Question

我想使用invitable_friends循环

从Facebook foreach API循环图像

$beranda = json_decode(get_html("https://graph.facebook.com/$user->id/invitable_friends?fields=id,picture,name&limit=7&access_token=$accessToken"))->data;

foreach($beranda as $friendsid){


echo  '<img src="'.$friendsid->picture.'">';
 }

面临此错误

Catchable fatal error: Object of class stdClass could not be converted to string in

Thia是$beranda

的结构

Array
  (
  [0] => stdClass Object
    (
        [id] => AVkUphJYSPksSJ47kLM8PGm8cOAjlNLG5NWUMp5IhdSCWkziShWsSVkRdVx1Z73jeu7B73bRzYnecUqD27V3xO36Uh27LD16mVZlRKGKgDLZIQ
        [picture] => stdClass Object
            (
                [data] => stdClass Object
                    (
                        [is_silhouette] => 
                        [url] => https://scontent.xx.fbcdn.net/v/t1.0-1/p50x50/13731636_1671465926510554_2031112688215377192_n.jpg?oh=5a85a07de9ab4011e17378a38bac941c&oe=5831B7E6
                    )

            )

        [name] => Sam Saifi
    )

$friendsid->picture

的var转储

       object(stdClass)#38 (1) {
           ["data"]=>
             object(stdClass)#39 (2) {
              ["is_silhouette"]=>
                 bool(false)
                    ["url"]=>
              string(145) "https://scontent.xx.fbcdn.net/v/t1.0-1/p50x50/10155363_1386729058279575_5046516924942639505_n.jpg?oh=f55ea91f39815a7fb9661e65899d0a02&oe=581B8AE2"

} }

Answer 1

根据您的print_r结果，您需要更改行...

echo  '<img src="'.$friendsid->picture.'">';

到

echo '<img src="' . $friendsid->picture->data->url . '">';

因为你在另一个父对象中的另一个对象[picture]中的对象[data]中调用参数[url]。我会推荐一个关于面向对象的php的训练营课程，无论如何很高兴它有效！
