php简单的日历程序代码

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 '';
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();
?>
