i wish to rewrite a mysql query which use month() and year() functions to display all the post from certain month which goes to my function as a 'Y-m-d' parameter format, but I don't know how can I get the last day of the given month date.
$query_date = '2010-02-04';
list($y, $m, $d) = explode('-', $query_date);
$first_day = $y . '-' . $m . '-01';
