分享3个php获取日历的函数
提供一个日期,获取这个日期的星期对应日历列表,键为星期标示
$month_date = '2015-09-25';
$start_time = strtotime($month_date);
$start_week = date('w', $start_time);
$total_month_day = date('t', $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 > $total_month_day){
break;
}
}
}
echo "<pre>";
print_r($month_day_arr);

获取指定日期所在月的开始日期与结束日期
/**
* @param string $date
* @param boolean 为true返回开始日期，否则返回结束日期
* @return array
* @access private
*/
private function getMonthRange( $date, $returnFirstDay = true ) {
$timestamp = strtotime( $date );

获取当前星期的日期范围，也就是从星期一到星期日的日期范围。
function getWeekRange($date){

return $ret;
}
