Question

所以我整天都在写这个页面来拉出存储在特定组的表中的会议，

丢弃任何超过4个月的会议，以及未来10个月的会议，所以它显示了一年的会议但从3个月前开始，所以你可以看到最近发生了什么，如果你想要除了什么是将要发生。

一切正常 - 除了天+/-日期接缝的比较非常直观我今天在27日进行了一次测试，我在2月28日和30日在数据库中的会议将在1月份开始。

我可以将日期舍入到当月的第一天吗？

是否有更简单的方法来编写此代码？

PHP代码：

// post variables
$ScoutID=$_POST['ScoutID'];
$Rank=$_POST['Rank'];
$DenID=$_POST['DenID'];
// Define Dates
$Date = date("Y-m-d");
$Month1 = date("Y-m-d", strtotime("-3 months"));
$Month2 = date("Y-m-d", strtotime("-2 months"));
$Month3 = date("Y-m-d", strtotime("-1 months"));
$Month4 = $Date;
$Month5 = date("Y-m-d", strtotime("+1 months"));
$Month6 = date("Y-m-d", strtotime("+2 months"));
$Month7 = date("Y-m-d", strtotime("+3 months"));
$Month8 = date("Y-m-d", strtotime("+4 months"));
$Month9 = date("Y-m-d", strtotime("+5 months"));
$Month10 = date("Y-m-d", strtotime("+6 months"));
$Month11 = date("Y-m-d", strtotime("+7 months"));
$Month12 = date("Y-m-d", strtotime("+8 months"));
$Month12 = date("Y-m-d", strtotime("+9 months"));
//counter variables to print the month header

Answer 1

这是圣诞节，所以你走了。它完成了您所要求的一切（我认为），并增加了一层灵活性。

可以对一些位进行优化，但效果非常好。

$data = array();

// Generate some random dates to simulate database output, then sort.
for($x=0;$x<100;$x++) {
  $day = sprintf("%02s", rand(1,29));
  $month = sprintf("%02s", rand(1,12));
  $year = rand(2011, 2013);
  $data[] = array("Date"=>$year."-".$month."-".$day, "Notes"=>"Entry ".$x);
}

sort($data);

// Calculate start/end timestamps (YYYYMM) according to 
// start/end index prefs and current year
$startIndex = -3;
$endIndex = 9;
$startTimestamp = date("Ym", mktime(0, 0, 0, date('n') + $startIndex, 1, 2012));
$endTimestamp = date("Ym", mktime(0, 0, 0, date('n') + $endIndex, 1, 2012));

// Loop through data
$previous = "";
for($y=0;$y<count($data);$y++) {
  // Create timestamp for comparison (YYYYMM)
  // by removing delimiter in "date" value.
  $entry = $data[$y];
  $date = explode("-", $entry["Date"]);
  $timestamp = $date[0].$date[1];

  // If the timestamp is outside of the start/end timestamps,
  // tell loop to move on to next value
  if($timestamp < $startTimestamp || $timestamp > $endTimestamp) {
    continue;
  }

  // If the timestamp has changed month,
  // output the title of the new month
  if($timestamp != $previous) {
    echo "<br /><b>";
    echo date("F Y", mktime(0, 0, 0, $date[1], 1, $date[0]));
    echo "</b><br />";
  }

  // Finally, output individual values
  echo $entry["Date"].": ".$entry["Notes"]."<br />";

  // Save current timestamp for comparison on the next round
  $previous = $timestamp;
}

编辑第一部分是模拟数据库中的数据，您可以根据需要将其删除。它的核心是中间的for循环。
