Probably :)
That syntax looks rather like PHP5 to me. I'd say this: 1) don't pass
everything by reference -- it actually is slower to do so in the PHP
engine from everything I've read. 2) objects are automagically passed
by reference in PHP5. You don't have to do anything at all to get that
behaviour. 3) Smarty's code has not changed to reflect this change in
PHP5. If you really want to assign an object to smarty as by-val then
you must use the clone the object as you assign it. In other words, if
all you want to have is your objects passed by reference then leave
your original code the way it was. You are already getting that
behaviour in PHP5.
Of course, if you are using PHP4, that's a different matter entirely...

Errr... ok. So I don't need assign_by_ref() at all? Then why does it say
I need it to get objects passed to Smarty here?
http://smarty.php.net/manual/en/advanced.features.php
--> Outdated documentation? That's bad...
Anyways, thanks for the info, I'll see if just using normal assign() works.
