简单实用PHP日历程序代码-php教程

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 >';
$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" >';
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.'">'.$i.'年</option>';
}
}
echo '</select>';
echo '<select name="month" onchange="formaction()">';
for ($i = $this->yearMonth[3]; $i <= $this->yearMonth[2]; $i++) {
if ($i == $this->month) {
echo '<option value="'.$i.'" selected="selected">'.$i.'月</option>'; //开源软件:phpfensi.com
}else {
echo '<option value="'.$i.'">'.$i.'月</option>';
}
}
echo '</select></form></td>';
echo '<td><a title="下一月" href="?year='.$this->year.'&month='.($this->month+1).'">></a></td>';
echo '<td><a title="下一年" href="?year='.($this->year+1).'&month='.$this->month.'">>></a></td>';
echo '</tr>';
echo '<tr>';
//输出空格（当前一个月第一天前面要空出来的）
for($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>';
}
}
}
echo '</tr>';
}
}
?>
