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,都是比较常用的方法,有需要的小伙伴可以参考下。

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] = &#39;&#39;;
    } 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( &#39;Y-m-1 00:00:00&#39;, $timestamp );
      return $monthFirstDay;
    } else {
      $mdays = date( &#39;t&#39;, $timestamp );
      $monthLastDay = date( &#39;Y-m-&#39; . $mdays . &#39; 23:59:59&#39;, $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);
  $w=strftime(&#39;%u&#39;,$timestamp);
  $ret[&#39;sdate&#39;]=date(&#39;Y-m-d 00:00:00&#39;,$timestamp-($w-1)*86400);
  $ret[&#39;edate&#39;]=date(&#39;Y-m-d 23:59:59&#39;,$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);
  $mdays=date(&#39;t&#39;,$timestamp);
  $ret[&#39;sdate&#39;]=date(&#39;Y-m-1 00:00:00&#39;,$timestamp);
  $ret[&#39;edate&#39;]=date(&#39;Y-m-&#39;.$mdays.&#39; 23:59:59&#39;,$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[&#39;sdate&#39;]=date(&#39;Y-m-d 00:00:00&#39;,strtotime(&#39;-1 day&#39;));
  $ret[&#39;edate&#39;]=date(&#39;Y-m-d 23:59:59&#39;,strtotime(&#39;-1 day&#39;));
  break;
  case 2://本星期
  $ret=getWeekRange(date(&#39;Y-m-d&#39;));
  break;
  case 3://上一个星期
  $strDate=date(&#39;Y-m-d&#39;,strtotime(&#39;-1 week&#39;));
  $ret=getWeekRange($strDate);
  break;
  case 4: //上上星期
  $strDate=date(&#39;Y-m-d&#39;,strtotime(&#39;-2 week&#39;));
  $ret=getWeekRange($strDate);
  break;
  case 5: //本月
  $ret=getMonthRange(date(&#39;Y-m-d&#39;));
  break;
  case 6://上月
  $strDate=date(&#39;Y-m-d&#39;,strtotime(&#39;-1 month&#39;));
  $ret=getMonthRange($strDate);
  break;
  }
  return $ret;
  }
