Let's say I've allocated a zval as follows

 

zval *zv;
MAKE_STD_ZVAL(zv);

 

If I want to free this zval properly, how should I do it?  Is it enough to call zval_dtor()?  FREE_ZVAL()?  I have seen some extensions that call BOTH of these.

 

Second question:  If zv is an array, do I need to do something special to ensure that the array elements are also freed?
