我有问题。我有一个多维数组,看起来像这样:
Array ( [0] =>
Array (
[0] => Testguy2's post.
[1] => testguy2
[2] => 2013-04-03
)
[1] => Array (
[0] => Testguy's post.
[1] => testguy
[2] => 2013-04-07
)
);
我想从最新日期到最旧日期对帖子进行排序,所以它看起来像这样:
Array ( [1] => Array (
[0] => Testguy's post.
[1] => testguy
[2] => 2013-04-07
)
[0] => Array (
[0] => Testguy2's post.
[1] => testguy2
[2] => 2013-04-03
)
);
我该如何排序?
