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

复制代码

$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;
?>

for($i = 0; $i{
echo “”;
}

$j=1;

while($j{
echo “

”;
$week = ($start_week+$j-1)%7;

if($week ==6){
echo “nt

n”;
if($j != $day_num)
echo “tntt”;
else $end = true;
}
$j++;
}
while($week%7 != 6)
{
echo “”;
$week++;
}
if(!$end)
echo “n”;
?>

星期日	星期一	星期二	星期三	星期四	星期五	星期六
	$j

高级一点类

';
        foreach($this->weeks as $title)
        {
            echo '';
        }
        echo '';
    }

    private function showDays($year, $month)
    {
        $firstDay = mktime(0, 0, 0, $month, 1, $year);
        $starDay = date('w', $firstDay);
        $days = date('t', $firstDay);

echo '

        for ($i=0; $i            echo '';
        }

        for ($j=1; $j            $i++;
            if ($j == date('d')) {
                echo '';
            } else {
                echo '';
            }
            if ($i % 7 == 0) {
                echo '';
            }
        }

        echo '';
    }

    private function showChangeDate()
    {

        $url = basename($_SERVER['PHP_SELF']);

        echo '';
echo '';

        echo '';

        echo '';
    }

    private function preYearUrl($year,$month)
    {
        $year = ($this->year
        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         } 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;
    }

}

代码如下

复制代码

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 '

';
        $this->showChangeDate();
        $this->showWeeks();
        $this->showDays($this->year,$this->month);
        echo '

';
    }

    private function showWeeks()
    {
        echo '

'.$title.'

'.$j.'

'.'

'.'>'.'

'.'>>'.'

调用方法

代码如下

复制代码

$params = array();
if (isset($_GET['year']) && isset($_GET['month'])) {
    $params = array(
        'year' => $_GET['year'],
        'month' => $_GET['month'],
    );
}
$params['url'] = 'demo.php';
require_once 'calendar.class.php';
?>

        日历demo

                            $cal = new Calendar($params);
                $cal->display();
            ?>
