PMD Lite  

The Lite   version of the course, approximately 60 hours of instruction, provides a select portion of the curriculum for those who don't require the full menu of topics. PMD Lite runs concurrently with the full version of the course and is offered at a reduced price.

PMD Lite    focuses on the core module development aspects of the class, skipping topics such as developer tools, events, custom Drush commands, and caching.

Cost: $2,500

Excellent course - cannot recommend highly enough! Covers all the necessary topics in great detail. 

  • Ian Finlay, Summer 2022

PMD not only provides the how to, but also always strives to answer the why.

  • Why are coding standards important?
  • Why should I use PhpStan?
  • Why do I care about dependency injection?
  • Why is Xdebug better than other debugging tools?
  • Why should I take the time to write automated tests?
  • Why do I need to pay attention to caching?
  • Why does it matter which IDE I use?

Many PMD lessons start by making the case for why the topic about to be taught will save you time, make you more efficient, or allow your code to be more flexible - real motivation for you and your fellow classmates to fully embrace the topics.
