Hi all,
For my Machine Learning toolkit, I'm looking to draw on the work of either the Java Weka ML system or the MLC++ library.
Trying to integrate either Java or a C++ library into PHP just so that one can run a Java or C++ machine learning system sounds really painful. Unless the performance needs to be high and the transaction latency extremely low, this sounds like a perfect case for NOT integrating the code, but calling it via some sort of remote procedure call (RPC) or remote method instantiation (RMI -- Javaspeak for a previously existing concept -- grrrr >:-( ). How about writing a Java server that does the machine language stuff that can accept an XML-RPC socket connection from Drupal instead? That's got to be a thousand times easier to do, and the performance won't be that bad. I've already done this kind of thing twice. In one instance I open a socket to a Java server to do "real time" transactions with it from a Drupal module, and in another, I make a SOAP connection to a C++ server from a Drupal module, likewise to do "real time" transactions. I would not even have a prototype working if I tried to write a PHP extension that tried to run the Java or C++ application natively. ..chrisxj
