我花了几个小时在这上面，并且在 stackoverflow 上阅读了很多答案，但没有一个有帮助。
到目前为止我所能做的就是打印集市广场 - 克利夫登对于这个例子。
$obj = json_decode($data);
$obj = $obj[0];
print $obj->{'title'};
我不知道如何访问嵌套在“图像”中的“名称”，这样我就可以得到market_square_clifden.jpg.
我将不胜感激一些指点。

正如评论者提到的，请修复您的变量格式 - 它有助于更快地获得答案。
假设您使用默认值json_decode设置后，每个 JSON 对象都会成为一个 PHP 对象。 （看json_decode 文档 https://www.php.net/json_decode%20the%20PHP%20documentation.在 php.net。）
$obj = json_decode($data);
$obj = $obj[0];
// title attribute
$obj->title
// image object
$obj->image
// image name
$obj->image->name
如果强制所有内容都是关联数组：
$obj = json_decode($data,true);
$obj = $obj[0];
// title attribute
$obj['title']
// image object
$obj['image']
// image name
$obj['image']['name']
