Let's say we have a custom PHP extension like:
PHP_RSHUTDOWN_FUNCTION(myextension)
{
// How do I call myfunction() from here?
return SUCCESS;
}
PHP_FUNCTION(myfunction)
{
// Do something here
...
RETURN_NULL;
}
How can I call myfunction() from the RSHUTDOWN handler?
Using the provided macros the call will be:
PHP_RSHUTDOWN_FUNCTION(myextension)
{
ZEND_FN(myFunction)(0, NULL, NULL, NULL, 0 TSRMLS_CC);
return SUCCESS;
}
When you're defining you function as PHP_FUNCTION(myFunction) the preprocessor will expand you're definition to:
ZEND_FN(myFunction)(INTERNAL_FUNCTION_PARAMETERS)
which in turn is:
zif_myFunction(int ht, zval *return_value, zval **return_value_ptr, zval *this_ptr, int return_value_used TSRMLS_DC)
The macros from zend.h and php.h:
#define PHP_FUNCTION ZEND_FUNCTION
#define ZEND_FUNCTION(name) ZEND_NAMED_FUNCTION(ZEND_FN(name))
#define ZEND_FN(name) zif_##name
#define ZEND_NAMED_FUNCTION(name) void name(INTERNAL_FUNCTION_PARAMETERS)
#define INTERNAL_FUNCTION_PARAMETERS int ht, zval *return_value, zval **return_value_ptr, zval *this_ptr, int return_value_used TSRMLS_DC
#define INTERNAL_FUNCTION_PARAM_PASSTHRU ht, return_value, return_value_ptr, this_ptr, return_value_used TSRMLS_CC
Why dont you make the PHP_FUNCTION a stub like so:
void doStuff()
{
// Do something here
...
}
PHP_RSHUTDOWN_FUNCTION(myextension)
{
doStuff();
return SUCCESS;
}
PHP_FUNCTION(myfunction)
{
doStuff();
RETURN_NULL;
}
