日历程序代码我们一般会使用一些js插件来实现了,但是像博客这种日志分类我们会使用php程序来实现,下面php粉丝网就来为你介绍一下吧.

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.

php日历核心代码如下:

<?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->month = $_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));

        $this->style();

    }

    //输出

    private function style() {

        echo '<table id="calendar">';

        $this->weeklist();

        $this->daylist();

        echo '<table>';

    }

    //年月参数判断

    private function ymCheck($year, $month) {

        if (!is_numeric($year)) {

            $year = date('Y');

        }

        if (!is_numeric($month)) {

            $month = date('m');

        }

        if ($month < $this->yearMonth[3]) {

            $month = $this->yearMonth[2];

            $year -= 1;

        }

        if ($month > $this->yearMonth[2]) {

            $month = $this->yearMonth[3];

            $year = intval($year) + 1;

        }

        $year = $year < $this->yearMonth[1] ? $this->yearMonth[1] : $year;

        $year = $year > $this->yearMonth[0] ? $this->yearMonth[0] : $year;

        return array($year, $month);

    }

    //上一年、下一年、上一月、下一月

    private function pnYm($year, $month) {

        $ym = $this->ymCheck($year, $month);

        $this->year = $ym[0];

        $this->month = $ym[1];

    }

    //weeklist周列表

    private function weeklist() {

        $week = array('日','一','二','三','四','五','六');

        echo '<tr>';

        foreach ($week as $val) {

            echo '<th>'.$val.'</th>';

        }

        echo '</tr>';

    }

    //daylist天列表

    private function daylist() {

        //年月日导航

        echo '<tr>';

        echo '<td><a title="上一年" href="?year='.($this->year-1).'&month='.$this->month.'"><<</a></td>';

        echo '<td><a title="上一月" href="?year='.$this->year.'&month='.($this->month-1).'"><</a></td>';

        echo '<td colspan="3">';

        echo '<form action="?" method="get" id="form">';

        echo '<select name="year" onchange="formaction()">';

        for ($i = $this->yearMonth[1]; $i <= $this->yearMonth[0]; $i++) {

             if ($i == $this->year) {

                   echo '<option value="'.$i.'" selected="selected">'.$i.'年</option>';

             }else {

                   echo '<option value="'.$i.'">'.$i.'年</option>';

       echo '</tr>';

       echo '<tr>';

       //输出空格（当前一个月第一天前面要空出来的）

       for($i = 0; $i < $this->start_weekday; $i++) {

             echo '<td> </td>';

       }

       for ($k = 1; $k <= $this->days; $k++) {

            $i++;

            if ($k == date('d')) {

                  echo '<td>'.$k.'</td>';

            }else {

                  echo '<td>'.$k.'</td>';

            }

            if ($i % 7 == 0) {

                 if ($k != $this->days) {

                        echo '</tr><tr>';
