php日历是一个很简单但很实用的函数，如果打算自己写网站源代码的朋友可以看看。笔者没有添加样式，尽量保持代码的简洁，如果需要美化，可自行添加css代码^{_^{。输出的效果如下：}}

<?php

function build_calendar($month,$year,$dateArray) {
 // 日历表头，星期天开始一直到星期六
     $daysOfWeek = array('S','M','T','W','T','F','S');

     // 本月第一天的位置
     $firstDayOfMonth = mktime(0,0,0,$month,1,$year);

     // 获取本月天数
     $numberDays = date('t',$firstDayOfMonth);

 // 获取本月第一天
     $dateComponents = getdate($firstDayOfMonth);

     // 获取月份的英文单词
     $monthName = $dateComponents['month'];

     $dayOfWeek = $dateComponents['wday'];

     // 月历表头

     $calendar = "<table class='calendar'>";
     $calendar .= "<caption>$monthName $year</caption>";
     $calendar .= "<tr>";

     // 星期表头

     foreach($daysOfWeek as $day) {
          $calendar .= "<th class='header'>$day</th>";
     }

     // 开始输出日历

     // 初始化天数计数器，从1号开始

     $currentDay = 1;

     $calendar .= "</tr><tr>";

     // 使用变量 $dayOfWeek 可以保证一周七天精确输出

     if ($dayOfWeek > 0) {
          $calendar .= "<td colspan='$dayOfWeek'>&nbsp;</td>";
     }

     $month = str_pad($month, 2, "0", STR_PAD_LEFT);

     while ($currentDay <= $numberDays) {

          // 7天一行，7天一到新增一行

          if ($dayOfWeek == 7) {

               $dayOfWeek = 0;
               $calendar .= "</tr><tr>";

          }

          $currentDayRel = str_pad($currentDay, 2, "0", STR_PAD_LEFT);

          $date = "$year-$month-$currentDayRel";

          $calendar .= "<td class='day' rel='$date'>$currentDay</td>";

          // 计数器

          $currentDay++;
          $dayOfWeek++;

     }

     // 最后一行表格的处理，往往最后一行不可能全部填满，需要要空格填充。

     if ($dayOfWeek != 7) {

          $remainingDays = 7 - $dayOfWeek;
          $calendar .= "<td colspan='$remainingDays'>&nbsp;</td>";

     }

     $calendar .= "</tr>";

     $calendar .= "</table>";

     return $calendar;
}

?>

用法

<?php

$dateComponents = getdate();
$month = $dateComponents['mon'];
$year = $dateComponents['year'];
echo build_calendar($month,$year,$dateArray);

?>
