PHP Depend - Software Metrics for PHP

Usage

You should test that PHP_Depend was correctly installed and can be used from the command line:

~ $ pdepend --version PHP_Depend 0.9.4 by Manuel Pichler

Now that PHP_Depend was installed correct and works, run PHP_Depend against its own source and generate a xml report and some charts.

~ $ pdepend --summary-xml=/tmp/summary.xml \ --jdepend-chart=/tmp/jdepend.svg \ --overview-pyramid=/tmp/pyramid.svg \ /usr/local/share/pear/PDepend PHP_Depend 0.9.4 by Manuel Pichler Parsing source files: ............................................................ 60 ............................ 88 Executing NPathComplexity-Analyzer: ........................................... 869 Executing Coupling-Analyzer: ........................................................... 1193 Executing NodeCount-Analyzer: ................................. 677 Executing Dependency-Analyzer: ................................... 703 Executing Hierarchy-Analyzer: ........................................... 880 Executing Inheritance-Analyzer: ..................... 421 Executing CodeRank-Analyzer: ...... 126 Executing CyclomaticComplexity-Analyzer: ........................................... 869 Executing ClassLevel-Analyzer: ....................................... 783 Executing NodeLoc-Analyzer: ............................................... 951 Generating pdepend log files, this may take a moment.

This command has produced one xml-report named summary.xml that contains a summary of all metrics collected for the analyzed php source code.

And you will get two charts. The first one shows the inter package dependencies, similar to those charts generated by JDepend and the second one shows a visual summary of the analyzed project source code.
