用PHP实现日历类的编写，供大家参考，具体内容如下

calendar.class.php

<"PRC");
 
 class Calendar {
  private $year;
 private $month;
 private $day; //当月总天数
 private $first_week; //每月的第一天是星期几
 
 //构造函数
 function __construct() {
  $this->year = isset($_GET['year'])"Y");
  $this->month = isset($_GET["month"])"month"]:date("m");
  $this->first_week = date("w", mktime(0, 0 ,0, $this->month, 1, $this->year));
  $this->day = date("t", mktime(0, 0 ,0, $this->month, 1, $this->year));
 }
 function showCalendar() {
 //  echo $this->year."年".$this->month."月".$this->first_week."天".$this->day;
   echo "<table align='center'>"; //用表格输出
   $this->chageDate("index.php"); //用于用户调整年月份
  $this->weekList();//显示星期
  $this->dayList(); //显示天数
  
  echo "</table>";
 }
 //1、显示星期
 private function weekList() {
  $week = array("日","一","二","三","四","五","六");
  echo "<tr>";
   for ($i = 0; $i < count($week); $i++) {
   echo "<th>".$week[$i]."</th>";
  }
  echo "</tr>";
 }
 //2.显示天数
 private function dayList() {
  $color = "#2ca50c";
  echo "<tr>";
  for ($i = 0; $i < $this->first_week; $i++) { //输出空格，弥补当前月空缺部分
   echo "<td bgcolor='#2ca50c'> </td>";
  }
  for ($k = 1; $i <= $this->day; $k++) {
   $i++;
   if ($k == date("d")) echo "<td id='nowd'>".$k."</td>"; //是今天，加效果
   else echo "<td bgcolor=$color>".$k."</td>";
   if ($i % 7 == 0) {
   echo "</tr><tr>"; //每7天一次换行
   if ($i % 2 == 0) $color = "#2ca50c";
   else $color = "#9ddb27"; //实现各行换色的效果
   }
  }
  while ($i % 7 != 0) { //将剩余的空格补完
   echo "<td bgcolor='#2ca50c'> </td>";
  $i++; 
  }
  echo "</tr>";
 }
  
 //3、用于用户调整天数
 private function chageDate($url="index.php") {
  echo "<tr>";
   echo "<caption><h1>".$this->year."年".$this->month."月</h1></caption>"; 
  echo "</tr>";
  echo "<tr>";
  echo "<td>"."<a href='".$this->prevYear($this->year,$this->month)."'>"."<"."</a>";
  echo "<td>"."<a href='".$this->prevMonth($this->year,$this->month)."'>"."<<"."</a>";
  
  echo "<td colspan='3'>";
   echo '<select οnchange="window.location=\''.$url.'">';
    for ($year = 2038; $year >= 1970; $year--) {
    $selected = ($year == $this->year)"selected":"";
    echo '<option '.$selected. ' value="'.$year.'">'.$year.'</option>';
    //echo '<option '.$selected.' value="'.$year.'">'.$year.'</option>';
   }
   echo "</select>";
   
  echo '<select name="month" οnchange="window.location=\''.$url.'">';
  for($month=1;$month <= 12;$month++){
   $selected1 = ($month == $this->month) "selected" : "";
   echo '<option '.$selected1.' value="'.$month.'">'.$month.'</option>';
  }
  echo '</select>';
  echo "</td>";
  
  
  echo "<td>"."<a href='".$this->nextMonth($this->year,$this->month)."'>".""."</a>";
  echo "<td>"."<a href='".$this->nextYear($this->year,$this->month)."'>".">"."</a>";
  echo "</tr>";
 }
 
 private function prevYear($year, $month) { //获取上一年的数据
  $year--;
  if ($year < 1970) $year = 1970;
  return "year={$year}&month={$month}";
 }
 private function prevMonth($year, $month) {
  if ($month == 1) {
   $year--;
  if ($year < 1970) $year = 1970;
  $month = 12;
  }else $month--; 
  return "year={$year}&month={$month}";
 }
 private function nextYear($year, $month) { //获取上一年的数据
  $year++;
  if ($year > 2038) $year = 2038;
  return "year={$year}&month={$month}";
 }
 private function nextMonth($year, $month) {
  if ($month == 12) {
   $year++;
  if ($year > 2038) $year = 2038;
  $month = 1;
  }else $month++; 
  return "year={$year}&month={$month}";
 }
 }

稳了！魔兽国服回归的3条重磅消息！官宣时间再确认！

昨天有一位朋友在大神群里分享，自己亚服账号被封号之后居然弹出了国服的封号信息对话框。

这里面让他访问的是一个国服的战网网址，com.cn和后面的zh都非常明白地表明这就是国服战网。
而他在复制这个网址并且进行登录之后，确实是网易的网址，也就是我们熟悉的停服之后国服发布的暴雪游戏产品运营到期开放退款的说明。这是一件比较奇怪的事情，因为以前都没有出现这样的情况，现在突然提示跳转到国服战网的网址，是不是说明了简体中文客户端已经开始进行更新了呢？
