var_dump(array_reduce($input, fn($fusion, $value) => $carry * $value, 1));

Resulted in this output:

/php-src/Zend/zend_API.c:498: _Bool zend_null_arg_deprecated(const char *, uint32_t): Assertion `arg_num > 0' failed.
Aborted (core dumped)

so not familiar with gmp but when trying to convert to GMP number representation it falls back to default case when attempting to convert to a zend_long but we re dealing with a NULL here (as 1st argument). representing it by 0 and returning success
or raising an exception work for me.
