php - 提取数组元素

Question

我有一个通过 json_decode 返回的数组，并且只想提取下面的 image_url。我会从中运行什么 php 命令来获取下面的 image_url？

[0] => 
    stdClass Object ( 
        [id] => 36210508 
        [name] => Untitled 
        [description] => 
        [times_viewed] => 2 
        [rating] => 0 
        [created_at] => 2013-05-31T15:08:36-04:00 
        [category] => 0 
        [privacy] =>

        [height] => 183 
        [votes_count] => 0 
        [favorites_count] => 0 
        [comments_count] => 0 
        [nsfw] =>

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

            [userpic_url] => /graphics/userpic.png 
            [upgrade_status] => 0 
            [followers_count] => 0 
            [affection] => 0 
        )
    )

请尝试在此处发布问题之前做出一些努力。您可以阅读有关 php数组和对象的信息。

您将能够通过image_url以下方式获得：

echo $array[0]->image_url;

注意：这种问题很可能会被关闭，因为它太具体太基础了。
