$Array = new java_class("java.lang.reflect.Array");
for($i=0; $i<$Array->getLength($nameValues); $i++)
   echo $nameValues[i] . "\n";

should work if you have PHP5 (please see
tests.php5/arrayInterface.php).  In PHP4 the bridge uses the same method
as the ext/java: it copies all elements from the java array into a PHP
hashtable $nameValues.  I don't know at the moment how it is possible to
ask a PHP hash table for its length.

The bridge accesses java via reflection.  For some reasons Sun decided
to wrap arrays differently (via a separate java.lang.reflect.Array
interface).

This should work in both PHP4 and PHP5, please see
tests.php5/iteratorInterface.php. The example uses a Map, but
getPhpMap() works for Arrays, Maps and Collections. 

Can you please set the log level to debug and send the result? I am
looking for the output of: logDebug("returning map for "+
value.getClass());

Not necessary.  I think that for some reason the value is neither an
Array, nor a Map or Collection.  We'll see.
