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.
