A set of macros was introduced into Zend's API that simplify access to zval
containers (see Table 46-19).
Table 46-19. API Macros for Accessing zval Containers
| Macro | Refers to |
| Z_LVAL(zval) | (zval).value.lval |
| Z_DVAL(zval) | (zval).value.dval |
| Z_STRVAL(zval) | (zval).value.str.val |
| Z_STRLEN(zval) | (zval).value.str.len |
| Z_ARRVAL(zval) | (zval).value.ht |
| Z_LVAL_P(zval) | (*zval).value.lval |
| Z_DVAL_P(zval) | (*zval).value.dval |
| Z_STRVAL_P(zval_p) | (*zval).value.str.val |
| Z_STRLEN_P(zval_p) | (*zval).value.str.len |
| Z_ARRVAL_P(zval_p) | (*zval).value.ht |
| Z_LVAL_PP(zval_pp) | (**zval).value.lval |
| Z_DVAL_PP(zval_pp) | (**zval).value.dval |
| Z_STRVAL_PP(zval_pp) | (**zval).value.str.val |
| Z_STRLEN_PP(zval_pp) | (**zval).value.str.len |
| Z_ARRVAL_PP(zval_pp) | (**zval).value.ht |
