二维数组排序这个要怎么做？
Array
(
[0] => Array
(
[userid] => 123707
[username] => qycntest
[realname] => 企业开发
[sex] => 3
[departname] =>
)
[1] => Array
(
[userid] => 123725
[username] => devtest-23
[realname] => nn
[sex] => 1
[departname] => 17c
[creator] => 1
)
[2] => Array
(
[userid] => 123726
[username] => devtest-24
[realname] => oo
[sex] => 1
[departname] => 测试部
[isManager] => 1
)
[3] => Array
(
[userid] => 123728
[username] => devtest-26
[realname] => qq
[sex] => 1
[departname] => 测试部
[isManager] => 1
)
[4] => Array
(
[userid] => 123732
[username] => devtest-30
[realname] => uu
[sex] => 1
[departname] => 测试部
)
)
我要把有isCreator的项的排在最前面，其次是isManager=1排在后面，最后就是普通用户，请教下大家！ 谢谢
