Hi!
I just finished a patch to use the mersenne twister in php3. Basically I
modified the rand.c functions with the code from Cokus.
There are some design decisions I took while adapting the code from Cokus
implementation to PHP3. Basically they have to do with the fact that
integers in php3 are 2^31 at most and cokus randomMT returns 2^32.
there is also a possibility to improve the performance in 64bit
architectures but I dont know which defines to use to change that.
I also mailed Cokus to ask permission to use his code and I got a positive
response.
Right now, the code is in a fase "It works for me". I tested the results
against the original function and they are the same, so the patch seems to
be good.
See ya!
