Question

我似乎无法找到需要半冒号或“}”的地方

for ($period=1; $period<6; $period++)
  {
     echo "<tr><td>".$period."</td>";  
     for ($room=0; $room<sizeof($rooms_array); $room++)
       {
         $sql = "SELECT Username FROM Booking WHERE RoomID ='".$rooms_array[$room]."' AND Period = '".$period."' AND Date = '".$sentdate."'";
         $result= sqlite_query($con,$sql);
         $row = sqlite_fetch_array($result);
         if($row['Username']==$_SESSION['Username'])
           {
             echo "<td>Booked By ".$row['Username']."</td>"
           }
       }
   }    

?>

Answer 1

你的echo语句后需要一个分号：

{echo "<td>Booked By ".$row['Username']."</td>";}

如果采用更清晰的块/缩进样式，可能更容易找到这样的错误。你的代码很难阅读。

例如：

for ($period=1; $period<6; $period++)
{
    echo "<tr><td>".$period."</td>";  
    for ($room=0; $room<sizeof($rooms_array); $room++)
    {
        $sql = "SELECT Username FROM Booking WHERE RoomID ='".$rooms_array[$room]."' AND Period = '".$period."' AND Date = '".$sentdate."'";
        $result= sqlite_query($con,$sql);
        $row = sqlite_fetch_array($result);
        if($row['Username']==$_SESSION['Username'])
        {
            echo "<td>Booked By ".$row['Username']."</td>";
        }
    }
}

Answer 2

此处缺少;：

{echo "<td>Booked By ".$row['Username']."</td>"}
                                              ^

Answer 3

echo "<td>Booked By ".$row['Username']."</td>"缺少分号

知道为什么我的代码会产生语法错误吗？
