我想获得标题键结果。这是我的疑问：
$data = $someArray["data"];
foreach ($data as $result) {
foreach ($result as $finalres) {
echo $finalres["title"]."<br/>";
}
}
}
这是我得到的结果。该列表是diaplaying，但上面和下面显示了PHP错误。

即使结果显示，我也不知道为什么警告会一直显示？ 如何在没有PHP错误的情况下正确显示列表？
答案 0 :(得分：0)
尝试使用foreach中的键，如
foreach ($data as $key => $result) {}
答案 1 :(得分：0)
要输出结果，您只需要选择'网络'元素......
foreach ($data['webs'] as $result) {
你得到的错误是它第一次试图使用......
[query] => Plagiarism is the "wrongful appropriation" and "stealing and publication"
并迭代这个。
答案 2 :(得分：0)
尝试使用此代码：
$data = $someArray["data"]['webs'];
foreach ($data as $finalres)
{
echo $finalres["title"].PHP_EOL;
}
