In my Worpdress site I am using the function current time to return the current date in MySQL timestamp data type format.
My goal is to perfom some operations on the result (like substracting 1 day). I found on the web date_sub but the requirement is that its parameter should be a DateTime type.
Warning: date_sub() expects parameter 1 to be DateTime, string given in C:\xampp\htdocs\blog\wp-content\themes\twentyten\header.php on line 107
How can I perform substraction on the MySQL timestamp data type format, or is there a Worpdress function that returns current date in DataTime format?
You help is always appreciated.

date_sub ，但要求是它的参数应该是 DateTime 类型。
DataTime 格式返回当前日期的Worpdress函数？
Something like this should work:
微信扫一扫$date = new DateTime();
$date->sub(new DateInterval("P1D"));
echo $date->format("Y-m-d H:i:s");
If you aren't familiar with it, you should look at PHP SPL Date/Time classes. They are immensely useful and make this type of thing very easy.
