What is PDC? • Packfire Dependency Checker • Minimal CLI tool written in PHP • Class dependency problems in PHP • Generates a little report 1 Dec 2012 Sam-Mauris Yong 2 

Checks for… • Unused use statement; • Missing declaration of a class being used; • Namespace that doesn't exist according to PSR-0; • Files without namespace declaration. 1 Dec 2012 Sam-Mauris Yong 3 

Why PDC? • Classes are loaded real-time with autoloaders. • Misspelled namespaces or classnames undetected. • Difficult to check until execution • IDEs do not report such errors. 1 Dec 2012 Sam-Mauris Yong 4
