[PHP-DEV] UdmSearch extension From: Alexander Barkov (bar <email protected>)
Date: 10/12/00

  Hello!

I'm learning a possibility to add UdmSearch extension into PHP.

Please find udmsearch.c in attach. This program demonstrates
typical UdmSearch session.

Could anybody give a suggestions on how to make PHP interface.
It is almost clean for me how to implement stages 0,1,2,4, and 6.

I need interface tips for stages 3 and 5 where one need to have a deal
with structures members.

Any ideas?

Thanks!

P.S.
  It would be also great if somebody can give general plan
on how to implement this all.

P.P.S.
  BTW. Where I can find Rasmus?
