Question

我正在尝试使用php创建一个时间跟踪系统，其中我有两个按钮，如时钟输入和时钟输出。我在时间中存储时钟并在会话变量中输出时间。现在我的要求是计算时钟和时钟输出时间之间的差异。如果您对计算时间差异有清晰的认识，请与我分享想法

<?php
if(isset($_POST['start']))
{
  date_default_timezone_set('Asia/Calcutta'); 
  $time_start=date("Y-m-d h:i:s A"); 
  setcookie('start',$time_start,time()+(36400)*3,'/');
  echo "time start now ".$time_start."<br>"; 
}
if(isset($_POST['end']))
{
  date_default_timezone_set('Asia/Calcutta'); 
  $time_end=date("Y-m-d h:i:s A"); 
  setcookie('end',$time_end,time()+(36400)*3,'/');
  echo "time was ended".$time_end."<br>"; 
?>
<html>
  <body>
    <form  method="POST">
      <input type="submit" name="start" value="Start">
      <br><br>
      <input type="submit" name="end" value="End">
    </form>
  </body>
</html>

DateTime类有多种方法可以使日期工作变得非常简单。也许以下内容将说明如何实现目标。

$format='Y-m-d H:i:s';
$timezone=new DateTimeZone('Asia/Calcutta');

$clockin = new DateTime( date( $format, strtotime( $_COOKIE['start'] ) ),$timezone );
$clockout= new DateTime( date( $format, strtotime( $_COOKIE['end'] ) ), $timezone );

$diff=$clockout->diff( $clockin );

echo $diff->format('%h hours %i minutes %s seconds');

为了完全测试我快速写了 - 看起来工作得很好！

<?php
    $cs='shift_start';
    $cf='shift_end';

    date_default_timezone_set('Europe/London'); 

    if( isset( $_POST['start'] ) ){
      setcookie( $cs, date("Y-m-d h:i:s A"), time()+(36400)*3,'/');
    }
    if( isset( $_POST['end'] ) ){
      setcookie( $cf, date("Y-m-d h:i:s A"), time()+(36400)*3,'/');
    }
?>
