Additional API Macros
Shortly before the release of this book, a new set of macros was introduced into
Zend’s API that simplify access to zval containers (see Table 9.19). However, we chose
not to use them in the example sources, as they don’t make many accesses to zval
containers, and the macros would have resulted in source code that was more difficult
to read.

Macro Refers to
Z_LVAL(zval) (zval).value.lval
