$next_mont_first_date = date('Y-m-20 00:00:00',strtotime('next month'))
2个日期比较大小的方法
protected function DateCompare($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<$do2){
return '0';
}
if($do1==$do2){
return '1';
}
if($do1>$do2){
return '2';
}
}
