features of Phing, including XML build files, properties, file sets, filters, and its integration with PHPUnit for testing. Additionally, it highlights the extension capabilities of Phing and its potential future improvements.

11. Why Use Phing
Rich set of tasks
Integration with PHP specific tools
Allows you to stay in the PHP infrastructure
Easy to extend
Embed PHP code directly in the build file
... in the end, the choice is yours

12. The Basics
Deploying PHP applications with Phing – 11 / 37

13. Build Files
Phing uses XML build files
Contain standard elements
Task: code that performs a specific function (svn checkout, mkdir, etc.)
Target: groups of tasks, can optionally depend on other targets
Project: root node, contains multiple targets

14. Example Build File
<project name="Example" default="world">
<target name="hello">
<echo>Hello</echo>
</target>
<target name="world" depends="hello">
<echo>World!</echo>
</target>
</project>

15. Properties
Simple key-value files (.ini)
## build.properties
version=1.0
Can be expanded by using ${key} in the build file
$ phing -propertyfile build.properties ...
<project name="Example" default="default">
<property file="build.properties" />
<target name="default">
<echo>${version}</echo>
</target>
</project>

16. File Sets
Constructs a group of files to process
Supported by most tasks
<fileset dir="./application" includes="**"/>
<fileset dir="./application">
<include name="**/*.php" />
<exclude name="**/*Test.php" />
</fileset>
Supports references
<fileset dir="./application" includes="**" id="files"/>
<fileset refid="files"/>

17. File Sets
Selectors allow fine-grained matching on certain attributes
contains, date, file name & size, ...
<fileset dir="${dist}">
<and>
<filename name="**"/>
<date datetime="01/01/2011" when="before"/>
</and>
</fileset>

18. Mappers and Filters
Transform files during copy/move/...
Mappers
Change filename
Filters
Strip comments, white space
Replace values
Perform XSLT transformation
Translation (i18n)

19. Mappers and Filters
<copy todir="${build}">
<fileset refid="files"/>
<mapper type="glob" from="*.txt" to="*.new.txt"/>
<filterchain>
<replaceregexp>
<regexp pattern="rn" replace="n"/>
<expandproperties/>
</replaceregexp>
</filterchain>
</copy>

Apply & undo statements
--//
CREATE TABLE ‘post‘ (
‘title‘ VARCHAR(255),
‘time_created‘ DATETIME,
‘content‘ MEDIUMTEXT
);
--//@UNDO
DROP TABLE ‘post‘;
--//

<option name="outputdirectory" value="./build"/>
<option name="description">Test package</option>
<option name="version" value="0.1.0"/>

<mapping name="maintainers">
<element>
<element key="handle" value="test"/>
<element key="name" value="Test"/>
<element key="email" value="test@test.nl"/>

basedir="build"/>
... or ZIP
<zip destfile="htmlfiles.zip">
<fileset dir=".">
<include name="**/*.html"/>
</fileset>
</zip>

34. Ad Hoc Extension
Define a task within your build file
<target name="main">
<adhoc-task name="foo"><![CDATA[
class FooTest extends Task {
private $bar;
function setBar($bar) {
$this->bar = $bar;
}
function main() {
$this->log("In FooTest: " . $this->bar);
}
}
]]></adhoc-task>
<foo bar="TEST"/>
</target>
