php-Facebook SDK(5.0)-图形API请求-分页(如何获取所有结果)

我正在开发一个简单的Facebook应用程序,该应用程序需要获取用户所有的“页面喜欢”,以便将它们与作为匹配标识符的“页面ID”的预构建列表进行比较.

我可以得到一个喜欢的清单.但是,我只能在响应中获得“每页”赞100个.其中一些人有数千个赞,因此我需要确保可以从所有页面中收集所有数据.

一个简单的$fb-> next($response);会得到我的下一页(所以,而不是100个喜欢,我可以得到200个)..但是,当我将其放入循环中时,我的脚本陷入了无限循环,因为即使总有一个“下一页”,即使没有结果.

是否有任何内置方法可以轻松遍历这些结果,还是我必须在每次迭代中检查请求级别的数据结构,以了解这些项目是否已返回数据？

//this results in an infinite loop

$request = $fb->request('GET', '/'.$fid['id'].'/likes?limit=9999');

do {
    $graphNode = $fb->getClient()->sendRequest($request);
    $paging = $graphNode->getGraphEdge();
    $graphEdge = $graphNode->getGraphEdge()->asArray();     
    $likes = array_merge($likes, $graphEdge);
} while ($fb->next($paging)); // ERROR IS HERE!!  SET while($paging = $fb->next($paging)); INSTEAD

通过响应评论更新如下：

        $request = $fb->request('GET', '/'.$fid['id'].'/likes?limit=9999');
    $graphNode = $fb->getClient()->sendRequest($request);
    $graphEdge = $graphNode->getGraphEdge();

    if ($fb->next($graphEdge)) {  

        $likesArray = $graphEdge->asArray();
        $lc = count($likesArray);
        $totalLikes = array_merge($totalLikes, $likesArray); 

        while ($graphEdge = $fb->next($graphEdge)) { 

            $likesArray = $graphEdge->asArray();
            $lic = count($likesArray);
            $totalLikes = array_merge($totalLikes, $likesArray);

        }

    } else {

        $likesArray = $graphEdge->asArray();
        $totalLikes = array_merge($totalLikes, $likesArray);

    }

解决方法:

这就是我一直使用的.通过将$likes变量更改为$data参数并通过该函数传递其他GraphEdge调用,您始终可以使用循环是一个函数.

$getPages = $this->fb->get('/me/likes?limit=100');
$likes = $getPages->getGraphEdge();

$totalLikes = array();

        if ($this->fb->next($likes)) {  
            $likesArray = $likes->asArray();
            $totalLikes = array_merge($totalLikes, $likesArray); 
            while ($likes = $this->fb->next($likes)) { 
                $likesArray = $likes->asArray();
                $totalLikes = array_merge($totalLikes, $likesArray);
            }
        } else {
            $likesArray = $likes->asArray();
            $totalLikes = array_merge($totalLikes, $likesArray);
        }

        return $totalLikes;
