### CaptchaAbstract 为生成验证码的抽象类，必须实现三个抽象方法

[](#captchaabstract-为生成验证码的抽象类必须实现三个抽象方法)

```
    /**
     * 存储验证码
     * @param  string $key [存储使用的键]
     * @param  string $text [验证码]
     * @return [bool]
     */
    protected abstract  function storeText(string $key,string $text);

    /**
     * 获取存储的字符串
     * @param  string $key [存储使用的键]
     * @return [string]    存储的验证码
     */
    protected abstract  function getStoreText(string $key);

    /**
     * 删除存储的字符串
     * @param  string $key [存储使用的键]
     * @return [bool]
     */
    protected abstract function deleteStoreText(string $key);

```

```
$res->create('sjfdh'); //生成验证码图像 ,
$res->create('./file/img.png'); //将生成的验证码存储在某个文件内，只支持保存为png；
$res->verify('sdfkj','key'); //验证码验证，不区分大小写，存储使用的键为key
$res->verify('sjdfjk','key',true); //验证码验证，区分大小写，存储使用的键为key

```

### 其他设置请自行查看抽象类方法
