我有这个多维数组：

(
[0] => Array
(
[0] => 2012-02-26 07:15:00
)
[1] => Array
(
[0] => 2012-02-26 17:45:00
[1] => 2012-02-26 18:55:00
)
[2] => Array
(
[0] => 2012-02-26 18:55:00
[1] => 2012-02-26 17:45:00
)
[3] => Array
(
[0] => 2012-02-26 18:57:00
[1] => 2012-02-26 17:45:00
[2] => 2012-02-26 18:55:00
)
当我计运算符阵列时,我得到1,2,3.我怎么能在3,1中收到它？我需要得到最后3个具有最高子阵列数的子阵列(DESC,它意味着3,2).我怎样才能做到这一点？
