从数组中获取特定键

Question

我有这个数组：

$client = new OAuth2\Client($client_id, $client_secret, $region, $locale, $redirect_uri);

$array = array('id'=>'13146');
$type = 'quest';
$r = $client->fetch($type,$array);
echo '<pre>';
print_r ($r);
echo '</pre>';

?>

输出：

[result] => Array
    (
        [id] => 13146
        [title] => Generosity Abounds
        [reqLevel] => 77
        [suggestedPartyMembers] => 0
        [category] => Icecrown
        [level] => 80
    )

我只想读出[标题]和[类别]。我尝试了几种解决方案，但对我没有任何用处。谢谢

Answer 1

要访问 title 和 category，您需要执行以下操作：

echo $r['result']['title'];    // Generosity Abounds
echo $r['result']['category']; // Icecrown
