PHP从facebook var中回显出多维数组

Question

我有一个 facebook 数组，我正在尝试呼出名称和 ID。

我只有这个数组：$friends_list。

当我使用这段代码时：

print_r($friends_list);

然后下面会出现以下内容：但是我如何循环遍历这些内容？或者如果我只是想知道有多少个名字或者只是通过 id 调用一个 var。简而言之，我如何回显 $friends_list 这是一个多维数组？

Array ( [data] => Array ( [0] => Array ( [name] => Wendy Cukierski [id] => 524320383 ) [1] => Array ( [name] => Leticia Mercado Correa [id] => 537763225 ) [2] => Array ( [name] => Olivia Urbina [id] => 538711855 ) [3] => Array ( [name] => Ruth Albrecht [id] => 541610111 ) [4] => Array ( [name] => Josh Brahm [id] => 577546485 ) [5] => Array ( [name] => Kim Yu [id] => 583515871 ) [6] => Array ( [name] => SisterTracey Dugas [id] => 643567171 ) [97] => Array ( [name] => Mary Martinez [id] => 100004696266210 ) ) [paging] => Array ( [next] => https://graph.facebook.com/1566027944/friends?limit=5000&offset=5000&__after_id=100004696266210 ) )
