Sebastian Bergmann mentions today about a feature in an upcoming release of a popuular unit testing tool for PHP, PHPUnit - the addition of more software metrics.

The upcoming 3.1.6 release of PHPUnit adds a couple of software metrics to the data that is stored in PHPUnit's test database. Among these metrics is the Cyclomatic Complexity Number (CCN).

An example of how the CCN works is shown in the post giving the className, methodName and the complexity ranking given for the combination. His example shows the rankings for a part of the eZ Components software.
