从数组中获取数据时出现问题

Question

我有一个如下数组:

Array (
    [feed] => Array (
        [0] => Array (
            [title] => Stackoverflow
            [permalink] => http://www.stackoverflow.com
        )
        [1] => Array (
            [title] => Yahoo
            [permalink] => http://www.yahoo.com
        )
    )
)

我怎样才能获得头衔？我试过这个:

$data['feed']['title']

Answer 1

不应该是这样的:

$data['feed'][0]['title']
