請問PHP資料庫

Jun 10th 2013, 02:59

$link = mysql_connect("localhost","root","root");

if (mysqli_connect_errno($link))
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$db_selected=mysql_select_db("pd",$link);
if (mysql_errno($link))
{
echo "NO". mysql_error();
}
// Assign the query
$query = "select PD_Name,N1 from pd_realtime_status where PD_Name='PD01' " ;
// Execute the query
$result = mysql_query($query,$link);
if (!$result){
die ("Could not query the database: <br />". mysql_error());
}
?>
<table>
<tr>
<th></th>
</tr>
<?php

$x = $row["N1"];

if ($x=="0")
echo "!";
elseif ($x=="1")
echo "!!";
else
echo "!!!";

請問各位大大我想要取pd_realtime_status裡面的PD01的N1哪個欄位的數值判斷
是1還是0我上面得語法有哪邊打錯嗎?或是需要修改的我的程式成功執行只會出現"!"就算我資料庫內是0 PS.我資料庫PD_Name欄位有16個每個都有4個小欄位
