Hi
I have a few questions about zend_fcall_info and zend_fcall_info_cache.
Regarding zend_fcall_info
What is function_name useful for? I have a feeling it's for error
reporting, but I'm not sure
What is symbol_table for? Maybe to put in the function's context other
variables beside the parameters, like $this?
What is zend_fcall_info_cache for? I've seen in some places that
zend_call_function() sometimes takes a NULL for it. When is it useful to
cache information about the function call?
Regards,
Flavius
