我怎樣才能得到這兩個時間值之間的差異？確切的小時，分​​鍾，秒

Question

$timein = date('h:i:s a',strtotime($jrow['time_in'])); 
$timeout = date('h:i:s a',strtotime($jrow['time_out'])); 
$diff = $timeout - $timein; 
echo "<td>".date('h:i:s', $diff)."</td>";

Answer 1

你可以通過下面的功能完整的時間差

function date_getFullTimeDifference($start, $end) 
{ 
$uts['start']  = strtotime($start); 
     $uts['end']  = strtotime($end); 
     if($uts['start']!==-1 && $uts['end']!==-1) 
     { 
      if($uts['end'] >= $uts['start']) 
      { 
       $diff = $uts['end'] - $uts['start']; 
       if($years=intval((floor($diff/31104000)))) 
        $diff = $diff % 31104000; 
       if($months=intval((floor($diff/2592000)))) 
        $diff = $diff % 2592000; 
       if($days=intval((floor($diff/86400)))) 
        $diff = $diff % 86400; 
       if($hours=intval((floor($diff/3600)))) 
        $diff = $diff % 3600; 
       if($minutes=intval((floor($diff/60)))) 
        $diff = $diff % 60; 
       $diff = intval($diff); 
       return(array('years'=>$years,'months'=>$months,'days'=>$days, 'hours'=>$hours, 'minutes'=>$minutes, 'seconds'=>$diff)); 
      } 
      else 
      { 
       echo "Ending date/time is earlier than the start date/time"; 
      } 
     } 
     else 
     { 
      echo "Invalid date/time data detected"; 
     } 
}
