提取数组的元素

Question

我有一个通过json_decode返回的数组，想要只提取下面的image_url。我将从中运行什么php命令，以获取下面的image_url？

[0] => 
    stdClass Object ( 
        [id] => 36210508 
        [name] => Untitled 
        [description] => 
        [times_viewed] => 2 
        [rating] => 0

        [images] => 
            Array ( 
                [0] => 
                stdClass Object ( 
                    [size] => 4 
                    [url] => http://pcdn.500px.net/36210508/5de3b4bb9cdee9f429e2a329a1d0619dd5b28ce1/4.jpg 
                )
            )
        [store_download] => 
        [store_print] => 
        [user] =>

请在此处发布问题之前尝试做一些努力。您可以阅读有关php arrays和objects的信息。

您可以通过以下方式获取image_url：

echo $array[0]->image_url;
