如何使用PHP获取每个月的第一天数组值

日期数据返回我的数组。我想每个月日期一个数组集

Array
(
    [2014/09/01 13:47:54] => 73206
    [2014/09/02 11:00:01] => 73205
    [2014/10/01 14:00:07] => 73206
    [2014/10/03 15:00:01] => 73207
    [2014/11/01 18:00:02] => 73208
    [2014/11/05 02:00:01] => 73209
    [2014/12/01 10:00:01] => 73210
    [2014/12/02 12:00:02] => 73209
    [2014/12/04 13:00:02] => 73208
    [2014/01/01 23:00:02] => 73209
    [2014/01/08 09:00:02] => 73210
    [2014/02/01 10:00:03] => 73211
    [2014/02/19 11:00:02] => 73210
)

我的期望是这样的

[2014/09/01 13:47:54] => 73206
[2014/10/01 14:00:07] => 73206
[2014/11/01 18:00:02] => 73208
[2014/12/01 10:00:01] => 73210
[2014/01/01 23:00:02] => 73209
[2014/02/01 10:00:03] => 73211
