Getting Started with new module

Some months back I inquired about writing a BEA Tuxedo module for PHP. I got side-tracked for a while, but now I'd like to resume exploring this possibility. Primarily, because I'd like to use this module myself, but also feel it would be a natural match to an environment like PHP on a web server. First obvious question is is anyone working on a Tuxedo hook? If not, I'd like to volunteer. For those not familiar with Tuxedo, its a high-end transaction middleware Client/Server environment used in many larger corporate environments. Reference http://www.beasys.com/products/tuxedo/index.shtml for a good starting point. My thoughts are that PHP should have the ability to be a Tuxedo client, so it can call Tux services elsewhere in a Tux environment. These services can be located on the same machine, one other machine, numerous other machines, even mainframes. Ideally, all seemlessly called. It would call services in much the same way PHP calls a service from a database. I would only propose a web/PHP server be a client to Tuxedo. I can't imagine how a Tux server would even technically be incorporated into PHP. So, where to start??? I've looked through some of the code for other external modules. Sybase_ct for instance which is another environment I'm familiar with. Tuxedo has numerous API calls, but most of them aren't used for clients, so I don't think there would be many new functions. A basic Tux client can be written with as few as 6 API functions. It does require some similar connection concepts as databases, and also has its own memory allocation / free functions (tpalloc, tpfree). My personal resume includes 8+ years of UNIX, C, and database development mostly on Solaris, Linux, Sybase, and Informix. I feel I should be technically able to complete this type of project. I've read the apidoc.txt and apidoc-zend.txt files, but seems there are still some holes. Can anyone suggest the best way to get started? Much appreciated, Brian Foddy bfoddy@mn.mediaone.net
