Question

我在日志中不断收到此错误，似乎没有做任何事情/停止工作，但我想知道它是什么。

任何人都可以告诉我我的bind_param声明在哪里出错吗？我尝试添加s（删除s）删除变量，它只是不断弹出。

这是它引用的代码 -

第79行 -

function searchData()
{
  $servername = $this->servername;
  $username = $this->username;
  $password = $this->password;
  $dbname = $this->dbname;
  #Opens the MYSQL Connection
  $conn = mysqli_connect($servername, $username, $password, $dbname);
    if (!$conn)
    {
      die("Connection failed: " . mysqli_connect_error());
    }
    ##Prepares the statement
    $stmt = $conn->prepare("SELECT * FROM dns WHERE domain LIKE '$this->domainname' ");
    $stmt->bind_param('s',$this->domainname);
    $stmt->execute();
    $result = $stmt->get_result();

Answer 1

$stmt = $conn->prepare("SELECT * FROM dns WHERE domain LIKE ? ");
$stmt->bind_param('s',$this->domainname);

您在字符串中输入问号并将其插入。这就是它的工作原理。尝试在第79行而不是你所放的
