php - 错误：注意：试图获取非对象的属性

Question

我有以下获取数据列表的代码，我正在尝试按“名称”过滤此数据，但出现此错误：

错误：注意：试图获取非对象的属性

代码

 $bpl = 31;

$marketFilter = MarketFilter::create()
    ->setCompetitionIds(array($bpl));

$eventBetfair->withMarketFilter($marketFilter);

$bplevents = $eventBetfair->getResults();

print_r($bplevents->name);

数据/结果

以下结果是我打印 '$bpevents' 时的结果，如下所示：

print_r($bplevents);

输出：

Answer 1

输出是一个数组，不是一个对象。使用 $bpevents->name 您正在调用一个对象。我会做 $bpevents['name']，这是调用数组的正确方法。

编辑：请检查您的输出。您的输出告诉您出了什么问题。你有一个多维数组。也许，在美化你的输出之后，我意识到你应该访问这个： $bplevents[0]['event']['name']..你也可以

foreach($bplevents as $amount => $array){
     print_r($array['event']['name']);
}

Answer 2

$bpevents 传递的是数组而不是对象。正确的称呼方式如下。

print_r($bplevents[0]['element']['namne']);
