從MYSQLi准備好的語句中獲取查詢

Question

我准備的語句如下所示：

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
} 
echo "Connected successfully";

// prepare and bind
$stmt = $conn->prepare("INSERT INTO `devices` (`deviceName`, `type`, `deviceToken`) VALUES (?, ?, ?)");
$stmt->bind_param("sss", $deviceName, $deviceToken, $type);
$stmt->execute();
echo "executed";
$result = $stmt->get_result();
$conn->close();

我想回顯查詢。 我知道PDO方法：

$binded_query = $stmt->queryString

但是我需要使用MYSQLi。
那我該怎么辦呢？

Answer 1

$sql = "INSERT INTO `devices` (`deviceName`, `type`, `deviceToken`) VALUES (?, ?, ?)"
$stmt = $conn->prepare($sql);
echo $sql; // here you go
