我的阵列有点问题,希望有人可以帮助我:
Array (
[0] => Pagekit\Blog\Model\Post Object (
[id] => x
[title] => x
[slug] => x
[user_id] => x
[date] => DateTime Object (
[date] => 2016-12-28 07:51:02.000000
[timezone_type] => 3
[timezone] => UTC
)
[content] => xxxxxxxxxxxx
[excerpt] => xxxxxxxxxxxx
[status] => xxxxxxxxxxxx
[modified] => DateTime Object (
[date] => 2016-12-28 09:17:48.000000
[timezone_type] => 3
[timezone] => UTC
)
[comment_status] => 1
[comment_count] => 0
[user] => Pagekit\User\Model\User Object (
[id] => 1
[username] => xxxxxxxxxxxx
[password] => xxxxxxxxxxxx
[email] => xxxxxxxxxxxx
[url] => xxxxxxxxxxxx
[registered] => DateTime Object (
[date] => 2016-12-15 15:33:36.000000
[timezone_type] => 3
[timezone] => UTC
)
[status] => 1
[name] => xxxxxxxxxxxx
[login] => DateTime Object (
[date] => 2016-12-27 13:55:45.000000
[timezone_type] => 3
[timezone] => UTC
)
[activation] => [permissions:protected] => [roles] => Array (
[0] => x
[1] => x
)
[data] => Array (
[admin] => Array (
[menu] => Array (
[dashboard] => x
[user] => x
[system: system] => x
[blog] => x
[system: marketplace] => x
[portfolio] => x
[site] => x
)
)
)
)
[comments] => [roles] => Array ( )
[data] => Array (
[title] => [markdown] => 1 [image] => Array (
[src] => storage/bilderbuch/bild.jpg
[alt] => bild
)
[meta] => Array (
[og:description] => Hello World!
)
)
)
)
有人可以解释一下我如何从这里得到Hello World!
或其他所有内容:(这个大数组中的最后一行)
[meta] => Array (
[og:description] => Hello World!
在$Variable
?我知道这可能是一个愚蠢的问题,但我只使用PHP一周或其他东西。
答案 0 :(得分:2)
您的$variable
是一个包含1个项目的数组
此项目是Pagekit\Blog\Model\Post
对象,因此首先您需要$variable[0]
才能到达目的地。
注意 - 此对象有多个属性,您正在寻找data
属性:$variable[0]->data
。
此属性本身是array
,其中meta
是其中一个键$variable[0]->data['meta']
,这是另一个带有og:description
键的数组。
所以你需要的最终变量实际上是
$variable[0]->data['meta']['og:description']
答案 1 :(得分:1)
我相信你已经使用过https://pagekit.com/docs/developer/orm
了在您的情况下,您可以遍历结果并返回元数据:
$meta = [];
foreach ($array as $post)
{
$meta[] = $post->data['meta'];
}
var_dump($meta);
答案 2 :(得分:0)
所以解决方案是:
$test = spliting($posts, 3);
$var1 = $test[0]->data['meta']['og:description'];
这里的分割功能只将整个数组分成3个部分。
