从空值创建默认对象（ stdClass? ）

Question

脚本运行良好，但只有当我提取用户组时，它才会说：

SteamUser.php (132): 从空值创建默认对象

    function getProfileData() {

    //Set Base URL for the query:
    if(empty($this->vanityURL)) {
        $base = "http://steamcommunity.com/profiles/{$this->userID}/?xml=1";
    } else {
        $base = "http://steamcommunity.com/id/{$this->vanityURL}/?xml=1";
    }

    try {
        $content = SteamUtility::fetchURL($base);
        if ($content) {
            $parsedData = new SimpleXMLElement($content);
        } else {
            return null;
        }
    } catch (Exception $e) {
        //echo "Whoops! Something went wrong!\n\nException Info:\n" . $e . "\n\n";
        return null;
    }

    if(!empty($parsedData)) {

            }

        }                    

    }
}
  .

。 . 我已经尝试过使用关联数组，但是没有用；也许做这一切都是新的。 -_-

所以，我根本无法设置 error_reporting(0) 或 ini_set。

我也尝试使用 new stdClass()。但我也没有让它运行。

你创建一个数组。

$this->groups = array();

但是在这个数组中你没有创建任何对象。您只需将此数组的元素（未初始化）用作对象。您应该在 132. 行之前添加此行。

$this->groups[$i] = new Group();

或类似的东西。 如果您没有 Group 课程，您应该尝试

$this->groups[$i] = new stdClass();
