[development] Bridging PHP to Java or C++?

If you know Weka, then the best thing (IMO) is to use web services, rather than doing some php to java native integration. 
It is less esoteric.

check out triana http://www.trianacode.org (it uses weka inside, I
think) 
and maybe http://grid.deis.unical.it/weka4ws/ 

Another option would be to do a simple restful wrapping of weka code via
servlets.

If you are into python, orange ( http://www.ailab.si/orange ) is a very
good thing. That + twisted can be a killer web datamining services
environment.

C++, as pecl extensions.

You can always submit them to php.net
