I have a PHP file in which there is a function which is used to check the user input-output but somehow that is not working and when I debug it then there is an error as 'Call to undefined method mysqli_stmt::get_result' here is function code
public function getUserByEmailAndPassword($email, $password) {
$stmt = $this->conn->prepare("SELECT * FROM users WHERE email = ?");
$stmt->bind_param("s", $email);
if ($stmt->execute()) {
$user = $stmt->get_result()->fetch_assoc();
$stmt->close();
// verifying user password
$salt = $user['salt'];
$encrypted_password = $user['encrypted_password'];
$hash = $this->checkhashSSHA($salt, $password);
// check for password equality
if ($encrypted_password == $hash) {
// user authentication details are correct
return $user;
}
} else {
return NULL;
}
}
and I don't have mysqlnd enabled on my hosting provider's server and I can't enable it right now because hosting company won't provide me SSL certificate, so there has to find some alternative way for the same and also not to change the outcome too, and I have tried this Call to undefined method mysqli_stmt::get_result answer but no luck as I am relatively new to the PHP and cannot deduce that answer to use with my condition and have tried other ansers than accepted answer but they are not working for unknown reasons, that is the reason I had to ask it here.... any help would be appreciated...thanks here is the whole code in which above function lies

the login file which uses above functions to check the conditions
<?php require_once 'include/DB_Functions.php';
$db = new DB_Functions(); $response = array("error" => FALSE);
if (isset($_POST['email']) && isset($_POST['password'])) {
$email = $_POST['email'];

$response["user"]["email"] = $user["email"];
$response["user"]["created_at"] = $user["created_at"];
$response["user"]["updated_at"] = $user["updated_at"];
echo json_encode($response);
} else {
// user is not found with the credentials
$response["error"] = TRUE;
$response["error_msg"] = "Login credentials are wrong. Please try again!";
echo json_encode($response);
}
} ?>
meanwhile i tried to work with PDO to get mysqli out of equation but that is also returning no queries is well
public function getUserByEmailAndPassword($email, $password) {
$dsn = 'mysql:host=hostname; dbname=dbname';
$user = username;
$password = password;
$db= new PDO($dsn, $user, $password);
$params = array(':email' => $email,':password'=>$password );
$stm = $db->prepare('SELECT * FROM users WHERE email= :email AND password= :password');
if($stm->execute($params)){
$user = $stm->fetch(PDO::FETCH_ASSOC);
// verifying user password
$salt = $user['salt'];
$encrypted_password = $user['encrypted_password'];
$hash = $this->checkhashSSHA($salt, $password);
// check for password equality
if ($encrypted_password == $hash) {
// user authentication details are correct
return $user;
}
} else {
return NULL;
}
}
