Years ago I wrote the first book on SAP and PHP technologies together, it was published by SAP PRESS and was more of a success than we originally thought it would be. Now 8 years later I decided to take the content and republished a 2nd edition.
The book came about based on my entering into the SAP environment and all the blogs I wrote about that journey.
The new book is available in print, Kindle and iBook format and usually you can ask any questions you like here or .
The updated version of the book includes new information about the RFC connectors as well as a section on SAP HANA.
