The problem is that you’re using 'M'
and 'D'
, which are a textual representations, MySQL is expecting a numeric representation of the format 2010-02-06 19:30:13
Try: date('Y-m-d H:i:s')
which uses the numeric equivalents.
edit: switched G
to H
, though it may not have impact, you probably want to use 24-hour format with leading 0s.
