所以我有一个来自JSON请求的嵌套JSON响应，我在解析嵌套的JSON数据以获取某个值时遇到了麻烦，我已对需要的数据进行了注释（“ link”：“ http：/ /i.imgur.com/DnjD527h.gif“）需要在两个位置提取数据，请参阅JSON数据以获取注释。由于我对数组没有很好的了解，因此需要一些帮助来解决问题。谢谢

目前这是我正在尝试的
$gifs=file_get_contents(__DIR__ ."/backend_web/Json/tags/test.txt");
$local=$gifs;
$decoded=json_decode($gifs,true);
//print_r($decoded);
foreach ($decoded as $y) {
foreach ($y->images as $z) {
$data = $z->link
}
}
但出现此错误。 注意：尝试在第29行的C：\ xampp \ htdocs \ test \ test.php中获取非对象的属性“链接” 任何帮助将不胜感激
答案 0 :(得分：1)
使用对象比使用数组更好：
$decoded=json_decode($gifs);
然后使用以下循环：
foreach ($decoded->data->items as $y) {
if (isset($y->images)) {
foreach ($y->images as $x) {
$data = $x->link;
}
}
}
某些对象没有“ images”属性，这就是为什么会出现错误。通过 isset 函数消除了。
