/**
* 用多组规则断言关联数组的值
*
* 每个关联数组的元素均对应一组验证规则,如果这组验证规则不存在,则当成此元素无须验证
* 只有当关联数组的所有元素都通过其对应的组验证规则时，assert_arr() 方法才会返回 true。
*
*
* 用法：
* assert_arr(
* array(
* 'name' => 'iamsese' ,
* 'age' => 26
* ),
* array(
* 'name' => array(
* array('not_empty', '用户名不能为空'),
* array('min_length', 5, '用户名不能少于 5 个字符'),
* array('max_length', 20, '用户名不能超过 20 个字符'),
* ) ,
*
* 'age' => array(
* array('not_null', '年龄不能为空'),
* array('is_int', '年龄必须是整数'),
* array('between',18,50,true,'年龄必须是[18,50]的整数'),
* ) ,
* ),
* $flds_failed
* );
*
* * 如果提供了 $flds_failed 参数，则验证失败的规则会存储在 $failed 参数中
*
* @param array $row 要验证的关联数组
* @param array $flds_rules 关联数组的键对应的多组规则
* @param mixed $flds_failed 保存验证失败的 字段->错误信息 的关联数组
* @param boolean $withFailedRule 是否保存验证失败的规则信息
*
* @return boolean 验证结果
