使用的版本是

"topthink/think-validate": "^2.0"

class MemberValidate extends Validate
{
    protected $rule =   [
        'name'  => 'require|length:3,25',
        'password' => 'require|length:8,16',
        'email' => 'require|email'
    ];

    protected $message  =   [
        'name.require' => '名稱不能為空',
        'name.length'     => '名稱長度在3-25個字符',
        'password.require'   => '密碼不能為空',
        'password.length'  => '密碼長度在8-16個字符',
        'email'        => '請輸入有效的郵箱地址'
    ];

    protected $scene = [
        'register'  =>  ['name','password','email'],
        'login'  =>  ['password','email']
    ];

}

$validate  =  new MemberValidate();
//$rs  = $validate->check($data); //這樣是正常的，下面加場景驗證就報錯。
$rs  = $validate->scene('login')->check($data);

報錯信息如下：

filter_var(): Argument #3 ($options) must be of type array|int, null given
