日历类实现
1、输出星期
calendar.class.php
1 <?php
2 class Calendar{
3
4 function out(){//输出表格
5 echo ‘<table align="center">‘;
6 $this->weeksList(); //输出星期
7 8 echo ‘</table>‘;
9 }
10 private function weeksList(){
11
12 $week=array(‘日‘,‘一‘,‘二‘,‘三‘,‘四‘,‘五‘,‘六‘);
13 echo ‘<tr>‘;
14 for($i=0;$i<count($week);$i++)
15 echo ‘<th class="fontb">‘.$week[$i].‘</th>‘;
16 echo ‘</tr>‘;
17 }
18 19 20 ?>
index.php
1 <style> //样式
2 table {
3 border:1px solid #050; //边框，050:绿色
4 }
5 .fontb {
6 color:white;
7 background:blue;
8 }
9
10 th {
11 width=30px;height=30px;
12 }
13 </style>
14 <?php
15 include "calendar.class.php";
16
17 $calendar=new Calendar;
18 $calendar->out();
19 ?
2、输出日期
calendar.class.php
1 <?php
2 class Calendar{
3 private $year;
4 private $month;
5 private $start_weekday; // 当月的第一天是周几
6 private $days;//当前月有几天
7
8 function __construct(){

10 $this->month=date("m");
11
12 $this->start_weekday=date("w",mktime(0,0,0,$this->month,1,$this->year));
13 $this->days=date("t",mktime(0,0,0,$this->month,1,$this->year));
14 }
15
16 function out(){//输出表格
17 echo ‘<table align="center">‘;
18 $this->weeksList();
19 $this->daysList();
20 echo ‘</table>‘;
21 }
22 private function weeksList(){
23
24 $week=array(‘日‘,‘一‘,‘二‘,‘三‘,‘四‘,‘五‘,‘六‘);
25 echo ‘<tr>‘;
26 for($i=0;$i<count($week);$i++)
27 echo ‘<th class="fontb">‘.$week[$i].‘</th>‘;
28 echo ‘</tr>‘;
29 }
30 private function daysList(){
31 echo ‘<tr>‘;
32 for($j=0;$j<$this->start_weekday;$j++)
33 echo ‘<td> </td>‘; //输出空格
34
35 for($k=1;$k<=$this->days;$k++){
36 $j++;
37 if($k==date(‘d‘)) //当前天显示颜色
38 echo ‘<td class="fontb">‘.$k.‘</td>‘;
39 else
40 echo ‘<td>‘.$k.‘</td>‘;
41 if ($j%7==0)
42 echo ‘</tr><tr>‘;
43 }
44 echo ‘</tr>‘;
45 }
46 }
47 ?>
test.php
1 <style>
2 table {
3 border:1px solid #050;
4 }
5 .fontb {
6 color:white;
7 background:blue;
8 }
9
10 th {

4、增加年月选择下拉列表 *
