Php 如何在日期范围之间动态添加天数间隔

我想打印间隔内给定日期范围内的所有日期。但如果有周六，我会增加2天，如果有周日，我会增加1天

对于ex-

1） 2018年7月30日是我的开始日期。再加上5天

2） 2018年8月6日是第二个日期，比2018年8月6日增加5天，因此可能是2018年8月11日，但2018年8月11日和2008年12月12日是周六和周日，因此增加两天，下一个日期将是

3） 2018年8月13日是我的第三次约会。。。2018年8月13日+5天=2018年8月18日，但2018年8月18日和2018年8月19日是周六和周日，因此再增加2天

4） 2018年8月20日是我的第四次约会……就像怀斯一样

5） 2018年8月27日是我的最后一天，因为这是我的结束日期

6） 完成

如果有一些非标准的要求，我宁愿放弃使用

，而使用

循环。大概是这样的：
