PHP;">
$month_date = '2015-09-25';
$start_time = strtotime($month_date);
$start_week = date('w',$start_time);

$weeks_in_month = ceil(($start_week+$total_month_day)/7);
$month_day_arr = [];
$start_month_day = 1;
for($i=0;$i<$weeks_in_month;$i++) {
for($j=0;$j<7;$j++){
if($i ==0 && $j >= $start_week) {
$month_day_arr[$i][$j] = $start_month_day;
$start_month_day++;
} elseif($i == 0) {
$month_day_arr[$i][$j] = '';
} else {
$month_day_arr[$i][$j] = $start_month_day;
$start_month_day++;
}
if($start_month_day > $total_month_day){
break;
