类 mysqli_result 的对象无法转换为字符串
我收到错误:
mysqli_result 类的对象无法转换为字符串
Object of class mysqli_result could not be converted to string
这是我的代码:
$result = mysqli_query($con, "SELECT classtype FROM learn_users WHERE username='abcde'");
echo "my result <a href='data/$result.php'>My account</a>";
推荐答案
mysqli_query() 方法返回一个对象资源给你的 $result 变量，而不是一个字符串.
The mysqli_query() method returns an object resource to your $result variable, not a string.
您需要循环它然后访问记录.您只是不能直接将它用作您的 $result 变量.
You need to loop it up and then access the records. You just can't directly use it as your $result variable.
while ($row = $result->fetch_assoc()) {
echo $row['classtype']."<br>";
}
