由两个文件组成：

第一个test.php


php
    include "calendar.class.php";

    $calendar=new Calendar;

    $calendar->out();

第二个日历类：calendar.class.php

php
class Calendar {
        private $year; //当前的年private $month; //当前的月private $start_weekday; //当月的第一天对应的是周几private $days; //当前月一共多少天        function __construct(){

            $this->m>"month"]) ? $_GET["month"] : date("m");
            
            $this->start_weekday=date("w", mktime(0, 0, 0, $this->month, 1, $this->year));
            $this->days=date("t", mktime(0, 0, 0, $this->month, 1, $this->year));
