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; $i<$start_week; $i++)
{
echo “”;
}

$j=1;

while($j<=$day_num)
{
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”;
?>

            }
        }
    }
   
    function display()
    {
        echo '

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

 '.$j.''.$j.'
'.'<<'.''.'<'.'
';
       
        echo '';
        echo '';       
        echo '
'.'>'.''.'>>'.'

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();
            ?>
