我想在index.php中显示2个表。显示来自1个数据库的相同数据。但它没有出现。见下面在index.php中显示2个表mysql
这里形象是我的代码（的index.php）
<?php
\t include("dbcon.php"); \t
\t
\t $link=$cn;
$i=0;
\t $result=mysqli_query($link,"SELECT * FROM `node` ORDER BY `tarikh` DESC LIMIT 1");
\t
?>
<html>
<head>
<title>Sensor Data1</title>
<meta http-equiv="refresh" content="30">
</head>
<body>
<Center><h1>Sensor Readings</h1>
<h1>Node 1</h2>
<table border="2" cellspacing="2" cellpadding="2">
\t \t <tr>
\t \t \t <td> No </td>
\t \t \t <td> Waktu/Tarikh </td>
\t \t \t <td> Temperature </td>
\t \t \t <td> Humidity </td>
\t \t \t <td> Length(CM) </td>
\t \t \t <td> Node </td> \t
\t \t </tr>
\t \t
<?php
\t \t while($row = mysqli_fetch_array($result)) {
\t \t printf("<tr><td> %d </td><td> %s </td><td> %s </td><td> %s </td><td> %s </td><td> %s </td></tr>",
\t \t ++$i, $row["tarikh"], $row["temperature"], $row["humidity"], $row["height"], $row["node"]);
\t \t } \t \t
\t \t
?>
</table></center>
<center><table border="2" cellspacing="2" cellpadding="2">
\t \t <tr>
\t \t \t <td> No </td>
\t \t \t <td> Waktu/Tarikh </td>
\t \t \t <td> Temperature </td>
\t \t \t <td> Humidity </td>
\t \t \t <td> Length(CM) </td>
\t \t \t <td> Node </td> \t
\t \t </tr>
\t \t
\t \t <?php
\t \t while($row = mysqli_fetch_array($result)) {
\t \t printf("<tr><td> %d </td><td> %s </td><td> %s </td><td> %s </td><td> %s </td><td> %s </td></tr>",
\t \t ++$i, $row["tarikh"], $row["temperature1"], $row["humidity1"], $row["height"], $row["node"]);
\t \t } \t \t
\t \t
?></center>
