Phing for Deployment

Phing (a recursive acronym, for Phing Is Not GNU make) is a way of automating the deploy-

ment of your PHP applications. It lets you run unit tests in an automated manner and perform

common tasks like copying files between folders.

Installing Phing

First, you need to install Phing, which you can do through PEAR:

> pear channel-discover pear.phing.info

Adding Channel "pear.phing.info" succeeded

Discovery of channel "pear.phing.info" succeeded

> pear install phing/phing

phing/phing can optionally use package

"pear/VersionControl_SVN" (version >= 0.3.0alpha1)

Starting to download phing-2.3.0beta1.tgz (397,990 bytes)

........................done: 397,990 bytes

install ok: channel://pear.phing.info/phing-2.3.0beta1

At this point, Phing is installed. Since you’re working with Subversion, and Phing optionally

supports Subversion, you should get the PEAR VersionControl_SVN package, too. You could try

to use pear install pear/VersionControl_SVN, but since it is an alpha package, you will probably

get an error like the following:

> pear install pear/VersionControl_SVN

Failed to download pear/VersionControl_SVN within preferred state "stable",

latest release is version 0.3.1, stability "alpha", use

"channel://pear.php.net/VersionControl_SVN-0.3.1" to install

Cannot initialize 'pear/VersionControl_SVN', invalid or missing package file

Package "pear/VersionControl_SVN" is not valid

install failed

So, instead, you must install it using the full-channel URI:

> pear install channel://pear.php.net/VersionControl_SVN-0.3.1

downloading VersionControl_SVN-0.3.1.tgz ...

Starting to download VersionControl_SVN-0.3.1.tgz (33,483 bytes)

.........done: 33,483 bytes

install ok: channel://pear.php.net/VersionControl_SVN-0.3.1

Now, with the PEAR packages installed, it’s time to write your first build file.
