PHP Fatal error: Variadic parameter cannot have a default value

[keksa]

When creating a mock of the following class, phony will crash with Variadic parameter cannot have a default value. The problem is with the ?int ...$statuses definition, without ? there is no crash.

class being mocked

class Foo {
    /**
     * @var int|null
     */
    private $status;

    public function hasStatus(?int ...$statuses): bool
    {
        return in_array($this->status, $statuses, true);
    }
}

phony-generated source of mock

public function hasStatus(
    int ...$a0 = null
) : bool {
    $argumentCount = \func_num_args();
    $arguments = [];


    for ($i = 0; $i < $argumentCount; ++$i) {
        $arguments[] = $a0[$i - 0];
    }

    if (!$this->_handle) {
        $result = parent::hasStatus(...$arguments);

        return $result;
    }

    $result = $this->_handle->spy(__FUNCTION__)->invokeWith(
        new \Eloquent\Phony\Call\Arguments($arguments)
    );

    return $result;
}

Thanks for the report, I'll look into it. Which version of PHP are you running, out of interest?
