I\'m working on a project for uni and have been using the following code on a testing server to get all devices from a table based on a user_

Assuming you can't use get_result() and you want an array of devices, you could do:

public function getAllDevices($user_id) {
    $stmt = $this->conn->prepare("SELECT device_id, device_name, device_info FROM devices WHERE  primary_owner_id = ?");
    $stmt->bind_param("i", $user_id);
    $stmt->execute();
    $stmt->bind_result($id, $name, $info);
    $devices = array();

    while($stmt->fetch()) {
        $tmp = array();
        $tmp["id"] = $id;
        $tmp["name"] = $name;
        $tmp["info"] = $info;
        array_push($devices, $tmp);
    }
    $stmt->close();
    return $devices;
}

This creates a temporary array and stores the data from each row in it, and then pushes it to the main array. As far as I'm aware, you can't use SELECT * in bind_result(). Instead, you will annoyingly have to type out all the fields you want after SELECT
