为什么当前日期显示从PHP当前日期的下一个日期？

I want to get current date in php but it is displaying one day advance.

I am surprised why this is happening as I am using very simple code:

date('Y-m-d')

Please set date time zone as IST. Then try. May your server config time zone is USA. So please add below lines in your code and check it

date_default_timezone_set('Asia/Kolkata');
echo date('d-m-Y');

Try to put this function date_default_timezone_set("Asia/Bangkok")
