简单实用PHP日历程序代码
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入门小编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。
效果代码如下
php日历核心代码
<?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.'">'.$i.'年</option>'; } } echo '</select>'; echo '<select name="month" onchange="formaction()">'; for ($i = $this->yearMonth[3]; $i <= $this->yearMonth[2]; $i++) { if ($i == $this->month) { echo '<option value="'.$i.'" selected="selected">'.$i.'月</option>'; }else { echo '<option value="'.$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>'; } } ?>
