That depends largely on the situation. For instance, if you want to
increment a date in a MySQL table, you would likely do it with a MySQL
statement, because to do it in PHP, you need to do a read, then add the day,
then a write, (two DB calls). With MySQL, you would just do something like:
update `mytable` set 'columnname` date_add(columnname, interval 1 day);
One call to the DB instead of two, much more efficient.
There are many instances where you would want to use PHP to manipulate dates
too, depending on their circumstances.
