How do you decide not to use the correct wording?

Here is my test case:

class TestModel extends \yii\base\Model{    public $password;    public function rules()    {        return [            ['password', 'checkPassword']        ];    }    public function checkPassword($attribute, $params)    {        if (!ctype_alnum($this->$attribute)) {            $this->addError($attribute, 'password error');        }    }}

Test CASE1:

$model = new TestModel();$model->password = '1121312&&UJ9123/.';$model->validate();var_dump($model->getErrors()); //会打印出有错误

Test Case 2:

$model = new TestModel();$model->password = '1121312';$model->validate();var_dump($model->getErrors()); //无错误
