當我嘗試輸入較長的文本時出現奇怪的錯誤，但它適用于一個簡單的句子，下面是我的代碼：function insert($project){    if (!empty($project->get_title()) && !empty($project->get_description()) && !empty($project->get_imgPath())) {        include 'openConnection.php';        // prepare and bind        $stmt = $dbLink->prepare("INSERT INTO projects (title, description, imgPath) VALUES (?,?,?)");        $stmt->bind_param("sss", $project->get_title(), $project->get_description(), $project->get_imgPath());        // execute        if ($stmt->execute()) {            return $stmt->insert_id;        } else {            $this->addError("Insert failed");            return false;        }    } else {        $this->addError("All fields must be provided");    }}下面這個調用上面傳遞項目的insert方法：$project = new Project();        $project->set_title($_POST['title']);        $project->set_description($_POST['description']);        $project->set_imgPath($uploadfile);        $project->insert($project);
