If you€re a web programmer new to Drupal, this book shows you which programming techniques you can use€"and which you should avoid€"when building custom web applications with this content management framework. Drupal has its own set of programming principles that require a different approach, and many programmers make mistakes when relying on skills they€ve used for other projects. The guidelines in this book help you through the transition by demonstrating which programming practices conform to the €œDrupal way,€ and which don€t.

If you€re familiar with PHP, you€ll quickly learn how to take advantage of the powerful Drupal API.
