PHP如何从多级数组中获取数据

Question

I have this array from JSON file and I want to get data from [url] . Array is saved as variable $data .

stdClass Object
(
    [images] => Array
    (
            [0] => stdClass Object
            (
                    [startdate] => 20190625
                    [fullstartdate] => 201906250700
                    [enddate] => 20190626
                    [url] => /th?id=OHR.SutherlandFalls_ROW5711472757_1920x1080.jpg&rf=LaDigue_1920x1080.jpg&pid=hp
            )
    )
)

Result should be like:

echo $data[0]->url; will show the link/value /th?id=...

Answer 1

Your $data variable is not an array, it's an instance of stdClass . Therefore, you can retrieve it like this:

$data->images[0]->url;
