PHP类今天完全忘记了一些事情-对不起

Question

真的很抱歉，我今天太胖了，但是我忘记了怎么做一些简单的事情--最近太多时间不在php里了。

想要使用操作系统phpapi如何打印出单独的行-请看，我告诉过你我今天很胖

 // The fields we will be fetching.


 if (isset($_GET['test']) && $_GET['test'] == 'plaxo') {
    // plaxo is a PortableContacts end-point so doesn't know about the OpenSocial specific fields
    $profile_fields = array();
  } else {
    $profile_fields = array(
        'aboutMe',
        'displayName',
        'bodyType',
        'currentLocation',
        'drinker',
        'happiestWhen',
        'lookingFor'
    );
  }

//拉取的好友数量

  $friend_count = 2;

$batch = $osapi->newBatch();
    // Fetch the current user.
      $self_request_params = array(
          'userId' => $userId,              // Person we are fetching.
          'groupId' => '@self',             // @self for one person.
          'fields' => $profile_fields       // Which profile fields to request.
      );
  $batch->add($osapi->people->get($self_request_params), 'self');

  // Fetch the friends of the user
  $friends_request_params = array(
      'userId' => $userId,              // Person whose friends we are fetching.
      'groupId' => '@friends',          // @friends for the Friends group.
      'fields' => $profile_fields,      // Which profile fields to request.
      'count' => $friend_count          // Max friends to fetch.
  );
  $batch->add($osapi->people->get($friends_request_params), 'friends');

  // Get supportedFields Request
  $batch->add($osapi->people->getSupportedFields(), 'supportedFields');

  // Send the batch request.
  $result = $batch->execute();

假设我想打印出"aboutMe"，得到的回声是什么？因为回显$result‘’aboutMe‘不起作用。

虽然我不是php专家，而且我对你使用的具体产品一无所知，但我发现使用var_dump($result)对调试有很大的帮助。
