核心验证器(Core Validators)

Yii提供了一系列常用的核心验证器，主要存在于 yii\validators 命名空间之下。为了避免使用冗长的类名，可以直接用昵称来指定相应的核心验证器。比如可以用 'required' 昵称代指 yii\validators\RequiredValidator 类，比如：

<span style="color: #008080;">1</span> <span style="color: #0000ff;">public</span> <span style="color: #0000ff;">function</span><span style="color: #000000;"> rules()
</span><span style="color: #008080;">2</span> <span style="color: #000000;">{
</span><span style="color: #008080;">3</span>     <span style="color: #0000ff;">return</span><span style="color: #000000;"> [
</span><span style="color: #008080;">4</span>         [['email', 'password'], 'required'],
<span style="color: #008080;">5</span> <span style="color: #000000;">    ];
</span><span style="color: #008080;">6</span> }

yii\validators\Validator::builtInValidators 属性声明了所有被支持的验证器昵称。
