精美PHP日历程序

分享一款PHP日历程序,功能都是大众化的,可以下拉切换年月,上一年下一月下一年上一月,太另类的没去写,主要的写出来了,扩展起来就方便多了,标题为什么要叫精美呢,是因自已感觉界面还过得去,哈哈,让大家见笑了,不足之处还请指出。

日历程序

日历类部分:

<?php
//日历类
class calendar {
    //当前的年
    private $year;
    //当前的月
    private $month;
    //一个月中第一天是星期几
    private $start_weekday;
    //当前月的天数
    private $days;
    //最大数与最小年数,最大与最小月数
    private $yearMonth = array(2080, 1900, 12, 1);
    //构造函数
    function __construct() {
        if (isset($_GET['year'])) {
           $this->year = $_GET['year'];
        }
            if (isset($_GET['month'])) {

        }
        $this->pnYm($this->year, $this->month);
        $this->days = date('t', mktime(0, 0, 0, $this->month, 1, $this->year));
        $this->start_weekday = date('w', mktime(0, 0, 0, $this->month, 1, $this->year));

    }
    //输出

$calendar = new calendar();
?>

这代码不会自动排版,一个个空格敲真是痛苦。。。。
