我正在尝试从JSON数组中获取数据-该数组的结构非常复杂。

我正在尝试获取标题密钥结果。下面是我的问题：
$data = $someArray["data"];
foreach ($data as $result) {
foreach ($result as $finalres) {
echo $finalres["title"]."<br/>";
}
}
}这是我得到的结果。该列表正在显示，但上面和下面都显示了PHP错误。

尝试在foreach中使用键，如
foreach ($data as $key => $result) {}

要只输出结果，你只需要选择“webs”元素...
foreach ($data['webs'] as $result) {你得到的错误是它第一次尝试使用...
[query] => Plagiarism is the "wrongful appropriation" and "stealing and publication"然后迭代这段代码。
