Macros for Automatic Global Variable Creation
In addition to the macros discussed earlier, a few macros allow easy creation of simple global variables. These are nice to know in case you want to introduce global flags, for example. This is somewhat bad practice, but Table 9.12 describes macros that do exactly this task. They don't need any zval allocation; you simply have to supply a variable name and value.
Obrßzek 33-9. Table 9.12. Macros for Global Variable Creation
Note: All macros in Table 9.12 create a global variable of the name "name" with the value "value". |
| Macro | Description |
| SET_VAR_STRING(name, value) | Creates a new string. |
| SET_VAR_STRINGL(name, value, length) | Creates a new string of the specified length. This macro is faster than SET_VAR_STRING and also binary-safe. |
| SET_VAR_LONG(name, value) | Creates a new long. |
| SET_VAR_DOUBLE(name, value) | Creates a new double. |
