相同連接中的連續查詢不起作用

Question

以下代碼正常工作，但行$connection->query('call user_create(145552, \'a@a.com\');');未在數據庫中創建用戶。

function updateFacebook($id) { 

    $connection = mysqli_connect('localhost', 'root', '', 'databasename'); 
    $count = $connection->query('call user_by_facebook_read(' . $id . ');')->num_rows; 

    if ($count == 0) { 

     $request = \Slim\Slim::getInstance()->request(); 
     $body = $request->getBody(); 
     $json = json_decode($body); 
     $token = $json->token; 

     $facebook = new Facebook(array(
      'appId' => 'value', 
      'secret' => 'value', 
      'cookie' => true 
     )); 

     $facebook->setAccessToken($token); 

     $facebook->api('/me/feed', 'post', array(
      'message' => 'message', 
      'picture' => 'https://www.google.com.br/images/srpr/logo4w.png', 
      'link' => 'https://www.google.com.br', 
      'description' => 'description', 
      'name' => 'name', 
      'caption'=> 'caption' 
     )); 

     $connection->query('call user_create(145552, \'a@a.com\');'); 

    } 

    $connection->close; 

    $json = json_encode(array(
     'r' => true 
    )); 

    echo $json;  

} 

如果我運行下面的代碼也工作得很好：

$connection = mysqli_connect('localhost', 'root', '', 'databasename'); 
$connection->query('call user_create(145552, \'a@a.com\');'); 
$connection->close; 

如果我關閉$count後的連接和前再次打開它user_create調用它也適用。

發生了什麼事？

您需要對結果運行->close()，但是您放棄了該結果。所以：

$result = $connection->query(..); 
$count = $result->num_rows; 
$result->close(); 

and after CALL()s in MySQLi it seems to need this:

$connection->next_result();
