This behaviour can be changed by enabling the php.ini flag `v8js.use_array_access`. If set, objects of PHP classes that implement the aforementioned interfaces are converted to JavaScript Array-like objects. This is by-index access of this object results in immediate calls to the `offsetGet` or `offsetSet` PHP methods (effectively this is live-binding of JavaScript against the PHP object). Such an Array-esque object also supports calling every attached public method of the PHP object + methods of JavaScript's native Array.prototype methods (as long as they are not overloaded by PHP methods).

V8Js versions 0.2.4 and before did not stop JS code execution on PHP exceptions,
but silently ignored them (even so succeeding PHP calls from within the same piece
of JS code were not executed by the PHP engine). This behaviour is considered as
a bug and hence was fixed with 0.2.5 release. Nevertheless there is a
compatibility php.ini switch (`v8js.compat_php_exceptions`) which turns previous
behaviour back on.
