我创建了一个 php 日历，一次显示一周.这是我创建的代码

I have created a php calender which will show one week at a time.Here is the code i have created

<?php $week = date("W"); $year = (isset($_GET['year']))?$_GET['year']:date("Y"); $week = (isset($_GET['week']))?$_GET['week']:Date('W'); if($week>53){ $year+= 1; $week=1; } ?> <a href="<?php echo $_SERVER['PHP_SELF'].'?week='.($week+1).'&year='.$year; ?>">Next Week</a> <!--Next week--> <a href="<?php echo $_SERVER['PHP_SELF'].'?week='.($week-1).'&year='.$year; ?>">Pre Week</a> <!--Previous week--> <table border="1px"> <tr> <td>Employee</td> <?php for($day=1; $day<=7; $day++) { $d = strtotime($year."W".$week.$day); echo "<td>".date('l',$d )."<br>"; echo date('d M',$d)."</td>"; } ?> </tr>

当我试图去下周时，它工作正常.但是当年份变化时，它不适用于明年.

when i am trying to go to the next week it is working correctly. But when the year is changing it is not working for the next year.

推荐答案

将周计算留给 DateTime::setIsoDate() 方法.

Leave the week calculation to the DateTime::setIsoDate() method.

这是解决您问题的最简单和最佳的解决方案:

Here is the simplest and best solution for your problem :

<?php $dt = new DateTime; if (isset($_GET['year']) && isset($_GET['week'])) { $dt->setISODate($_GET['year'], $_GET['week']); } else { $dt->setISODate($dt->format('o'), $dt->format('W')); } $year = $dt->format('o'); $week = $dt->format('W'); ?> <a href="<?php echo $_SERVER['PHP_SELF'].'?week='.($week-1).'&year='.$year; ?>">Pre Week</a> <!--Previous week--> <a href="<?php echo $_SERVER['PHP_SELF'].'?week='.($week+1).'&year='.$year; ?>">Next Week</a> <!--Next week--> <table> <tr> <td>Employee</td> <?php do { echo "<td>" . $dt->format('l') . "<br>" . $dt->format('d M Y') . "</td> "; $dt->modify('+1 day'); } while ($week == $dt->format('W')); ?> </tr> </table>
