php简单的日历程序代码_PHP教程

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

        }else{
            $month++;
        }
        return 'year='.$year.'&month='.$month;
    }

 代码如下

复制代码

    private $year;
    private $month;
    private $weeks  = array('日','一','二','三','四','五','六');
   
    function __construct($options = array()) {

        $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);

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