echo "<td> $row['fname'] </td>"; 
echo "<td> $row['name'] </td>"; 

} 

echo "</tr>"; 
echo "</table>"; 

?> 

Answer 1

试试这个

echo "<td>" . $row['fname'] . "</td>"; 

Answer 2

更改while循环此

while ($row = $result->fetch_assoc()) { 

    echo "<td>". $row['fname'] ."</td>"; 
    echo "<td>". $row['fname'] ."</td>"; 
    echo "<td>". $row['name'] ."</td>"; 

} 

Answer 3

Read the manual for the correct syntax用于在字符串中嵌入数组值，"$arr['key']"是而不是正确的两种方法之一。

这是不是

"$arr[key]" 

或

"{$arr['key']}" 

Answer 4

你应该行使用此代码24

echo "<td> $row[fname] </td>"; 
    echo "<td> $row[fname] </td>"; 
    echo "<td> $row[name] </td>"; 

Answer 5

您也可以使用此：

while ($row = $result->fetch_assoc()) { 

    echo "<td>{$row['fname']}</td>"; 
    echo "<td>{$row['fname']}</td>"; 
    echo "<td>{$row['name']}</td>"; 

}
