php生成日历

岸边露伴一动不动
最近工作中用到的一个并没有卵用的功能，根据开始日期和结束日期，生成日历数组
php的部分如下
function build_calendar($start,$end) {
$start_month = (Int)date('m',strtotime($start));
$start_year = (Int)date('Y',strtotime($start));
$end_year = (Int)date('Y',strtotime($end));
$end_month = (Int)date('m',strtotime($end));
if ( $start_month == 1 ) {
$month = 12;
$year = $start_year - 1;
}else{
$month = $start_month - 1;
$year = $start_year;
}
$results = [];
while ( !($year == $end_year && $month == $end_month) ) {
if ( $month == 12 ) {
$year++;
$month = 1;
}else{
$month++;
}
// 本月第一天的位置
$firstDayOfMonth = mktime(0,0,0,$month,1,$year);
// 获取本月天数
$numberDays = date('t',$firstDayOfMonth);
// 获取本月第一天
$dateComponents = getdate($firstDayOfMonth);
$dayOfWeek = $dateComponents['wday'];
// 初始化天数计数器，从1号开始
$n = 0;
$result = [];
$line = 0;
while ($n < $numberDays) {
// 7天一行，7天一到新增一行
if ($dayOfWeek == 7) {
$dayOfWeek = 0;
}
$result[$line][$dayOfWeek] = date('Y-m-d',strtotime('+ '.$n.'days',$firstDayOfMonth));
if ( $dayOfWeek == 6 ) {
$line++;
}
// 计数器
$n++;
$dayOfWeek++;
}
$showMonth = str_pad($month, 2, "0", STR_PAD_LEFT);
$results[$year.'-'.$showMonth] = $result;
}
return $results;
}
传入开始日期及结束日期，生成月历如下
