Why would it grow from 2 to 3 after the call to $obj->do_somtehing? Why does the reference count of the object drop from 2 to 1 after the function is called? If I remove the line $obj->do_something I get the following. object(test)(1) refcount(2){ ["dummy"]=> long(1) refcount(2) } object(test)(1) refcount(2){ ["dummy"]=> long(1) refcount(2) } Perhaps I am missing something obvious? > > >This will produce the following output: > > > >object(test)(1) refcount(2){ > > ["dummy"]=> > > long(1) refcount(2) > >} > >Hello > >object(test)(1) refcount(1){ > > ["dummy"]=> > > long(1) refcount(3) > >} > > > >ZEND_SEND_VAR is the opcode that does this in this scenario as well > > > > > > > > > >-jason > > > > > > > >-- > >Jason T.
