如何从阵列中获取内容？

Question

I have converted a GraphObject into an array.

How do I get just the names instead of the whole array? Like: You are friend with..

Bruce Willis
John Travolta

How my code looks like:

$friends = (new FacebookRequest( $session, 'GET', '/me/friends' ))
    ->execute()
    ->getGraphObject()
    ->asArray();
echo '<pre>' . print_r( $friends,1 ) . '</pre>';

And the results looks like this for the moment:

Answer 1

foreach ($friends['data'] as $friend) {
    echo $friend->name . "<br />";
}

You want to loop through the data array, and store them all in the variable $friend, $friend is an object with id and name attribute, so you can call them like this: $friend->name and $friend->id
