Introduction

As a proof-of-concept, I implemented a prototype for our SAP PHP Framework with the Zend Framework as a basis.

System Requirements

The prototype makes use of the following software:

• Apache
• mod_rewrite
• PHP >= 5.1.4
• SAPRFC extension
• Unix: Non-Unicode SAP RFCSDK 6.20
• Win32: librfc32.dll (part of SAPGUI)
• Zend Framework 0.7.0
• PEAR packages
• Pager package
• Smarty template engine
