您忘记在while()代码中的索引名称周围添加引号。
例如：-$row[id]需要是$row['id']
如下所示：-
while($row = mysqli_fetch_assoc( $result )) {
// set up a row for each record
echo '<tr>';
echo '<td>' . $row['id'] . '</td>';
echo '<td>' . $row['department'] . '</td>';
echo '<td>' . $row['custodian'] . '</td>';
echo '<td>' . $row['location'] . '</td>';
echo '<td>' . $row['brand'] . '</td>';
echo '<td>' . $row['model'] . '</td>';
echo '<td>' . $row['hardwaresn'] . '</td>';
echo '<td>' . $row['hardisk'] . '</td>';
echo '<td>' . $row['processor'] . '</td>';
echo '<td>' . $row['ram'] . '</td>';
echo '<td>' . $row['monitor'] . '</td>';
echo '<td>' . $row['actualos'] . '</td>';
echo '<td>' . $row['msoffice'] . '</td>';
echo '<td>' . $row['supplier'] . '</td>';
echo '<td>' . $row['invoicenumber'] . '</td>';
echo '<td>' . $row['purchasedate'] . '</td>';
echo '<td>' . $row['warranty'] . '</td>';
echo '<td><a href="edit.php?id=' . $row['id'] . '">Edit</a></td>';
echo '<td><a href="delete.php?id=' . $row['id'] . '">Delete</a></td>';
echo '</tr>';
}
注意：-使用mysqli_fetch_assoc()而不是mysqli_fetch_array，因此只会出现关联数组。
