Array

如上面 先在year倒序查询的情况下 再按term为2的先查询 为1的后查询 最好用thinkphp
应该查出来是这样的
Array

[id] => 2
[user_id] => 1
[year] => 2013-2014
[term] => 2
)
Array
(
[id] => 1
[user_id] => 1
[year] => 2013-2014
[term] => 1
)
Array
(
[id] => 3
[user_id] => 1
[year] => 2012-2013
[term] => 1
)
回复内容：

[id] => 1
[user_id] => 1
[year] => 2013-2014
[term] => 1

ORDER关键字是可以给多个字段的
ORDER BY `year` DESC, `term` DESC
