本文给大家汇总了3个php获取日历的函数，分别是php获取指定日期的月份的日历、获取指定日期所在月的开始日期与结束日期、获取当前星期的日期范围，都是比较常用
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= $start_week) {$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 > $total_month_day){break;} }}echo
;print_r($month_day_arr);array( [0] => array([0] =>[1] =>[2] => 1[3] => 2[4] => 3[5] => 4[6] => 5)[1] => array([0] => 6[1] => 7[2] => 8[3] => 9[4] => 10[5] => 11[6] => 12)[2] => array([0] => 13[1] => 14[2] => 15[3] => 16[4] => 17[5] => 18[6] => 19)[3] => array([0] => 20[1] => 21[2] => 22[3] => 23[4] => 24[5] => 25[6] => 26)[4] => array([0] => 27[1] => 28[2] => 29[3] => 30))     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 );if ( $returnfirstday ) {$monthfirstday = date( 'y-m-1 00:00:00', $timestamp );return $monthfirstday;} else {$mdays = date( 't', $timestamp );$monthlastday = date( 'y-m-' . $mdays . ' 23:59:59', $timestamp );return $monthlastday;} }
获取当前星期的日期范围，也就是从星期一到星期日的日期范围。
function getweekrange($date){$ret=array();$timestamp=strtotime($date);$w=strftime('%u',$timestamp);$ret['sdate']=date('y-m-d 00:00:00',$timestamp-($w-1)*86400);$ret['edate']=date('y-m-d 23:59:59',$timestamp+(7-$w)*86400);return $ret;}//author:zhxia 获取指定日期所在月的开始日期与结束日期function getmonthrange($date){$ret=array();$timestamp=strtotime($date);$mdays=date('t',$timestamp);$ret['sdate']=date('y-m-1 00:00:00',$timestamp);$ret['edate']=date('y-m-'.$mdays.' 23:59:59',$timestamp);return $ret;}//author:zhxia 以上两个函数的应用function getfilter($n){$ret=array();switch($n){case 1:// 昨天$ret['sdate']=date('y-m-d 00:00:00',strtotime('-1 day'));$ret['edate']=date('y-m-d 23:59:59',strtotime('-1 day'));break;case 2://本星期$ret=getweekrange(date('y-m-d'));break;case 3://上一个星期$strdate=date('y-m-d',strtotime('-1 week'));$ret=getweekrange($strdate);break;case 4: //上上星期$strdate=date('y-m-d',strtotime('-2 week'));$ret=getweekrange($strdate);break;case 5: //本月$ret=getmonthrange(date('y-m-d'));break;case 6://上月$strdate=date('y-m-d',strtotime('-1 month'));$ret=getmonthrange($strdate);break;}return $ret;}
