PHP實現簡單日歷類編寫
用PHP實現日歷類的編寫，供大家參考，具體內容如下
calendar.class.php
<?php/** 創建一個日歷類***/ //修改默認時區 date_default_timezone_set('PRC'); class Calendar { private $year; private $month; private $day; //當月總天數 private $first_week; //每月的第一天是星期幾 //構造函數 function __construct() { $this->year = isset($_GET[’year’])?$_GET[’year’]:date('Y'); $this->month = isset($_GET['month'])?$_GET['month']:date('m'); $this->first_week = date('w', mktime(0, 0 ,0, $this->month, 1, $this->year)); $this->day = date('t', mktime(0, 0 ,0, $this->month, 1, $this->year)); } function showCalendar() { // echo $this->year.'年'.$this->month.'月'.$this->first_week.'天'.$this->day; echo '<table align=’center’>'; //用表格輸出 $this->chageDate('index.php'); //用于用戶調整年月份 $this->weekList();//顯示星期 $this->dayList(); //顯示天數 echo '</table>'; } //1、顯示星期 private function weekList() { $week = array('日','一','二','三','四','五','六'); echo '<tr>'; for ($i = 0; $i < count($week); $i++) { echo '<th>'.$week[$i].'</th>'; } echo '</tr>'; } //2.顯示天數 private function dayList() { $color = '#2ca50c'; echo '<tr>'; for ($i = 0; $i < $this->first_week; $i++) { //輸出空格，彌補當前月空缺部分 echo '<td bgcolor=’#2ca50c’> </td>'; } for ($k = 1; $i <= $this->day; $k++) { $i++; if ($k == date('d')) echo '<td id=’nowd’>'.$k.'</td>'; //是今天，加效果 else echo '<td bgcolor=$color>'.$k.'</td>'; if ($i % 7 == 0) { echo '</tr><tr>'; //每7天一次換行 if ($i % 2 == 0) $color = '#2ca50c'; else $color = '#9ddb27'; //實現各行換色的效果 } } while ($i % 7 != 0) { //將剩余的空格補完 echo '<td bgcolor=’#2ca50c’> </td>'; $i++; } echo '</tr>'; } //3、用于用戶調整天數 private function chageDate($url='index.php') { echo '<tr>'; echo '<caption><h1>'.$this->year.'年'.$this->month.'月</h1></caption>'; echo '</tr>'; echo '<tr>'; echo '<td>'.'<a href=’?'.$this->prevYear($this->year,$this->month).'’>'.'<'.'</a>'; echo '<td>'.'<a href=’?'.$this->prevMonth($this->year,$this->month).'’>'.'<<'.'</a>'; echo '<td colspan=’3’>'; echo ’<select οnchange='window.location=’’.$url.’?year=’+this.options[selectedIndex].value+’&month=’.$this->month.’’'>’; for ($year = 2038; $year >= 1970; $year--) { $selected = ($year == $this->year)?'selected':''; echo ’<option ’.$selected. ’ value='’.$year.’'>’.$year.’</option>’; //echo ’<option ’.$selected.’ value='’.$year.’'>’.$year.’</option>’; } echo '</select>'; echo ’<select name='month' οnchange='window.location=’’.$url.’?year=’.$this->year.’&month=’+this.options[selectedIndex].value'>’; for($month=1;$month <= 12;$month++){ $selected1 = ($month == $this->month) ?
