PHP简单创建日历的方法

本文实例讲述了PHP简单创建日历的方法。分享给大家供大家参考，具体如下：

    <?php
    function build_calendar($month,$year) {
      // Create array containing abbreviations of days of week.
      $daysOfWeek = array('S','M','T','W','T','F','S');
      // What is the first day of the month in question?
      $firstDayOfMonth = mktime(0,0,0,$month,1,$year);
      // How many days does this month contain?
      $numberDays = date('t',$firstDayOfMonth);
      // Retrieve some information about the first day of the
      // month in question.
      $dateComponents = getdate($firstDayOfMonth);
      // What is the name of the month in question?
      $monthName = $dateComponents['month'];
      // What is the index value (0-6) of the first day of the
      // month in question.
      $dayOfWeek = $dateComponents['wday'];
      // Create the table tag opener and day headers
      $calendar = "<table class='calendar'>";
      $calendar .= "<caption>$monthName $year</caption>";
      $calendar .= "<tr>";
      // Create the calendar headers
      foreach($daysOfWeek as $day) {
         $calendar .= "<th class='header'>$day</th>";
      }
      // Create the rest of the calendar
      // Initiate the day counter, starting with the 1st.
      $currentDay = 1;
      $calendar .= "</tr><tr>";
      // The variable $dayOfWeek is used to
      // ensure that the calendar
      // display consists of exactly 7 columns.
      if ($dayOfWeek > 0) {
         $calendar .= "<td colspan='$dayOfWeek'> </td>";
      }
      $month = str_pad($month, 2, "0", STR_PAD_LEFT);
      while ($currentDay <= $numberDays) {
         // Seventh column (Saturday) reached. Start a new row.
         if ($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>";
         // Increment counters
         $currentDay++;
         $dayOfWeek++;
      }
      // Complete the row of the last week in month, if necessary
      if ($dayOfWeek != 7) {
         $remainingDays = 7 - $dayOfWeek;
         $calendar .= "<td colspan='$remainingDays'> </td>";
      }
      $calendar .= "</tr>";
      $calendar .= "</table>";
      return $calendar;
    }
    //调用方法
    echo build_calendar(05,2016);
    ?>

运行结果如下图所示：
