$next_mont_first_date = date('Y-m-20 00:00:00',strtotime('next month'))

2個日期比較大小的方法

protected function DateCompare($dateString1,$dateString2){

$month1 = date("m", strtotime($dateString1));

$month2 = date("m", strtotime($dateString2));

$day1 = date("d", strtotime($dateString1));

$day2 = date("d", strtotime($dateString2));

$year1 = date("Y", strtotime($dateString1));

$year2 = date("Y", strtotime($dateString2));

$hour1 = date("H", strtotime($dateString1));

$hour2 = date("H", strtotime($dateString2));

$minute1 = date("i", strtotime($dateString1));

$minute2 = date("i", strtotime($dateString2));

$second1 = date("s", strtotime($dateString1));

$second2 = date("s", strtotime($dateString2));

$do1 = mktime($hour1, $minute1, $second1, $month1, $day1, $year1);

$do2 = mktime($hour2, $minute2, $second2, $month2, $day2, $year2);

if($do1

return '0';

}

if($do1==$do2){

return '1';

}

if($do1>$do2){

return '2';

}

}
