准备好mysqli语句 - 对于num_rows总是返回0

Question

我在这一份准备好的声明中过去一小时都在工作。

每次都会num_rows返回$user_id。

我已经在phpmyadmin中手动运行我的数据库查询，并且没有任何问题。 if ($statement = $mysqli->prepare("SELECT google_id FROM google_users WHERE google_id = ? LIMIT 1")) { $statement->bind_param("i", $user_id); $statement->execute(); $statement->store_result(); if ($statement->num_rows < 1) { $alerts .= '<div class="alert alert-danger" role="alert">Your login session was not valid. Please log in again.</div>'; } $statement->free_result(); $statement->close(); } 也设置得很好。

public function initSession()
{
    $sessionConfig = new SessionConfig();
    $sessionConfig->setOptions([
        'cookie_lifetime'     => 7200, //2hrs
        'remember_me_seconds' => 7200, //2hrs This is also set in the login controller
        'use_cookies'         => true,
        'cache_expire'        => 180,  //3hrs
        'cookie_path'         => "/",
        'cookie_secure'       => Functions::isSSL(),
        'cookie_httponly'     => true,
        'name'                => 'cookie name',
    ]);
    $sessionManager = new SessionManager($sessionConfig);
    // $memCached = new StorageFactory::factory(array(
    //     'adapter' => array(
    //        'name'     =>'memcached',
    //         'lifetime' => 7200,
    //         'options'  => array(
    //             'servers'   => array(
    //                 array(
    //                     '127.0.0.1',11211
    //                 ),
    //             ),
    //             'namespace'  => 'MYMEMCACHEDNAMESPACE',
    //             'liboptions' => array(
    //                 'COMPRESSION' => true,
    //                 'binary_protocol' => true,
    //                 'no_block' => true,
    //                 'connect_timeout' => 100
    //             )
    //         ),
    //     ),
    // ));

    // $saveHandler = new Cache($memCached);
    // $sessionManager->setSaveHandler($saveHandler);
    $sessionManager->start();
    return Container::setDefaultManager($sessionManager);
