从 MySQLi 和 PHP 中的准备好的语句中获取数据

Question

您好，我正在尝试从我在 PHP 类中编写的准备好的语句中获取数据，并且我已经尝试了很多，请帮助这里是类成员中的 PHP 函数

public function Check() {
    $email = $this->getEmail();
    $user = $this->getUsername();
    $check = "SELECT firstName,lastName FROM members WHERE Email = ? AND Username = ? AND isActive = '1' ";
    $stmt = $this->conn->prepare($check);
    $stmt->bind_param("ss", $email, $user);
    $stmt->execute();
    return $stmt->fetch();
}

我想通过包含类并创建它的对象来获取另一个页面中的数据。这是我的尝试

<?php
                    $member = new Members();
                    $email = $member->setEmail(strip_tags(htmlspecialchars(trim($_GET['e']))));
                    $user = $member->setUsername(strip_tags(htmlspecialchars(trim($_GET['u']))));
                    if ($member->Check()) { echo $firstname." ".$lastname; } ?>

请帮助.. 谢谢

您需要bind the result variables:

$stmt->execute();
$stmt->bind_result($firstname, $lastname);
$stmt->fetch();
return array('firstname' => $firstname,'lastname' => $lastname);

$member = new Members();
$email = $member->setEmail(strip_tags(htmlspecialchars(trim($_GET['e']))));
$user = $member->setUsername(strip_tags(htmlspecialchars(trim($_GET['u']))));
$results = $member->Check();
if ($results) { echo $results['firstname']." ".$results['lastname']; } ?>
