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); 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。
