How to custom your own validate method 加入定制自己的验证方法
==================================================

[](#how-to-custom-your-own-validate-method-加入定制自己的验证方法)

- Just extends Validator class and add your own method (继承)
- Or Just write global function (写全局函数) *notes:*method|function should be like isXxx($value) or isXxx($value, $params), example:
    方法或函数格式必须是这样的，参考以下：

```
function isZero($value)
{
    return $value === 0;
}

function isHasstr($value, $param)
{
    return strpos($value, $param) !== false;
}
```
