I discovered that if I comment out "ZEND_ARG_TYPE_INFO(0, port, IS_LONG, 1)", it works, but I'd like to type hint that second optional argument if possible. Maybe I was always doing this the wrong way, but I thought that the last argument 1 to allow null was the proper way to handle this and I'm not sure why it results in an error now. Can anyone tell me the correct way to approach this in PHP 8? Thank you!Your arginfo declares the arugment as nullable, but your zpp call does not. Thus the error. You need: zend_bool port_is_null = 1; zend_parse_parameters_throw( ZEND_NUM_ARGS(), "s|l!", // ! means nullable &hostname, &hostnameLength, &port, &port_is_null // Whether null was actually passed );
I tried that, but I still get the "Arginfo / zpp mismatch during call" error.
