After some debugging it now works. Ready for beta testing.
After more than a decade of neglected support now PHP and SAP connector is up to scratch.
2001 I started on an alpha/beta PHP 4 release and Koucky's SAPRFC SAP connector. My code has remained remarkably intact.
the problems I had:
going from patch level 1 to 18. level 1 used direct ip addresses, level 18 domain addresses, to my surprise my server did not have contact with the company DNS. It took me quit a while to figure this out. My PHP code for the SAP prereqs (see below) were a bit 'rough'.
A workflow grabbing an SAP table, with a SAP prereq (verifying a SAP job is run ok). Used as my test case.
