數組中的Facebook數據的foreach循環

我正在製作Facebook圖形API調用並獲取數據。但由於某種原因無法循環。是因爲它受到保護嗎？或者我的foreach循環是錯誤的。數組中的Facebook數據的foreach循環

這是該數據時，我在我看來var_export（$ user_pages）

array (size=2) 
    'data' => 
    array (size=2) 
     0 => 
     object(stdClass)[92]

      public 'category' => string 'Book Store' (length=10) 
      public 'category_list' => 
      array (size=1) 
       0 =>

      public 'after' => string 'NDk1ODY4MjcwNjE4MDAw' (length=20

var_export（$ user_pages）

array ('data' => array (0 => stdClass::__set_state(array('access_token' => 'EAAZAbF70RRXMBAAesxifymoAnCRnrbp7n8t8sUG3gYkImVVZA1CxkUAmqZBA1SUdh7HZCg3EBHrpAcWiIHb2A5Secyhnx70qGW7hyTStE5KX842ZB5mlzO1RZAjkIsaWzN7e5uZCHZAfbQXLQo7We54ZACDjkbQ4TLIwZD', 'category' => 'Book Store', 'category_list' => array (0 => stdClass::__set_state(array('id' => '197048876974331', 'name' => 'Book Store',)),), 'name' => 'Unofficial Dev777', 'id' => '1791907811022418', 'perms' => array (0 => 'ADMINISTER', 1 => 'EDIT_PROFILE', 2 => 'CREATE_CONTENT', 3 => 'MODERATE_CONTENT', 4 => 'CREATE_ADS', 5 => 'BASIC_ADMIN',),)), 1 => stdClass::__set_state(array('access_token' => 'EAAZAbF70RRXMBACzv5AV8MGVBTh1U4XgCXh7a9gs9R5JAQZBKf7gsdOhe6DKxk1Sy0cD2QtaDoHZBs6O13hWoL3W39M0WgNtpUssWam2PMskfEF6zZBypmLIiyQlj2ZC2Dq5tqTjH2WohusLdwyrODi4d9kzgBH4ZD', 'category' => 'Business Services', 'category_list' => array (0 => stdClass::__set_state(array('id' => '187133811318958', 'name' => 'Business Services',)),), 'name' => 'Self', 'id' => '495868270618000', 'perms' => array (0 => 'ADMINISTER', 1 => 'EDIT_PROFILE', 2 => 'CREATE_CONTENT', 3 => 'MODERATE_CONTENT', 4 => 'CREATE_ADS', 5 => 'BASIC_ADMIN',),)),), 'paging' => stdClass::__set_state(array('cursors' => stdClass::__set_state(array('before' => 'MTc5MTkwNzgxMTAyMjQxOAZDZD', 'after' => 'NDk1ODY4MjcwNjE4MDAw',)),)),)

這是我的循環會拋出一個錯誤說「無效參數提供的foreach（）（查看：/Library/WebServer/Documents/fbLogin/app/views/hello.blade.php）「

@foreach($user_pages as $pages) 
       {{ $pages->name }} 
       {{ $pages->category }} 
@endforeach

我也試過var_dump（$ user_pages-> backingData）它顯示錯誤說「無法訪問受保護的財產Facebook \ GraphObject :: $ backingData」

是數據無法訪問？

已發佈結果var_export **好我在調用圖形api時使用了facebook asArray（）方法，現在數據更具可讀性。只需要循環它。 *的asArray（）後已經更新後新的var_dump

嘗試使'var_export（）'嘗試響應 –

這將如何幫助？ – simba777

我的意思是你要發佈[var_export（）]（http://php.net/manual/en/function.var-export.php）而不是var_dump，因爲我試圖迭代你的數組 –

改變了我的API請求到

return $response->getGraphObject()->getProperty('data')->asArray();

從

return $response->getGraphObject();

得到一個簡單的數組數據現在通過它，我很容易使用foreach循環使用

@foreach($user_pages as $user_pages) 
       {{ $user_pages->name }} 
       {{ $user_pages->category }} 
@endforeach
