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 > $total_month_day){ break; } } } echo "<pre class="brush:php;toolbar:false">"; print_r($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; }
