hmm, what does unwrap mean? I'll have a look at the EJB rmi(iiop example...

Yes, just switched to cvs/1.0.8 yesterday, haven't looked into those 
examples yet.

see above, but the link should generally be working.

Thanks.  You're right, iterating over non-primitive
values of arrays wasn't possible until now.  I have
just checked a fix into the CVS head.  I am going to
test and release 1.0.8 asap, hopefully this weekend.

Until then please use PHP 5 and PHP/Java Bridge 1.0.7
with the following patch applied (see below).

Thank you for reporting this bug.
