如何访问多维关联数组?

Question

我有这个数组从数据库查询返回。我不确定如何检索[url]的值?

请建议。谢谢。

Array (
[1] => Array (
[0] => Array (
[url] => ''
[poster] => ''
[skin] => siteorigin
[ratio] => 1.777
[autoplay] => 0
[info] => Array (
[grid] => 0
[cell] => 0
[id] => 0
[class] => ''
)
)
[1] => Array (
[title] =>
[text] => ''
[filter] => 1
[info] => Array (
[grid] => 1
[cell] => 0
[id] => 1
[class] => WP_Widget_Text
)
)
)

如果您只是想合法地从特定数组中获取值，则应该可以正常工作:

$arr[1][0]['url']

多维数组只是数组中的数组，所以每个括号操作符产生一个新的数组，可以进一步解引用，直到得到你想要的值。
