如何使用PHP获取两个日期之间的明智日期？

I have two dates of the form:

Start Date: 2016-09-01 
End Date: 2016-09-30

Now I need to get dates week wise between these two in the following form:

2016-09-01 2016-09-03 (partial week)
2016-09-04 2016-09-10 (full week)
2016-09-11 2016-09-17 (full week)
2016-09-18 2016-09-24 (full week)
2016-09-25 2016-09-30 (partial week)

How can I do this in PHP?
