Looking through the source, there are a few extensions which create objects
internally and when they do this (usually with an instanciate method), they
typically set is_ref == 1. Like so:

 

object_init_ex(object, class_entry);

object->refcount = 1;

object->is_ref = 1;

 

 

Why set the is_ref? Aren't objects treated as is_ref natively throughout the
engine? Or is this just old code from PHP 4 days that is still hanging
around?

 

Thanks for the understanding.

Hello Bob,

  in php 4 that prevents a useless copy after new (and dont't ask why).
Since your stuff is php 5 only you should make that is_ref=0.
