數組的提取元素

Question

我有一個數組，我通過json_decode返回，並且只想提取下面的image_url。我會從中運行哪些php命令，以獲取下面的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] => 
     [width] => 275 
     [height] => 183 
     [votes_count] => 0 
     [favorites_count] => 0 
     [comments_count] => 0 
     [nsfw] => 
     [license_type] => 0 
     [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 ( 
      [id] => 3677956 
      [username] => jsniff12 
      [firstname] => Jacob 
      [lastname] => Sniff 
      [city] => 
      [country] => 
      [fullname] => Jacob Sniff 
      [userpic_url] => /graphics/userpic.png 
      [upgrade_status] => 0 
      [followers_count] => 0 
      [affection] => 0 
     ) 
    ) 
)

請在此處發帖之前嘗試做點努力。你可以閱讀關於php arrays和objects。

您將能夠得到image_url方式如下：

echo $array[0]->image_url; 

注：這種問題很可能被關閉，因爲它太具體，太簡單了。
