通過Facebook api「喜歡」循環播放

Question

嘿，我試圖讓所有喜歡的壁帖在PHP中。陣列框架是這樣的：

Array ( 
[data] => Array ( 
    [0] => Array ( 
     [id] => XXXXXXXX_XXXXXXXXXXX 
     [from] => Array ( 
      [name] => Bob Barker 
      [id] => XXXXXXXXXXX 
     ) 
     [message] => This is a message here!!! 
     [story] => We shared a message with others 
     [story_tags] => Array ( 
      [0] => Array ( 
       [0] => Array ( 
        [id] => XXXXXXXXXX 
        [name] => Bob Barker 
        [offset] => 0 
        [length] => 11 
        [type] => user 
       ) 
      ) 
      [19] => Array ( 
       [0] => Array ( 
        [id] => XXXXXXXXXXXXXXXXXXXXXXX 
        [name] => NAME 
        [offset] => 19 
        [length] => 5 
        [type] => page 
       ) 
      ) 
     ) 
     [picture] => [removed] 
     [link] => [removed] 
     [name] => Timeline Photos 
     [caption] => This is just a caption for the post here 
     [properties] => Array ( 
      [0] => Array ( 
       [name] => By 
       [text] => NAME 
       [href] => [removed] 
      ) 
     ) 
     [icon] => https://fbstatic-a.akamaihd.net/rsrc.php/v2/yD/r/aS8ecmYRys0.gif 
     [actions] => Array ( 
      [0] => Array ( 
       [name] => Like 
       [link] => [removed] 
      ) 
     ) 
     [privacy] => Array ( 
      [value] => 
     ) 
     [type] => photo 
     [status_type] => shared_story 
     [object_id] => XXXXXXXXXXXXXXXX 
     [application] => Array ( 
      [name] => Photos 
      [id] => XXXXXXXXXX 
     ) 
     [created_time] => 2014-02-12T21:33:17+0000 
     [updated_time] => 2014-02-12T21:33:17+0000 
     [likes] => Array ( 
      [data] => Array ( 
       [0] => Array ( 
        [id] => XXXXXXXXXXXX 
        [name] => John Doe 
       ) 
       [1] => Array ( 
        [id] => XXXXXXXXXXXX 
        [name] => Steve Doe 
       ) 
      ) 
      [paging] => Array ( 
       [cursors] => Array ( 
        [after] => XXXXXXXXXXXXXXXX 
        [before] => XXXXXXXXXXXX== 
       ) 
      ) 
     ) 
    ) 

我當前的PHP代碼：

$feed = $facebook->api('/me/home'); //This is the array above 

foreach($feed['data'] as $post) { 
    $story = (isset($post['story']) ? $post['story'] : null); 
    $id = (isset($post['id']) ? $post['id'] : null); 
    $name = (isset($post['name']) ? $post['name'] : null); 
    $message = (isset($post['message']) ? $post['message'] : null); 
    $post_link = (isset($post['actions'][0]['link']) ? $post['actions'][0]['link'] : null); 
    $picture = (isset($post['picture']) ? $post['picture'] : null); 

    foreach($post['likes'] as $liked) { 
     echo $post['id']; 
    } 

    echo $name . ' ' . $story . ' it was: ' . $message . ' and ' . $post_link . ' and <img src="' . $picture . '" /><br />'; 
    echo '======================================================================================================='; 
} 

的

foreach($post['likes'] as $liked) { 
     echo $post['id']; 
} 

似乎並不奏效原樣。我爲了讓它遍歷數組中所有「喜歡」的帖子而丟失了什麼？

Answer 1

是

foreach($post['likes'] as $liked) { 
     echo $post['id']; 
} 

將無法​​工作，因爲

$post['likes']元素又是一個嵌套的數組作爲

likes => array => data => array=> .. 

所以你需要做環路

if(array_key_exists('data',$post['likes'])){ 
     foreach($post['likes']['data'] as $liked=>$val) { 
      echo '<br />Like ID: ' .$val["id"].'<br />' ; 
     } 
    } 

它始終是更好，如果陣列關鍵在做循環之前存在，因此，如果返回的數據不包含關鍵你沒有得到不確定的指數錯誤做了檢查。

Answer 2

嘗試

foreach($post['likes']->data as $like) { 
    echo $like->id; 
}
