Software metrics supported by PHP_Depend
PHP Depend can generate a large set of software metrics from a given code base, these values can be used to measure the quality of a software project and they help to identify that parts of an application where a refactoring should be applied.
This section will give a brief overview of the software metrics provided by PHP Depend and it tries to give an introduction how to interpret them in the context of an application's code base.
