Using Different Loggers In Phing

17th November 2009

When you run a phing script it will print things out to the console. These messages are either system messages (eg. BUILD STARTED) or echo messages that you have put into your build.xml file. All of this output is controlled and created by a logger file. The default logger is called (unsuprsingly) DefaultLogger and will be used as a default. There are a few different types of logger available, all of which can be found in the listener folder in your PEAR\phing directory.

Integrating Phing With PHPUnit

16th January 2009

PHPUnit is a unit testing framework, written in PHP, and which is used to test PHP code. You can integrate the testing that PHPUnit does into Phing. You might want to use Phing to create a nightly build that contains the latest version of your program. The last thing you want is Phing to create a nightly build that is riddled with errors.

The way around this is to use PHPUnit to test our code whilst we are running Phing. If any tests fail then Phing will not finish the build.

Create Compressed Files With Phing

15th January 2009

Building your projects into directories is nice, but distributing these projects is difficult if you have to build the compressed files yourself. Phing has the ability to create zip and tar files using simple commands.

The most convenient way of using the tar and zip commands is by using a fileset. But rather than use the fileset that was used to copy the files into the build directory it is best to create a separate fileset that is used to compress the contents of the build directory.

Create A File Or Directory With Phing

14th January 2009

After following the last post on deleting files and directories in Phing you might now be wondering if you can create things as well. The answer is yes.

To create a directory with Phing you need to use the mkdir element. The dir attribute is used to give the name of the directory to be created. The following example will create a directory called myProject_build in the current working directory (ie. where you are running phing from).

Deleting Directories With Phing

13th January 2009

Although using Phing is mainly about copying files, you might also need to delete directories and files using the delete element. Remember that the default behavior of copy command copies files only if the source files are different from the destination files. A prudent approach might be to delete the build directory and then recreate it, ready for Phing to copy files into.

FilterChain Element In Phing

12th January 2009

The FilterChain element is where the power of Phing really comes into its own. This element will allow you to change the contents of the files of a fileset. This can range from a simple stripping of comments, to replacing values and numerous other filters.

One of the simplest thing that can be done with filterset is to strip all comments from the files in question. Take the following PHP file with two comments.

Built In Properties In Phing

Aside from assigning and using your own properties Phing also comes with a set of built in properties that can be used to find out all sorts of information regarding the system that Phing is run on.

As an example, lets say you wanted to found out the operating system that phing is being run on. In this case you would use the variable host.os, which on a Windows XP system would print out WINNT.

Using Custom Properties In Phing

8th January 2009

Phing allows you to set up certain parameters that can be used throughout the rest of the script. These might be used to define a non standard build directory, or to store database connection details that can be written to the connection file during the build.

Properties are defined using the property element, which you should place at the top of your build.xml file in order to make it easy for other developers to see what is going on. The following example defines a property and the uses the main target to print the property out.

Using Patternset With Fileset In Phing

7th January 2009

When a project gets complicated then so to can the build.xml file associated with it. You might find it necessary to have multiple different filesets, each of which do something different, but all of which have the same core files that they use. Multiple filesets are useful if you want to create a version of your project with all of the testing files in place so that it can be tested by external developers.

Copying Files Using Phing

6th January 2009

One of the main reasons to use Phing is to create a copy of your project in another directory that you can then use as your distribution copy. Your working directory might contain lots of testing code that is not needed in the final build.

To copy a file from one directory to another using Phing you need to use the copy element. Here is a simple example where a single file is copied from one directory to another.
