According to This post on the ThinkPHP Blog today, they're looking for any and all developers out there that are working with SAP in their business and want to bridge the connection between it and PHP.
Please tell me about your needs and if you successfully could access SAP and which kind of connection (SAP XI, saprfc etc.) you used. I'll post a summary of those experiences later.
In the meantime, checkout the blog "PHP: A new twist to SAP development" (not much content there yet, but I hope it will grow in the future). It's the weblog of Craig Cmehil, a SAP employee who's the author of the book "The SAP developer's guide to PHP".
You don't seen much on this kind of connection, but there has to be a need for it in companies out there (espeically with the widespread usage of SAP).
