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 | |
$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));
$end = false;
?>
星期日 | 星期一 | 星期二 | 星期三 | 星期四 | 星期五 | 星期六 |
for($i = 0; $i<$start_week; $i++)
{
echo “ | ”;
}$j=1; while($j<=$day_num)
{
echo “ $j | ”;
$week = ($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 ”;
?>
|
高级一点类
| 代码如下 | |
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,$this->month);
echo ' ';
}
private function showWeeks()
{
echo ' |
';
foreach($this->weeks as $title)
{
echo ''.$title.' | ';
}
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; $i<$starDay; $i++) {
echo ' | ';
}
for ($j=1; $j<=$days; $j++) {
$i++;
if ($j == date('d')) {
echo ''.$j.' | ';
} else {
echo ''.$j.' | ';
}
if ($i % 7 == 0) {
echo '
';
}
}
echo '
';
}
private function showChangeDate()
{
$url = basename($_SERVER['PHP_SELF']);
echo '';
echo 'preYearUrl($this->year,$this->month).'">'.'<<'.' | ';
echo 'preMonthUrl($this->year,$this->month).'">'.'<'.' | ';
echo ' | ';
echo 'nextMonthUrl($this->year,$this->month).'">'.'>'.' | ';
echo 'nextYearUrl($this->year,$this->month).'">'.'>>'.' | ';
echo '
';
}
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 | |
$params = array();
if (isset($_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();
?>
