See also the set of zend_call_method_with_[0-4]_params macros in zend_interfaces.h. Those allow to cache the function pointer (or use the one provided via "f" option by zend_parse_parameters) and therefore saving repeated lookups. But general comment: Do you really want to call a user function? - This might be the case when using callbacks, typically when this question pops up the aim is to call some PHP provided function, then often there is a better C level API ... going via PHP function is cumbersome and "slow". johannes
