构造函数初始化私有属性，
public function isValid($value)
{
if (!is_string($value) && !is_int($value) && !is_float($value)) {
$this->_error(self::INVALID);
return false;
}
$this->_setValue($value);

if (false === $status) {
$this->_error(self::ERROROUS);
return false;
}
if (!$status) {
$this->_error(self::NOT_MATCH);
return false;
}
return true;
}
进行验证工作。
自定义校验器编写
继承Zend_Validate_Interface接口实现用户自定义校验器。
代码案例，功能判断指定数值是否为3的倍数。
