Answer 1

Yep, that appears to be the case...

To get around that you could use...

echo date("F",strtotime("first day of -8 Month"));

That's from some discussion on http://php.net/manual/en/function.strtotime.php

Answer 2

This is happening because February has 28 or 29 days. Use this hack and you will get the correct date

echo date("F",strtotime("first day of -8 Month"));

Answer 3

感谢您的回答-我设法使用以下方法解决了该问题：

strtotime(date('Y-m')." -8 Month")
