PHP提供了date()函数,该函数提供了丰富的日期处理功能,现在需要获得的数据有两个,第一个是当月的总天数,第二个是该月的第一天所在星期中的第几天,数字表示0(表示星期天)到6(表示星期六).
通过date()函数可以很容易获得上面的数据,代码如下:
- <?php
- $month = $_GET['m']?$_GET['m']:date(‘n’);
- $year = $_GET['y']?$_GET['y']:date(‘Y’);
- $start_week = date(‘w’,mktime(0,0,0,$month,1,$year));
- $day_num = date(‘t’,mktime(0,0,0,$month,1,$year));
- $end = false;
- ?>
- <table>
- <tr>
- <td>星期日</td><td>星期一</td><td>星期二</td><td>星期三</td><td>星期四</td><td>星期五</td><td>星期六</td>
- </tr>
- <tr>
- <?php
- for($i = 0; $i<$start_week; $i++)
- {
- echo “<td></td>”;
- }
- $j=1;
- while($j<=$day_num)
- {
- echo “<td>$j</td>”;
- $week = ($start_week+$j-1)%7;
- if($week ==6){
- echo “nt</tr>n”;
- if($j != $day_num)
- echo “t<tr>ntt”;
- else $end = true;
- }
- $j++;
- }
- while($week%7 != 6)
- {
- echo “<td></td>”;
- $week++;
- }
- if(!$end)
- echo “n</tr>”;
- ?>
- </table>
- 高级一点类
- 代码如下 复制代码
- <?php
- class Calendar
- {
- private $year;
- private $month;
- private $weeks = array('日','一','二','三','四','五','六');
- function __construct($options = array()) {
- $this->year = date('Y');
- $this->month = date('m');
- $vars = get_class_vars(get_class($this));
- foreach ($options as $key=>$value) {
- if (array_key_exists($key, $vars)) {
- $this->$key = $value;
- }
- }
- }
- function display()
- {
- echo '<table class="calendar">';
- $this->showChangeDate();
- $this->showWeeks();
- $this->showDays($this->year,$this->month);
- echo '</table>';
- }
- private function showWeeks()
- {
- echo '<tr>';
- foreach($this->weeks as $title)
- {
- echo '<th>'.$title.'</th>';
- }
- echo '</tr>';
- }
- private function showDays($year, $month)
- {
- $firstDay = mktime(0, 0, 0, $month, 1, $year);
- $starDay = date('w', $firstDay);
- $days = date('t', $firstDay);
- echo '<tr>';
- for ($i=0; $i<$starDay; $i++) {
- echo '<td> </td>';
- }
- for ($j=1; $j<=$days; $j++) {
- $i++;
- if ($j == date('d')) {
- echo '<td class="today">'.$j.'</td>';
- } else {
- echo '<td>'.$j.'</td>';
- }
- if ($i % 7 == 0) {
- echo '</tr><tr>';
- }
- }
- echo '</tr>';
- }
- private function showChangeDate()
- {
- $url = basename($_SERVER['PHP_SELF']);
- echo '<tr>';
- echo '<td><a href="?'.$this->preYearUrl($this->year,$this->month).'">'.'<<'.'</a></td>';
- echo '<td><a href="?'.$this->preMonthUrl($this->year,$this->month).'">'.'<'.'</a></td>';
- echo '<td colspan="3"><form>';
- echo '<select name="year" onchange="window.location=''.$url.'?year='+this.options[selectedIndex].value+'&month='.$this->month.''">';
- for($ye=1970; $ye<=2038; $ye++) {
- $selected = ($ye == $this->year) ? 'selected' : '';
- echo '<option '.$selected.' value="'.$ye.'">'.$ye.'</option>';
- }
- echo '</select>';
- echo '<select name="month" onchange="window.location=''.$url.'?year='.$this->year.'&month='+this.options[selectedIndex].value+''">';
- for($mo=1; $mo<=12; $mo++) {
- $selected = ($mo == $this->month) ? 'selected' : '';
- echo '<option '.$selected.' value="'.$mo.'">'.$mo.'</option>';
- }
- echo '</select>';
- echo '</form></td>';
- echo '<td><a href="?'.$this->nextMonthUrl($this->year,$this->month).'">'.'>'.'</a></td>';
- echo '<td><a href="?'.$this->nextYearUrl($this->year,$this->month).'">'.'>>'.'</a></td>';
- echo '</tr>';
- }
- private function preYearUrl($year,$month)
- {
- $year = ($this->year <= 1970) ? 1970 : $year - 1 ;
- return 'year='.$year.'&month='.$month;
- }
- private function nextYearUrl($year,$month)
- {
- $year = ($year >= 2038)? 2038 : $year + 1;
- return 'year='.$year.'&month='.$month;
- }
- private function preMonthUrl($year,$month)
- {
- if ($month == 1) {
- $month = 12;
- $year = ($year <= 1970) ? 1970 : $year - 1 ;
- } else {
- $month--;
- }
- return 'year='.$year.'&month='.$month;
- }
- private function nextMonthUrl($year,$month)
- {
- if ($month == 12) {
- $month = 1;
- $year = ($year >= 2038) ? 2038 : $year + 1;
- }else{
- $month++;
- }
- return 'year='.$year.'&month='.$month;
- }
- }
- 调用方法
- 代码如下 复制代码
- <?php
- $params = array();
- if (isset($_GET['year']) && isset($_GET['month'])) {
- $params = array(
- 'year' => $_GET['year'],
- 'month' => $_GET['month'],
- );
- }
- $params['url'] = 'demo.php';
- require_once 'calendar.class.php';
- ?>
- <html>
- <head>
- <title>日历demo</title>
- <meta http-equiv="Content-Type" content="text/html" charset="UTF-8" />
- <style type="text/css">
- table.calendar {
- border: 1px solid #050;
- }
- .calendar th, .calendar td {
- width:30px;
- text-align:center;
- }
- .calendar th {
- background-color:#050;
- color:#fff;
- }
- .today{
- color:#fff;
- background-color:#050;
- //开源代码phpfensi.com
- }
- </style>
- </head>
- <body>
- <div style="align:center">
- <?php
- $cal = new Calendar($params);
- $cal->display();
- ?>
- </div>
- </body>
